Solar control of automotive glazing appears to be a global trend because of passenger comfort and lower fuel consumption due to the vehicle's air conditioning (A/C). This can help smaller eco-cars to carry smaller and lighter A/C units. Current technology provides metal-coated glass and heat reflective PET film laminated with PVB film. However, in order to achieve the solar control function, a big investment is required and processability in glass lamination or glass handling is not easy. Therefore, manufacturing a solar control glass system is costly, with a low yield. The new PVB film with IRA cut-off function offered by Sekisui Chemical Co Ltd. can solve these problems. The company's special grade S-lec film PVB interlayer contains ultra-fine particles that effectively reduce incoming IR rays through laminated windows.
