Struktol® WB 222

Zinc-free mixture of high molecular weight aliphatic fatty acid esters free of water and condensation products that improves the processing properties of the compound without affecting the powder ingredients but that decreases the mixing time since it favors its incorporation. It prevents the adhesion of the compound to rotors and rollers, in addition to the risk of scorch in highly loaded compounds. Being also plasticizer, it allows a faster filling of the mold at lower pressures during injection or transfer molding, it also helps to demold easily. It considerably improves the dispersion of loads, fluidity and release during the processing, especially of nitrile compounds.
