Description

MR release films can take temperature up to 315°C (600°F). These films have a high elongation and a good conformability. They work well with our high temperature sealant tapes. This film will provide a smooth surface after the cure. MR1 release film is offered in 25 µm (0.001 inch) thickness and MR2 release film is offered in 50 µm (0.002 inch) thickness. All standard perforations are available. Please see our perforation table in this section.

Benefits

• Softness of film reduces wrinkle marks on parts, improving surface finish and reducing hand finishing.
• Excellent release from cured parts, film comes off easily and leaves a glossy finish.
• Good elongation reduces bridging in corners, resulting in less rework on resin rich corners.
