Application Field Of PET Film

- Jan 05, 2019-

Polyethylene terephthalate

English name: polyethylene terephthalate, referred to as PET.

PET is a milky white or light yellow, highly crystalline polymer with a smooth, shiny surface. Excellent physical and mechanical properties in a wide temperature range, long-term use temperature up to 120 ° C, excellent electrical insulation, even at high temperature and high frequency, its electrical performance is still good, but poor corona resistance, resistance Creep resistance, fatigue resistance, abrasion resistance, and dimensional stability are all good.


Application areas:

PET film products are mainly used for: keyboard membrane switch, nameplate (silk screen) printing film, film window, electronic toy film circuit, flexible circuit board printing, FPCB flexible circuit board consumables, thermal transfer printing, bronzing, sound film diaphragm , plastic, imprinting base, self-adhesive backing paper, rubber coating, silicon coating, motor gasket, wire and cable belt, dance blanket conductive carbon film, electronic whiteboard film, instrument panel, capacitor barrier, card film, capacitor film, Food packaging, furniture stripping, thermal insulation, X-ray film and magnetic materials such as recording and video tape, vacuum aluminum plating, photoelectric backlight diffusion, reflection, brightness enhancement, concentrating, polarizing, fluorescent, EL luminescent film, mobile phone, LCD Display, luminous products, optical touch screen, LCD, LED, DVD screen protection, light box advertising, lampshades, signage nameplates, network communication products, digital products and various silk screen services.


PET is classified into fiber grade polyester chips and non-fibrous polyester chips. 1 Fiber-grade polyester is used to manufacture polyester staple fiber and polyester filament. It is a raw material for processing fiber and related products of polyester fiber enterprises. Polyester is the largest variety of chemical fiber. 2 Non-fibrous polyesters are also used in bottles, films, etc., and are widely used in the packaging industry, electronic appliances, medical and health, construction, automotive and other fields. Among them, packaging is the largest non-fiber application market for polyester, and it is also the most PET growth. Fast field.
