Durastrength® 535

Durastrength® acrylic impact modifiers

Durastrength® 535 acrylic impact modifier (D535) is an improvement on Durastrength® 510 modifier (D510), offering faster fusion, and improved impact performance for the same use level (phr). The faster flow of compound through single and twin-screw extruders found in D510 is improved with D535, even without the use of additional process aids.  These improvements do not compromise the superior surface gloss and finish offered to window profile, siding, fencing, pipe, and injection molded articles.
