WF330 is a non woven polyester felt widely used in vacuum bagging process for cures in oven and autoclave up to 205℃（401 ℉）and 7 bars max.
This medium weight allows to breath air out from the vacuum bag and bleed excess of resin. In case of large excess of resin two or more plies could be used. WF330 is the result of Leadgo’s R&D research and specific fiber used makes this breather one of the best in the market.
Always use a release film between the part and WF330.
