Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked by sulfides. Synthetic fiber and textiles derived from this polymer resist chemical and thermal attack. PPS is used in filter fabric for coal boilers , papermaking felts , electrical insulation , film capacitors , specialty membranes , gaskets , and packings .
PPSF is a moldable plastic often used in rapid prototyping and rapid manufacturing (direct digital manufacturing) applications.Polyphenylsulfone is heat and chemical-resistant suited for automotive, aerospace, and plumbing applications.
Three polysulfones are used industrially: polysulfone (PSU), polyethersulfone (PES/PESU) and polyphenylene sulfone (PPSU). They can be used in the temperature range from -100 to +200 °C and are used for electrical equipment, in vehicle construction and medical technology . [ 1 ]
Polyphenylene sulfide is a useful high temperature plastic. Coenzyme M, CH 3 SCH 2 CH 2 SO − 3, is the precursor to methane (i.e. natural gas) via the process of methanogenesis. Selected thioethers, from left: dimethylsulfide, coenzyme-M, the amino acid methionine, the vitamin biotin, and the engineering plastic polyphenylene sulfide.
Polyphenylene sulfide film capacitors are well-suited for applications in frequency-determining circuits and for high-temperature applications. Because of their good electrical properties, PPS film capacitors are an ideal replacement for polycarbonate film capacitors, whose production since 2000 has been largely discontinued.
Air Fresheners. Why they're a waste: The air-freshener industry continues to rake in the cash, and it's no wonder: Scented-oil refills for an outlet freshener can cost upward of $2.50 a pop, and ...
Poly(p-phenylene oxide) (PPO), poly(p-phenylene ether) (PPE), poly(oxy-2,6-dimethyl-1,4-phenylene), often referred to simply as polyphenylene oxide, is a high-temperature thermoplastic with the general formula (C 8 H 8 O) n. It is rarely used in its pure form due to difficulties in processing.
Polyphenylene sulfide (PPS) obtained by the condensation polymerization of p-dichlorobenzene and sodium sulfide, has outstanding chemical resistance, good electrical properties, excellent flame retardance, low coefficient of friction and high transparency to microwave radiation. PPS is principally used in coating applications.
