WF150 is a light non woven felt Polyester bleeder & breather fabrics, widely used in low temperature and middle temperature during debulking/compaction cycles under vacuum only.
WF150 helps to breath air outside the vacuum bag and volatile. Its low weight limits its use as both breather and bleeder functions as the same time. Some trials must be performed in such case prior to select this product.
WF150 should not be used at neither at high temperature nor high pressure.
Always use a release film between the part and WF150.
