Durastrength® 731

Durastrength® 731 is a low gloss impact modifier imparting excellent mechanical properties to rigid vinyl building products. While providing lower gloss values in co-extruded and monoextruded vinyl capstocks and profiles, Durastrength® 731 maintains impact properties necessary to meet standards across the building and construction market. Durastrength® 731 meets the weatherability of all Durastrength® impact modifier grades and provides the processability and rheology needed by vinyl rigid PVC manufacturers.
