Polyvinyl Acetate (PVAC) for SMC/BMC. The polyvinyl acetate. It has the funtion of anti-shrinkage, surface brightness enhancement, strength increasing etc. The BMC usage PVAc is of much higher Molecular weight than SMC. As the Low profile additive, high viscosity PVAc provides a better treatment on the surface of BMC Compounds. The PVAC10 is largely used in BMC anti-shrinkage applications.
