Product Description

6021 Insulation/polyester film
Polyester film Offers an excellent combination of properties including low coefficient of friction, excellent lamination, good shape retention and spring effect, and high dielectric strength.
This product is widely used for electrical insulation in the motor industry.
The specification: 
Thickness(mm): 0.125mm, 0.188mm 0.25mm, 0.30mm, 0.35mm
Width:1m     Form: in rolls
Pacage: Carton     Storage life---1 year
Toughness: It doesnot crack or split when creased sharply. It is easily formed into "cuffed" slot liners and closures by semi-automatic machines and runs efficiently in fully automatic forming and inserting machines.
Insulation resistance: the electrical properties are excellent with a high level of insulation resistance and very low level of moisture absorption. Ideally recommended for slot liners .
Ageing: accelerated ageing tests at very high temperatures indicated that the life is longer than gerneral grades of polyester film
Chemical compatibility: It is compatible with most impregnating varnishes, partifularly thosed based on polyester resins of the isophthalate types.
