BOPP capacitor film

(1)BOPP hazy film for UHV (both sides rough surface):

The film has the character of low dissipation factor,high dielectric strength, good compatibility with various impregnation dielectric oils.The capacitor made by this kind of film is applied to HV, EHV and UHV power transmission application field.

Thickness: 8-16μm 

(2)BOPP ultra thin plain film:

The filmhas the character of ultra thin property(≤3.5μm), low heat shrinkage rate and high temperature resistance. Mainly used in LED light, electric and hybrid vehicle field etc.

Thickness: 2.0-3.5 μm 

(3)BOPP Hazy film for high voltage medium-frequency induction furnace(both sides rough surface):

The film has the character of good winding and good high voltage resistance etc. The capacitor made by this kind of film is applied to medium-frequency induction furnace steel making field.

Thickness：6-25μm 

(4)BOPP hazy film for high voltage microwave oven (one side rough surface):

The film has the character of good winding. Through the the compatibility test of film and impregnant, aging test and tensile property test, completely conform to the requirement of the microwave capacitor hazy film media. The capacitor made by this kind of film is applied to household appliance , e.g microwave oven, etc.

Thickness: 11-18μm 

(5)Plain Bopp film (MPP)

The film has the character of good thickness uniformity, high mechanical strength and superior electrical properties,etc. The capacitor made by this kind of film is applied to home appliances, pumps, low voltage electric control, etc.

Thickness: 3.8-18μm 

(6)BOPP High temperature resistance film(H-MPP)

The film has the character of good thickness uniformity, low dielectric loss, high insulation resistance, high dielectric strength. The capacitor made by this kind of film is applied  to LED light, special motor, wind power, solar power, high speed locomotive, etc.

Thickness: 3.9- 9.8μm 

(7)BOPP Metalized film

The product is aluminized by aluminum and zinc. The capacitor made by this product is with good oxidation resistance, and good self-healing function.
