RECOMMENDATIONS FOR APPLICATION
STRUKTOL® WB 212 is a processing additive for rubber polymers which is normally used to improve the general compound processing without significant influence on the physical properties. It acts as a dispersing agent for powdered materials and can shorten the mixing time by faster filler incorporation. STRUKTOL® WB 212 prevents sticking of elastomers and compounds to rotors and rolls. The addition of STRUKTOL® WB 212 can reduce the risk of scorching, particularly in highly loaded compounds. Due to the good plasticizing properties of STRUKTOL® WB 212, molds can be filled faster with lower pressures during injection and transfer molding. Mold release is improved. The effect on the vulcanization behavior is neutral; this applies also to peroxide cure systems. The water content of STRUKTOL® WB 212 may cause a slight activation in compounds based on chlorosulfonated polyethylenes or equivalent polymers.
