Abstract

Baker Petrolite’s POLYMEKON® polymer and UNITHOX® ethoxylates, used alone and in combination with silicon oil, have shown to be effective when used at concentrations of at least 1 weight percent in unfilled as well as talc-filled thermoplastic polyolefins (TPOs).

Additives to improve scratch and mar resistance of polypropylene based resins

Improvements in scratch and mar resistance of polypropylene based resins have been achieved by incorporating additives developed, manufactured and marketed by Baker Petrolite.  Baker Petrolite’s POLYMEKON® polymer and UNITHOX®  ethoxylates, used alone and in combination with silicon oil,  have shown to be effective when used at concentrations of at least 1 weight percent in unfilled as well as talc-filled thermoplastic polyolefins (TPOs). 

Increased scratch and mar provides aesthetic benefits for molded TPO parts, particularly for use in interior automotive applications.

UNITHOX ethoxylates are high molecular weight, high melt point ethoxylated alcohols and are available in a range of molecular weights and ethylene oxide contents.  POLYMEKON polymer is a potassium salt of an oxidized hydrocarbon wax.
