Weatherability PVDF film for vacuum sealing materials

Weatherability PVDF film for vacuum sealing materials\

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. It can be widely used as the corrosion-resistant materials, abrasion-resistant materials, corrosion-resistant equipment linings, transparent viewing mirrors, vacuum sealing materials, electrical and electronic components, and motor or instrument parts, etc.

PVDF Main Properties:

 1). high tensile strength

 2). high mechanical strength

 3).high rigidity(also at low temperature)

 4).high chemcial resistance

 5). very low water absorption

 6). good firction and wear & tear values

 7). high UV-resistance

 8).toxic tumes when burned

 9).Excellent class A fire protection

 10).Aging resistance
