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 .
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.
Figure 1: Representative Structure of Polyphenyl Ether (PPE) Figure 2: Representative Structure of Polyphenylene Oxide (PPO) Phenyl ether polymers are a class of polymers that contain a phenoxy or a thiophenoxy group as the repeating group in ether linkages.
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]
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.
The structure of the repeating unit of PPP Space-filling model of a short section of PPP. Poly(p-phenylene) (PPP) is made of repeating p-phenylene units, which act as the precursor to a conducting polymer of the rigid-rod polymer family.
The most used film materials are polypropylene, with a market share of 50%, followed by polyester, with a 40% share. The remaining 10% share is accounted for by the other dielectric materials, including polyphenylene sulfide and paper, with roughly 3% each. [23] [24]
Poly(p-phenylene vinylene) (PPV, or polyphenylene vinylene) is a conducting polymer of the rigid-rod polymer family. PPV is the only polymer of this type that can be processed into a highly ordered crystalline thin film.
