colored glass film,
glass laminate film
polyvinyl butyral sheet (PVB film) is used as interlayer film in production of laminated safety glass for Automotive front glass and buildings; And potential costumers of PVB Films are glass factories. The PVB film is a high molecular polymer made from PVB resin and plasticizer, together With different additives according to different application and formed through Plasticization and extrusion by extruder. It is semitransparent, elastic, flat, without Impurity but with some roughness.
Use laminated glass can make car more safe and better sound insulation.
Automotive PVB Film Paraments:
Heat shrinkage rate(%):<=8.0
Pummel value,rank: 3~7
Visible light transmittance(%): >=80
Tensile strength(MPa): >=20
Tensile elongation(%): >=200
Yellowness index(%): <=10
Every layer of PVB film rolls should be sepatared by PE film and vacuumed by aluminum foil,and put into wooden case.
