Brand Name: BAEROLUB series

External lubricants mainly reduce wall adhesion between PVC and metal surfaces. Most of them are non-polar substances, such as paraffins or polyethylene. The external lubrication is influenced by the length of the hydrocarbon chain, the branching or the functional groups. In high dosages “over- lubrication” can lead to haziness and exudation. External lubricants increase the fusion time.
