PET (Polyethylene terephthalate) Product Guide
Applications | Mechanical and Chemical Data
Overview
PET is a general-purpose thermoplastic polymer which belongs to the polyester family. Its a strong, stiff engineering plastic with excellent clarity, bearing and wearing properties, and chemical resistance. PET is virtually odorless and thermoforms easily at low forming temperatures with quick cycle times. PET is also known for its shatter resistance, low moisture resistance, stain resistance, and low thermal expansion. Its typcially used for food processing machinery components, filler pistons, graphic arts, clear novelty items, and wear pads.
