Silicone Coated PET Release Film


LR-MR 20 Silicone Coated PET Release Film (equivalent to Mylar® HR951, Hostaphan 2MRK, PPI 0501 Mylar® HR951, Hostaphan 2MRK, PPI 0501) is made of PET Film coated with silicone release material on one or both sides. The coating layer is equable, has no wrinkle, avulsion, granule, pinhole or air bubble. Since the silicone is highly cured, there will be essentially no migration of the silicone to any adhesive which may be in contact with the film. This product provides excellent slip, low release force, and good dimensional stability over a wide temperature range.


Silicone Coated Polyester Release Film is widely used in:

·Electric: inter-liner for molding of insulation parts

·Electronic: release film used in the lay-up of multi-layer PCB

·Adhesive: inter-liner used for adhesive tape manufacturing

·Plastics: inter-liner for the production of sheets from casting compounds

·Roofing felt: covering and protection film for the adhesive part

·Bitumen: covering and protection film for pipeline wrapping tapes

·Rubber: inter-liner to prevent blocking(self-bonding) of rubber sheeting
