Huakai, as a professional polyvinyl butyral (PVB) interlayer supplier, can produce automotive, photovoltaic grade, construction grade full range of film products. 

For the renewable energy sector growing photovoltaic market demand, focusing on the development Huakai PVB used in special folders film photovoltaic products. Our PVB films are with high transparency, high strength and excellent heat absorption, UV protection, moisture and other characteristics. They still have a high degree of reliability in the harsh outdoor weather conditions prolonged exposure.
