PVB Interlayer Film PVB Heat Insulation Film Special Function
Product introduction:
PVB interlayer film is a translucent or opaque film.It is a kind of polymer material plasticized andextruded by polyvinyl butyral resin with plasticizer.The appearance is translucent or opaque film, freeof impurities, flat surface, certain roughness andgood softness It has good adhesion to inorganicglass and has the characteristics of transparency,heat resistance, cold resistance, moisture resistanceand high mechanical strength. It is the best bondingmaterial for manufacturing interlayer and safetyglass in the world. At the same time, it is also widelyused in architectural fields such as building curtain wall, window, bank counter, prison visiting window, steel furnace screen and various bulletproof glass.

Note:
1. Measurement under conditions of Colorless glass (2mm) + interlayer film (0.38mm) + Colorless glass(2mm).
2. Measurement under conditions of 20℃ and 40% relative humidity.
3. It is be able to adjust according to cusomers' requirements.
4. Measurement after 15 minutes under the conditions of 60℃ and 40% relative hunmidity.
5. The date of interlayer film of HI (Automotive windshields) and ST (Architectural glass) are different,both samples should be tested with -18℃ after 1 hours.
