Polyvinyl Acetate for BMC anti-shrinkage formular

The BMC-used 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.

PVAC NO#: : PVAC10
Molecular Weight: : 350,000g/mol - 550,000g/mol
Viscosity: : 33.0-35.0

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.
