--Pvb Film--
Polyinyl butyral film is made from PVB resin with plasticizer and prepared by the technology of extrusion and calendaring. I t can be used as the inner layer of sandwich safety glass of cars, locomotive, airplane, tanker, naval vessel etc. It can also be used as solid adhesive for safety glass, safety mask, building glazing, composite steel plate, etc. It conforms to the enterprise standard of Q/GHAD 18-2008.
