Zhejiang Ligao Insulation Material Co., Ltd.
Milky polyester film PET film
Polyester film is a film material made of polyzhexyl glycolic glycol ester as raw materials. The thin film material made of squeezing method, and then stretched by two -way stretch.
It is a colorless, shiny film, with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature and low temperature.
It is one of the commonly used obstructive composite film substrates.

Have the following advantages:
1. heat resistance, water -resistant, chemical resistance. Molicine 260 degrees Celsius.
2. Concentrated size. With excellent mass halo quality.
3. The membrane surface is smooth and uniform, adhesive and electrification prevention characteristics.
4. The transparency is very superior. The light transmission is 90%, and the thickness increases. The light transmittability is almost unchanged.
Products are mainly applicable to: electronics, printing, packaging, packaging, insulation, soft line printing, showing device screen guarantee PET, film switch, thin film window, printing film, packed plate base, non -gum bottom paper, glue, silicon, motor, motor, motor, motor Cushion, cable belt, instrument panel, capacitor insulation, IMD mobile phone case, etc.
