Impact modified TPO release.

MoldWiz INT-33CRS process aid additive is said to have proven effective at improving release of impact modified TPO, while maintaining paintability and consistent surface gloss of the molded parts. INT-33CRS has been employed for improved release in the production of interior and exterior automotive trim panel. In these applications, 40% talc filled, high flexural modulus parts are said to have achieved excellent release by incorporating 0.3% of INT-33CRS. Exterior parts produced with MoldWiz INT-33CRS were still easily paintable, according to the company. And the unpainted interior parts are said to have maintained a consistent matte surface in post-production auto/ truck cabin simulation tests that were conducted by the manufacturer. Poor release of these YPOs is said to correlate directly to their higher rubber content, and this is where INT-33CRS can really improve processing, according to the company. INT-33CRS is a proprietary complex mixture of saturated and unsaturated fatty esters and modified organic acid derivatives. The product is available as a powder or a 100% active pellet. The maker of INT-33CRS is an ISO 9001 registered company that manufactures proprietary mold releases and process aid additives. All of the company's products are formulated from raw materials that comply with the chemical substance inventory lists of TSCA, DSL, MITI, EINECS, Australia and Korea.
