PPS Materials (Polyphenylene Sulfide)
PPS Materials (Polyphenylene Sulfide) PPS is used in filter fabrics for coal boilers, papermaking felts, electrical insulation, film capacitors, special membranes, gaskets and packing. PPS is a precursor to a conductive polymer of the semi-flexible rod polymer family. Polyphenylene sulfide is an engineering plastic which is mainly used now as a high performance thermoplastics. PPS is marketed by Petron Thermoplast Manufacturer in India. This is one of the best company for Engineering Plastics. The synthesis of PPS has established challenges. It has been achieved via extra polycondensation with the Suzuki coupling method.
Early efforts commonly produced black, insoluble powders that have been hard to characterize. For example 1962 paper reports “The strong glowed red-warm in a Bunsen flame, and not using a proof of flame formation, and disappeared most effective slowly.” Initially, the material’s chemical and thermal stability piqued curiosity in its synthesis. PPS Materials was utilised in rocket nozzles and textiles that needed to be thermally stable.
PPS IS WIDELY USED FOR:
- Semiconductor machinery components
