What fields are pet sheets used in?

The components of PET sheet mainly include polyethylene terephthalate pet and polybutylene terephthalate PBT. Polyethylene terephthalate is also commonly known as polyester resin, commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol. Together with PBT, it is collectively referred to as thermoplastic polyester or saturated polyester. Pet and PBT, together as thermoplastic polyester, have become one of the five engineering plastics.

1. Main characteristics of PET sheet:

High mechanical strength, rigidity and hardness. Good sliding performance and wear resistance, good electrical insulation, very good creep resistance, low and stable friction coefficient, excellent wear resistance (better than nylon), very good dimensional stability (better than POM), physiological inertia (suitable for contact with food). Weather resistance, good stability against chemicals, low water absorption, resistance to weak acids and organic solvents, but not resistance to hot water immersion and alkali.

2. Application fields of PET sheet:

It is widely used in textile, papermaking, food machinery, transportation, wharf, medical treatment, coal mine, chemical industry and other industries. Bearings, guide food processing machine heads, pistons, screw rolls and other food fixtures, parts, bearings of precision machines, electrical insulation materials, etc.
