China Polyester Surface veils for pultrude profiles

Surfacing Veil are non-woven formed fabrics produced from polyester. It is produced for pultrusion process. Excellent resistance to oxidizing agents and are not degraded by bleaching treatments ordinarily used for textiles.Good resistance to aqueous solution of most weak acids at the boil and to aqueous solution of strong acids at room temperature, but are disintegrated by concentrated (95%) sulphuric acid at room temperatureGood resistance to aqueous solutions of strong alkalies at room temperature but are degraded by aqueous solutions of strong alkalies at the boil.
