Airweave® UHT 800 is a non-woven blended, fiberglass breather. It is safer to use this breather in place of a woven fiberglass breather. Airweave® UHT 800 makes an easier transition for the vacuum bag and in any radius. One layer provides good breathing to 800°F (427°C). Airweave® UHT 800 is designed for use with high temperature thermoset and thermoplastic resin systems.
