Polyethylene Terephtalate (PET) is available in sheet and rod form from Allplastics Engineering . It is one of the hardest industrial plastics and exhibits mechanical and creep strength, together with low thermal expansion, good sliding properties and high dimensional stability as it is virtually unaffected by ambient moisture.
PET is recommended for uses with close-tolerance, precision moving parts which require relative low friction and are subject to sustained high loadings and wear.
PET (Polyester) can be glued, is nontoxic and has FDA approval.
PET is available in a range of brands including Ertalyte and Ertalyte TX (self lubricatred). Used application where Acetal’s micro porosity in the centerline is not desirable.
Temperature rating: up to 100°C, 160°C short term
PET is suitable for structural applications, gears, distribution valves, friction strips, dynamic seals, bushes, packaging machinery parts, bearings and rollers. Medical components Mandrels, liquid and gas proof parts. It is available in white, black or grey.
