High Quality PVB Inner Film Extrusion Machine

Product Description

Product introduction:
   Our production of PVB membrane is  composed of polyvinyl butyral and plasticizer resinified,mixed with other additives ,polymer materials by extrusion molding ,PVB membrane has a transparent heat-resistance ,cold membrane has a transparent,heat-resistance ,cold resistance,moisture resistance and high mechanical strength and other characteristics particular suitable for inorganic bonding of glass materials,production of laminated safely glass.
    Security glass is refer to two tables or more tables glass Middle joined PVB Middle film by composite ,heating and high pressure and made of special glass,laminated glass has anti-penetrating,noise,insulation,anti-UV,resistance high low temperature climate,special function,and PVB Middle film of reflective coefficient very close glass itself ,so laminated glass can keep General glass sames of pure and the transparent ,currently in car and the building field widely application ,for example car wind glass,building curtain wall.Bulletproof glass and the window ,has security requirements of places.
    We produced the PVB intermediate film thickness between 0.38-1.52mm,width of 550-3300mm.Our company uses the research technology roller and water method ,with these two methods we can recycle old material and save cost.At the same time it can produce high-quality products.
