Product description
Parameters

This is a very low-adhesion film used as a secondary material to improve yield in film and foil processing. It has excellent dimensional stability and causes no heat-shrinkage damage to the adherent product even in high-temperature environments.  It also has strong chemical resistance.

 

Excellent dimensional stability in heating processes and a design that minimizes curling.

·   No adhesive deposit on the adherent product.

·   Silicon-free release film, so there is no risk of contamination.

·   Also has excellent chemical resistance and anti-scratch properties.

·   Can be easily peeled off after use thanks to its light-peel design.

·   Helps prevent wrinkles and folds in processing and improves production yield.

 

Protective films for preventing film/foil curling, wrinkling and foreign-matter adhesion while undergoing heating.

·   Carrier film for printed circuit board and flexible printed circuit board processes
