A. Schulman Diamond Centrex® 835 Sheet Extrusion Grade  (discontinued **)
Categories: Polymer; Thermoplastic; ASA Polymer

Material Notes: Centrex 835 resin is a low-gloss grade of ASA (acrylonitrile-styrene-acrylate) with good resistance to weather aging. It has good melt strength for extrusion and thermoforming applications. Centrex 835 can be easily coextruded over ABS (acrylonitrile-butadiene-styrene) resin.

Applications: Typical applications for Centrex 835 resin includes those requiring weatherability and low gloss, such as truck and bus interiors and exteriors and tonneau covers. As with any product, use of Centrex 835 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.
