It not only acts as a FR but also retains the dimensional stability of the coated substrates in a fire [4]. FIGURE 5. Mixtures of APP and polyol components release water which partially hydrolyzes the APP chains leading to more acidic polyphosphate and shorter chain products with phosphoric acid terminal groups [18–20]. Furthermore, they are not compatible with the polymeric matrix, and this weakens the mechanical properties of the materials. The P atoms are not the first inter-tetrahedral neighbour of DBO because the direction of the P=O bonds tends to approach the centre of adjacent rings in P4O10 or P2O5; therefore, a defect in the glass structure will result. 23.14 (b)), particles of APP seem to be bigger and their shape is highly oriented toward injection flow. These results are already enough to show a synergistic effect of CNT when added with APP. : 65997-17-3 NAS/CWTC 036-82 Formula Weight: Unknown Chemical Formula: (MPO3)n M2O Where M = Na and/or 1/2 Zn n = 5 P2O5 = 55-61% Description: White to colorless glassy plates Use: Corrosion inhibitor.

PA 6 is a well-known char-forming polymer, and the interaction between the amide groups of PA 6 and an acid catalyst at a high temperature can form some cross-linking chemical structures, which strengthen the char layer. Some 2 mm of thickness was thin enough to highlight a difference in behaviour between the two materials. On the other hand, polymerization carried out at −50°C and catalyzed by Mg3 occurred with almost quantitative conversion and a substantially linear polymer was formed (Mn=1.6×104) [438]. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. 28, 155–157). Bacteria-responsive multifunctional nanogel for targeted antibiotic delivery. Find Similar Structures. In the next stage, DOX derivative containing an azide group was reacted with the butynyl groups in polyphosphate block, and finally dithiol bis(propanoic dihydrazide) as cross-linker was added [449]. The nanogels were also synthesized by a convenient arm-first procedure, using MPEG as the macroinitiator to initiate ROP of a bifunctional monomer 3,4-dithio-1,6-diyl bis(ethylene phosphate) (166). Chem. 23.15. These micelles were loaded with doxorubicin to evaluate their potential as drug nanocarriers [439]. Most polyphosphate fertilizers will have 40 to 60 percent of the phosphorus remaining in the orthophosphate form. HFFR polyether based TPU compound. Hu et al. The first test which was done to characterize the flame-retardant properties of these two samples was the vertical UL94 test on samples with a thickness of 3 mm. Valuable time for escape or rescue is thus gained in the event of a fire [15]. Indeed, for the same amount of APP, the addition of a very small quantity of CNTs enhances the FR properties compared to the sample with APP only. Polyphosphoric acid trimethylsilyl ester. Both materials (with and without CNTs) were classified V0. 106529 View Pricing & Availability Recommended Products. This difference in particles’ size (i.e. Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP),) is an inorganic compound with formula Na 5 P 3 O 10.

Halogen free TPE compound for industrial cable. Advance Inorganics - Offering Ammonium Polyphosphate, Chemical Formula: N(oh)2 at Rs 210/kilogram in Delhi, Delhi. Intumescent formulations consist of an acid source, such as APP; a polyhydric source of carbon to form the char, such as pentaerythrithol; a blowing agent, such as melamine or similar compounds; and resin binders, such as vinyl copolymers, epoxies, polyhydroxy compounds, and melamine formaldehydes. The general use of intumescent FRs in polyolefins and other polymers is discussed in a book by Le Bras et al. From Wikipedia, The Free Encyclopedia Not to be confused with Trisodium phosphate. Another flame-retardant application using CNTs can be the development of flame-resistant coatings, as long as they show specific interaction with the binder. 23.15 (a)), which is typical of an intumescing system. These agents have excellent charring effect because they contain abundant nitrogen and possess a structure of tertiary nitrogen. Trends in formulating intumescent paints include the replacement of polyols with polymeric hydroxylic compounds, as well as their combination with nanoclays in order to increase the melt viscosity of the paint in case of fire and to reinforce the barrier effect of the coating against oil and fuel. Heat dissipation from flame-retardant (FR) PE/EVA materials (UL 94 V-0, 1.6 mm) [15]. Scheme 7. 25 in Table 9) was used as a macroinitiator for the polymerization of methacrylate monomers. 5 in Table 13) and functionalized with folic acid. Whereas dense black smoke is formed very rapidly with brominated or chlorinated FRs, the smoke density value for plastic containing an APP-based intumescent system (®Exolit AP 750) remains low for a long time. Laboratory Chemical Safety Summary (LCSS) Datasheet. Its chemical formula is [NH 4 PO 3] n (OH) 2 showing that each monomer consists of an orthophosphate radical of a phosphorus atom with three oxygens and one negative charge neutralized by an ammonium cation leaving two bonds free to polymerize. The resultant carbonaceous char is less flammable than before [16]. The esters decompose to release carbon dioxide and regenerate the phosphoric acid catalyst. Free samples program. Sodium Hexametaphosphate is also called as Calgon. In water treatment general orthophosphate and polyphosphate are used. With 22.5% APP and 7.5% PPTA V-0 was observed [23]. Sodium polyphosphate MSDS (material safety data sheet) or SDS, CoA and CoQ, dossiers, brochures and other available documents. In the case of polypropylene, a combination of CNTs with APP brings enhanced FR properties. It is basically the effect of that earlier starting decomposition in connection with water release that makes the intumescent blends more sensitive in processing than the APP alone.

We can assume that these needles could be the result of some kind of ‘crystallization’ of phosphoric acid coming from the degradation of APP at high temperature. 3 in Table 17) was functionalized with acrylate end groups and cross-linked. These nanogels (167) were synthesized for targeted antibiotic delivery to bacterial infection sites [500]. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. If ordinary phosphoric acid is heated, water is removed and the orthophosphate ions combine to form a polyphosphate. As they enhance the FR properties of the polymer, they can be considered synergist as FR properties are enhanced compared to a sample with the same loading of APP without this nanofiller. Recently, a new type of shell cross-linked micelle, fabricated by self-assembly of the multifunctional polymeric prodrug, was described. APP is reported to be biodegradable and could be used or regarded as a fertilizer, which makes it an attractive FR for bio-based polymers like PLA and biodegradable polymers. (Nifant’ev, I.E., Shlyakhtin, A.V., Bagrov, V.V., et al., 2017. In a 150-ml acid-washed beaker, dissolve the sample in 100 ml of deionized distilled water. Once the materials were extruded, two types of samples were produced: 12.5 × 130 × 3.2 mm3 bars produced via injection moulding (material temperature set at 270 °C, and mould temperature set at 40 °C) to study fire resistance via the UL94 test at 3.2 mm of thickness and perform SEM (scanning electron microscopy) observations on the surface of these samples (see Fig. We use cookies to help provide and enhance our service and tailor content and ads. Scheme 8. We can see a structure with lots of holes in the char layer formed on PP–APP blend (Fig. (Yuan, Y.-Y., Du, J.-Z., Song, W.-J., et al., 2012. Indeed, in this case, the PP–APP blend just reached V2 classification.

Contact Supplier … If the intumescent FR is dispersed in a polyolefin compound, the effect is much less drastic than with the pure powder blend but the more decomposition takes place during processing, the more negative effects will be observed. 23.14). 12.5 × 130 × 2 mm3 bars produced via compression moulding (190 °C, 150 bar) to study FR behaviour via the UL94 test at 2 mm of thickness and perform SEM observations on the surface of these samples (see Fig. Short and linear chain APPs (n < 100) are more water sensitive (hydrolysis) and less thermally stable than longer chain APPs (n >1000), which show a very low water solubility (< 0.1 g / 100 ml). The nanogel with a polyphosphate core cross-linked by many hydrophobic diselenide bonds and a hydrophilic PEG shell was obtained by using sodium diselenide as the crosslinking agent able to react with the MBS groups in copolymers [482]. Potassium pyrophosphate. Figure 7 shows data from measurements in a cone calorimeter, which again make clear the significant difference between a halogenated FR and an intumescent system. Two compounds were prepared, both by twin-screw extrusion following specific process parameters (screw profile, temperature profile), designed to achieve a high level of dispersion of carbon nanotubes. This process does not convert 100 percent of the orthophosphate ions into the polyphosphate form. 23.14 (a)), we can see small particles of APP spread quite homogeneously in the matrix. PO3]n. The properties of APP depend on the number of monomers in each molecule and the structure of the polymeric chains. PUBCHEM_16133246 Owing to the mode of action of APP (formation of a protective layer), only very little smoke is formed in the early stages of a fire, a fact that can give those involved extra time to escape or be rescued. Polyphosphate, Medium Chain (p100; biotinylated) Chemical Formula: Na n+2 P n O 3n +1 n = the average number of phosphorus (P) atoms in the chain Molecular Weight: Heterogeneous; Number average ~11.5 kDa; Range ~2 kDa to 28.5 kDa Format: Lyophilized Purity: 1% monophosphate 23.15).

The phosphoric acid acts as an acid catalyst in the dehydration of carbon-based polyalcohols, such as cellulose in wood. Sodium tripolyphosphate is an inorganic compound with formula Na5P3O10 and the sodium salt of the polyphosphate penta-anion. Read about company. Polyphosphates can have linear or cyclic ring structures. dipentaerythritol or sorbitol, are employed as synergists [16,17]. Mater. This is particularly true because the chemistry of orthophosphate and polyphosphate chemical additives is complex, and phosphate water treatment chemical Hoppe concluded that depolymerisation is the predominating model affecting phosphate glass structure.21, C. Dewaghe, ... P. Dubois, in Polymer–Carbon Nanotube Composites, 2011. A “soapy” surface on the polymer strands after running through a cooling bath and a high water content of the granules after compounding are very good indicators for partial decomposition during processing. Molecular Formula. The PP containing the intumescent system does not release any corrosive halogen hydrides and generates only insignificant amounts of toxic fumes such as HCN or NOx. The phosphoric acid reacts with alcohol groups to form heat-unstable phosphate esters. (Xiong, M.-H., Li, Y.-J., Bao, Y., et al., 2012. Scheme 8). FIGURE 4. This defect is eliminated by the presence of a real neighbour of modifying oxides. Commercial products differ in molecular weight, particle size, solubility, and surface coating.

In this model, it was assumed that all terminal oxygen atoms, including not only NBO in the Q2 middle unit but also DBO in the Q3 branching units, tend to coordinate with the metal oxides. Purity Requirements: , … In the polyphosphate region two possibilities can occur: firstly, at x = 0.67 the network is based on phosphate dimer, two Q1 tetrahedra units linked by one bridging oxygen, and is called a pyrophosphate unit; secondly, at x = 0.75, the network is based on isolated Q0 units1920, Another model that was proposed for the interaction between modifying oxides and the glass network is called ‘repolymerisation’.21 This model is applied for the glass in the ultraphosphate region, and is used to explain the packing density and M–O coordination number, where M refers to metal. Sample in accordance with Standard for Sodium Tri polyphosphate, AWWA B503-78, American Water Works Association, Denver, Colorado (1978). The release of heat from plastics components in a fire is also an important criterion, since the rate of flame spread depends quite fundamentally on this factor. The resulted structures were used as the carriers for the biologically active substances. The selection of a phosphate water treatment chemical additive can be one of the most difficult chemical treatment decisions that many public water systems will make. When the charring agent (8 wt%) and APP (22 wt%) were incorporated into polyethylene, the limiting oxygen index (LOI) reached the maximum of 31.2, and class V0 in the UL 94 test was obtained. Ammonium polyphosphate is an inorganic salt of polyphosphoric acid and ammonia.The chain length (n) of this polymeric compound is both variable and branched, and can be greater than 1 000.
