WebPolyether ether ketone ( PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. The polymer was first developed in November 1978, [2] later being introduced to the market by Victrex PLC, then Imperial Chemical Industries (ICI) in the early 1980s. [3]
WebThermosetting polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer ( resin ). [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. WebProperties of Polymers .
