compound promoter for rubber processing
Pre-dispersed R-80/SBR
Composition:
80% Resorcinol
20% Butadiene styrene rubber and Surfactants & Dispersants
Appearance:
White or Bronzing granule
Density:
1.20 g / cm3(20°C)
Physiological Property:
take reference of safety date
Technology:
Pre-dispersed R-80 is one of the components from the composition of the Resorcinol,formaldehyde and white carbon black.It will form the Resorcinol-formaldehyde-resin system by the adhesion from rubber and fabric or all-steel cord which produced by the mixed together with formaldehyde offer(such as HEXA-80 or RA-65) during producing.This system is suitable for rubber and stiffener,such as the adhesion between fiber/glass fiber and metal(such as all-steel cord)
Process:
Generally, thin crystals resorcinol tends to bond with equipment and hard to disperse during mixing process.Pre-dispersed R-80 can solve this problem.
1.It pre-disperses within it's carrier styrene butadiene rubber(SBR) to make the material mixing easier.
2.Not becoming solid put in the normal environment
3.Good flowing character & non dust flying
4.Non wastage of feeding
5.Makes feeding more convenient and dispersed evenly to keep the best activity of resorcinol.
It is suggested feeding at the end of mixing.
