Detailed Product Description

PVDF film, PVDF transparent film

PVDF (polyvinylidene fluoride) is a kind of light fluoride material, with the working temperature ranging from -70 to 150 . It features superior corrosion resistance, mechanical property, electrical insulating property, low friction coefficient, weatherability, and radiation tolerance. Moreover, the tensile strength is two times higher than PTFE, the compressive strength six times higher than PTFE, and the abrasion resistance similar to nylon.

Properties

Color:white ,transparent

Surface :Mat , coronatreated

- Perfect weather fastness and UVioresistance aging ,over 3000hours long life

- Perfect flat film surface ,easy for second progress.
- Lower moisture transmittance
- outstanding bond&compound property ,especially good compound effect with PET film,sheet. And EVA film .

- Perfect mechanical property ,especially tearing strength of transverse and portrait .

- High cost performance

Application:

Usage

Photovoltaic industry:Solar cell backsheet film.

Interior decoration : inner decoration of Automobile,train,aircraft etc.

Electrical apparatus insulation:In electrical field, it can replacePC,PET,PP etc traditional materials.
