Polyethylene terephthalate is a polymer with properties close to the polyacetal. Bearing type material with exceptional self-lubricating properties and friction coefficient significantly lower than polyamides and polyacetal. The disadvantage of PET is its brittleness and weak impact resistance. Applications: The main advantages of PET are in medical and pharmaceutical equipment. PET parts with up to 1000 sterilization cycles, X-rays, physiologically inert. PETs are made of handles of most medical instruments, sleeves in mobile hospital beds, used as a slider for opening and closing of moving bridges.
The material is FDA-certified for nutrition. Modified variant of PET with teflon (Sustadur® PET GLD 130). ECTFE (ethylene chlorotrifluoroethylene) Fluorocarbon polymer based on ethylene and chlorotrifluoroethylene. Resistant to friction, chemical effects, temperature.
