PET sheet is the abbreviation of English Polyethylene terephthalate, referred to as PET sheet or PETP sheet. The Chinese meaning is: polyterephthalic acid plastic, referred to as polyester board.

　　 ingredients 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 polycondensate of terephthalic acid and ethylene glycol, collectively referred to as thermoplastic polyester or saturated polyester together with PBT. At present, PET and PBT together are used as thermoplastic polyesters and become one of the five major engineering plastics.

　　PET sheet

　　'S main characteristics:

　　 High mechanical strength, rigidity and hardness. Good sliding performance and abrasion resistance, good electrical insulation, very good creep resistance, low and stable friction coefficient, excellent abrasion resistance (better compared to nylon), and very good dimensional stability (better than POM), physiologically inert (suitable for contact with food). Weather resistance, chemical resistance, good stability, low water absorption, resistance to weak acids and organic solvents, but not immersed in hot water and alkali.

　　 Application areas of PET sheet:

　　 is widely used in textile, paper, food machinery, transportation, wharf, medical, coal, chemical and other industries. Bearings, guides, food processing machine heads, pistons, screw rolls and other food fixtures, parts, precision machine bearings, electrical insulating materials, etc.
