VAP one way ventilation membrane

Unidirectional permeable membrane is a kind of material that can block resin and allow gas to pass through. The product is composed of demoulding cloth and semi permeable membrane. It is used in "vacuum resin introduction" process, "wet vacuum bag forming process (prepreg or hand paste)". The unidirectional permeable membrane can continuously extract air and volatiles to prevent the loss of resin in the deposit. In order to make the solidified product easy to demould, the semi permeable membrane of the unidirectional permeable membrane can face the glass fiber laminated layer, but it should not be used as demoulding cloth.
