Durastrength® 731

Durastrength® 731 by Arkema is a low gloss acrylic impact modifier. It imparts excellent mechanical properties to rigid vinyl building products and lower gloss values in co-extruded and monoextruded vinyl capstocks and profiles. It offers weatherability, processability and rheology.

• It is recommended for use in tin and mixed-metal stabilized rigid vinyl formulations where reduced surface gloss is preferred for the final weatherable application.
• Durastrength® 731 is suitable for vinyl siding capstock, low gloss rigid profile including window, fence, deck, rail and rigid PVC applications using premium acrylic high-rubber technology and profile extrusions.
