White Mineral Oil A New Way to Lubricate Rigid PVC

摘要

Processors of rigid PVC pipe, window profiles, siding, fencing, and doors can save money and speed compound mixing by using a new grade of white mineral oil as an external lubricant in place of the usual paraffin wax. That's the world from Crompton Corp., Greenwith, Conn., whose Hydrobrite PVC Oil is a highly refined, free-flowing liquid paraffin that reportedly does not agglomerate in storage or handling as is typical of orwax. The liquid form is also said ot result in more uniform coating of PVC particles and improved productivity in high-intensity mixers.
