Polyphenylene sulfide (PPS) is a semi-crystalline engineering thermoplastic. … It offers the broadest resistance to chemicals of any advanced engineering plastic. 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. Typical properties for Polyphenylene Sulfide (PPS) including physical, mechanical, … Polyphenylene sulfide (PPS) offers the best chemical resistance with no known solvents below 392°F (200°C).
CONSTITUTION: An aromatic polyhalide containing pref. Tensile Strength (MPa) 91. 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) Standard Polyphenylene Sulfide (PPS) Compounds. Density: 1183: kg/m 3: 1660: Water absorption rate (in water at 23°C 24 hrs.) Solvay has a worldwide presence in 50 countries, over the 5 continents, with an expanded presence in Asia, the Americas and Eastern Europe.
Density (g/cm 3) 1.8. Commercial phenyl ether polymers belong to two chemical classes: polyphenyl ethers (PPEs) and polyphenylene oxides (PPOs). Phenyl ether polymers are a class of polymers that contain a phenoxy or a thiophenoxy group as the repeating group in ether linkages. 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. It consists of para-phenylene units alternating with sulfide … 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. PPS is a chemical and corrosion resistant plastic material that is often used in applications involving exposure to corrosive chemicals at elevated temperatures.
PPS has outstanding mechanical properties and it is resistant to hot water and steam. PPS can be prepared in a number of ways. There are no known solvents that effect PPS under 392º F, and it is inert to steam, strong bases, fuels, and acids. For commercial purposes, PPS would be produced by the reaction of p-dichlorobenzene with sodium sulphide in a polar solvent. B = Good -- Minor Effect, slight corrosion or discoloration.
