Stuktol® WB 212

Zinc-free blend of high molecular weight aliphatic fatty acid esters, inert condensation and loading products that improves the processing properties of the compound without affecting the physical properties. It acts as a dispersant of powder materials and accelerates their incorporation, reducing mixing time. Prevents the adhesion of the compound to rotors and rollers, as well as the risk of scorch of highly loaded compounds. Being also plasticizer, the mold can be filled faster at lower pressures during injection or transfer molding, it also helps to demold easily. It has no effect on vulcanization even if the system uses peroxides but may cause a slight activation of the process in chlorosulfonated compounds.
