Commercial phenyl ether polymers belong to two chemical classes: polyphenyl ethers (PPEs) and polyphenylene oxides (PPOs). RR121. It can also be formed by polymerisation of p-halothiophenoxide metal compounds both in the solid state and in solution, or by condensation of p-dichlorobenzene with elemental sulphur in the presence of sodium bicarbonate. Typical properties for Polyphenylene Sulfide (PPS) including physical, mechanical, … CONSTITUTION: An aromatic polyhalide containing pref. Density g/cm3 ISO 1183 1.66 Water absorption (23°C,24hrs,1mmt) % ISO 62 0.04 Melt viscosity (310 ,1000/sec)℃ Pa・s ISO 11443 260 Tensile strength MPa ISO 527-1,2 210 Strain at break % ISO 527-1,2 1.9 Flexural strength MPa ISO 178 290 Flexural modulus MPa ISO 178 14,000 Charpy notched impact strength (23 )℃ kJ/m2 ISO 179/1eA 11 Density (g/cm 3) 1.8. Polyphenylene sulfide (PPS) is a semi-crystalline engineering thermoplastic. B = Good -- Minor Effect, slight corrosion or discoloration. The chemical structure of PPS is as below: PPS is a high aryl-sulfur crystalline polymer with theoretical density of 1.44 g/cm3, the melting point of 250~315°C, the decomposition temperature of more than 480°C, volume resistivity of more than 1016 Ω. cm, oxygen index greater than 43%, flame retardance of UL94 V- 0, excellent heat resistance and electrical performance. It offers the broadest resistance to chemicals of any advanced engineering plastic. Ryton® PPS (polyphenylene sulfide) compounds offer a unique combination of properties and a cost/performance balance unmatched by other engineering thermoplastics: Thermal Stability : A remarkable combination of both long-term resistance to temperatures up to 200°C (392°F) and short-term resistance to temperatures up to 260°C (500° F) is supplier for Polyphenylene sulfide (PPS). Tensile Strength (MPa) 91. PPS (PolyPhenylene Sulfide) is a semi-crystalline engineering thermoplastic. PPS has outstanding mechanical properties and it is resistant to hot water and steam. Standard Polyphenylene Sulfide (PPS) Compounds. Density: 1183: kg/m 3: 1660: Water absorption rate (in water at 23°C 24 hrs.) For commercial purposes, PPS would be produced by the reaction of p-dichlorobenzene with sodium sulphide in a polar solvent.
Solvay S.A. We provide Polyvinylidene fluoride (PVDF) as well. Chemical Compatibility Plastic Material Chart for PA66, PEEK, PPS, PVDF and POM PA66 = polyamide 66 PEEK = polyetheretherketone PPS€€ = polyphenylene sulphide PVDF = Polyvinylidene fluoride POM = polyoximethylene acetal Ratings -- Chemical Effect A = Excellent. Surface Hardness. PURPOSE: To obtain a polyphenylene sulfide with high bulk density, easy to handle, by polymerization, in the presence of a sulfur source and amide-based solvent, of an aromatic polyhalide immediately followed by gradually cooling the system to make the polymer separate out in the form of granules of specific size. Polyphenylene sulfide (PPS) offers the best chemical resistance with no known solvents below 392°F (200°C). It consists of para-phenylene units alternating with sulfide … Select a product number from the table below to view a product data sheet for these materials using polyphenylene sulfide as the base resin.. 1399X numbered products are our proprietary formulations. PPS is a chemical and corrosion resistant plastic material that is often used in applications involving exposure to corrosive chemicals at elevated temperatures. There are no known solvents that effect PPS under 392º F, and it is inert to steam, strong bases, fuels, and acids. …
Solvay has a worldwide presence in 50 countries, over the 5 continents, with an expanded presence in Asia, the Americas and Eastern Europe.
it's low moisture absorption, good mechanical and excellent thermal resistance properties make PPS ideally suited for precise tolerance machined components. PPS can be prepared in a number of ways. Phenyl ether polymers are a class of polymers that contain a phenoxy or a thiophenoxy group as the repeating group in ether linkages.
Polyphenylene sulfide (PPS) is a semi crystalline, high temperature engineering thermoplastic.It is rigid and opaque polymer with a high melting point (280°C).
