Baerolub Zincum SW/F

Baerolub Zincum SW/F by Baerlocher is zinc stearate. Acts as a lubricant. It is a polar hydrocarbon that provides external lubrication which in turn is influenced by the length of hydrocarbon chain, branching and functional groups present. Reduces wall adhesion between PVC (polyvinyl chloride) and metal surfaces. Baerolub Zincum SW/F increases fusion time, decreases torque, improves surface gloss and reduces melt viscosity. Suitable for sidings, gutters and rigid extrusion. Transparency and high dosages cause over-lubrication leading to haziness and exudation.
