Additive boosts scratch and mar/resistance in automotive TPO

Axel Plastics Research Laboratories announced the commercialization of MoldWiz INT-35CPD, a new additive designed to improve the scratch and mar performance in automotive-grade thermoplastic polyolefin (TPO) resins. The new additive has been documented to reduce scratching at additions as low as 1-2%, in which no scratching was evident at 10 newtons of force, and significantly less depth of scratching occurred at forces up to 20 newtons, thereby reducing light scattering and improving the visual appearance.

ASTM D7027-05 also validated the improvement in scratch reduction attained by addition of INT-35CPD. This test method demonstrated improvement values consistent with those observed in the Ford Five Finger tests.

While unrelated to its primary functionality, MoldWiz INT-35CPD can also reduce resin viscosity in extrusion and cut ejection force in injection molding by up to 3%. INT-35CPD is a proprietary synergistic blend of modified polymers and organic fatty amides. The additive is available as a 100% active pellet or as a free-flowing powder. Axel recommends the new additive for use in TPO, PP, and other polyolefins.

INT-35CPD is one of many products manufactured by Axel, a 66-year-old ISO 9001 registered, REACH-compliant manufacturer of proprietary mold releases and process aid additives.
