Description

PET is a general-purpose thermoplastic polymer that belongs to the polyester family of polymers. Known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability, polyester resins are suitable for extruded applications that require clarity, toughness and consistent processing performance. PET can be alloyed and compounded with engineering resins. Polyester resins are low cost, withstand temperatures up to 80˚C, offer good wetting to glass fibers, have a relatively low shrinkage of 4% ̶ 8% during curing, and provide a linear expansion ranging from 100 - 200 x 10-6 K-1.
