HS-8171 6/66


HS-8171-6/66 Co-Ex is a blue-green-tinted, transparent, heat-stabilized, co-extruded copolymer film produced from a modified nylon 6/66 resin. HS-8171-6/66 Co-Ex is a high temperature nylon film which can be used for cures up to 420°F (215°C). It will remain pliable and not become brittle after long extended cure cycles. It is available as lay-flat tubing and as lay-flat sheet. Standard thickness is .002 or .003 inches. Any non-standard width is available up to 160 inches.


HS-8171-6/66 Co-Ex is recommended as a bagging film for advanced composite fabrication and other high-temperature / pressure applications where softness, workability, pinhole-free and defect-free films are essential. The co-extrusion process represents the most advanced “state-of-the-art” in blown film production. This is achieved because of the multiple flow of film fusing together at the extrusion die exit.
