The Vacuum Bags Strips consist of a high-performance sealing butyl rubber compound.
Depending from the service temperature, the compounds available are:
VT RT for low temperature molding (debulking process);
VT 110 for medium temperature cure cycles up to 110 °C;
Yellow Vac for high temperature cure cycles up to 200 °C;
WT 205 for high temperature cure cycles up to 220 °C.
CharacteristicsEasy to apply;
Ideal for oven and autoclave curing;
Excellent release from tools leaving no residue;
Uses include: debulking / compacting, envelope bagging, resin damming or as a pressure strip;
Mantains adhesion during low temperature cycles;
Good adhesion to various films and tool surfaces;
UsesThese preform tapes have been designed for sealing in both “bag to tool” and “bag to bag” applications in ovens and autoclaves.
With aggressive initial tack, the Vacuum Bags Strips mantain an air-tight seal during the cure cycle and the tool clean from the strip, with virtually no trace of residue.
They provide easy de-bagging and minimal or no clean-up between production cycles.
