MAGNUM SLG (super low gloss) ABS resin has demonstrated an ability to achieve equivalent or lower gloss levels in textured parts when compared to commonly used polypropylene (PP) products. It provides superior scratch and mar resistance and an improved flow and impact balance. Together with high stiffness over a wide temperature range, these properties enable the production of thinner-walled parts, which results in reduced weight, one of the most requested deliverables of the automotive industry.

New MAGNUM SLG ABS resin from Dow Automotive was developed as a mass ABS, a production process known for its unique consistent material properties and its commercial competitiveness. This proprietary mass process helps keep production costs down and eliminates the need for processing aids. As a result, MAGNUM SLG ABS resin delivers outstanding lot-to-lot consistency, giving processors a wider range of appearance options without compromising color tolerances.

ABS is typically characterized by its superior impact resistance, stiffness over a wide temperature range, and excellent scratch and mar properties. It is often used for interior applications because of its durability and long lasting aesthetic effects. The major disadvantage of traditional ABS is an undesirable high gloss level, even in molded-in textured parts. To compensate for the high gloss level, ABS parts are usually painted, or polypropylene (PP) is used as an alternative material. Painting ABS parts usually means high additional application costs, while PP is known for its poor scratch and mar resistance.

Previous attempts to develop low gloss ABS were achieved through adding production steps and/or other resins. This has typically led to expensive material and/or production modifications. MAGNUM SLG ABS resin overcomes these hurdles to deliver cost and performance benefits.
