TECHNICAL DATA
VAC-PAK^® HT-620 High Temperature Bagging Film
For Phenolics, Polyimide and Bismaleimide Systems

DESCRIPTION
VAC-PAK^® HT-620 is an olive colored high temperature, high elongation cast film produced from "PTFE" resin. VAC-PAK^® HT-620 can be used in cures up to 620°F (326°C). To ensure good adhesion to our sealant tapes, one side has been chemically conditioned.

APPLICATION
VAC-PAK^® HT-620 is recommended as a bagging film for advanced composite fabrication and other high-temperature / pressure applications where softness, workability, conformability and defect-free films are needed.
VAC-PAK^® HT-620 is designed for use with polyimide, bismaleimide and phenolic systems.
