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.
