Pre - Dispersed 80% 1987 White Transparent Granule Activator For Footwear
Product description
Activator 1987/A , White transparent granule , Used for soles and other rubber products.
Recommendations and Applications:
Activator 1987 is able to decrease acidity of silica’s surface ,
reduce absorption of accelerator on the surface of silica ,
will significantly activate and help dispersion of silica and clay.
It also accelerate the vulcanization, increase rubber crosslinking, shorten curing time , improve
physical properties of the vulcanizates (e.g., tear strength, tensile modulus, hardness and elasticity).
Activator 1987 forms special crosslinking structure in the rubber ,
significantly prevent silica migrating onto the surface.
