Ester of montanic acids

Licolub® WE 4 powder

Licolub WE 4 powder is an ester of montanic acids with a polyol. Due to its polar center and the long, non-polar hydrocarbon chains, Licolub WE 4 powder combines internal and primarily external lubrication effects in the processing of engineering resins and PVC, especially in Polyester compounds.
In calendering of rigid PVC films Licolub WE 4 powder offers excellent lubrication properties at high thermal stability and low volatility.
