Basic formula

PP/PE, maleic anhydride (MAH), DCP, Acetone and other additives.

Application

Coupling agent for the compounding of PP with glass/carbon/wood fibres and mineral powders etc.

Compatibilisers for alloy compounding, e.g. PP/PA6, ABS/PA6, PA/EDPM.

Process

A polymer loss-in-weight feeder.

MAH and DCP are added to the solvent acetone and stirred with a stirrer. A loss-in-weight feeder is used to mix the liquid.

A good vacuum system is required for degassing.

Water-cooled strand pelletizing.
