MIN-U-SIL® 5 GROUND SILICA CAS# 14808-60-7

MIN-U-SIL® 5 is a natural, fine ground silica with high purity.  The consistent pH and narrow size distribution of MIN-U-SIL® 5 allows very high loading with minimal effect on viscosity and cure rate.  MIN-U-SIL® 5 is inert, and offers increased shore durometer, reduced shrinkage, improved thermal conductivity, increased density, improved oil resistance, and high dielectric strength.
