A. Schulman Diamond Centrex® 485 Sheet Extrusion Grade  (discontinued **)
Categories: Polymer; Thermoplastic; ASA Polymer
Material Notes: Centrex 485 resin is a low-gloss, medium-impact grade of ASA (acrylonitrile-styrene-acrylate) with good resistance to weather aging. It has good melt strength for extrusion and thermoforming, and it can be easily coextruded. The recommended substrate is ABS (acrylonitrile-butadiene-styrene) resin.

Applications: Typical applications include those requiring weatherability and low gloss such as automotive and truck interiors, exterior siding and trim profiles. As with any product, use of Centrex 485 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

A. Schulman has acquired Network Polymers & Diamond Polymers.
