The woven bleeders and breather fabrics are generally linked to a PTFE coated glass scrim (see the part PTFE). This fabric has a porosity allowing good air flow, especially in autoclave. This is a non inflammable product which can be used in high temperature cycles (700°C). This bleeder is recommended for the vacuum technology with prepregs in autoclave.
