PEEK PE POM PC

image	type	brief product description
	PEEK other style	Polyetheretherketone (PEEK), also referred to as polyketones, is obtained from aromatic dihalides and bisphenolate salts by nucleophilic substitution. The bisphenolate salt is formed in situ from bisphenol and either added sodium or added alkali metal carbonate or hydroxide, by the Williamson ether synthesis. The aromatic dihalides are obtained from the 4,4’-Dihydroxybenzophenone.
	PE other brand	Polyethylene or polythene (IUPAC name poly(ethene)) is a thermoplastic commodity heavily used in consumer products (notably the plastic shopping bag). Over 60 million tons of the material are produced worldwide every year.DescriptionPolyethylene is a polymer consisting of long chains of the monomer ethylene (IUPAC name ethene). The recommended scientific name polyethene is systematically derived from the scientific name of the monomer.[1][2] In certain circumstances it is useful to use a structu
	POM other brand	Polyoxymethylene (POM), in the USA also commonly known under DuPont's brand name Delrin, is an engineering plastic, a polymer with the chemical formula -(-O-CH2-)n-. It is often marketed and used as a metal substitute. Delrin is a lightweight, low-friction, and wear-resistant thermoplastic with good physical and processing properties and capable of operating in temperatures in excess of 90 degrees celsius (approximately 200 degrees fahrenheit). According to the material safety data sheet from Du
	PC other brand	Polycarbonates are a particular group of thermoplastic polymers. They are easily worked, moulded, and thermoformed; as such, these plastics are very widely used in the modern chemical industry. Their interesting features (temperature resistance, impact resistance and optical properties) position them between commodity plastics and engineering plastics. Its plastic identification code is 7.
