General purpose acrylic impact modifier that improves the impact properties, processing and surface finish of rigid vinyl compounds.

Developed on a high-rubber content design, Durastrength® 350 modifier offers faster fusion without the need for additional process aids, and superior impact performance at 3 to 4.5 phr, when compared to competitive high-rubber modifiers.

New generation composite acrylic core-shell material that imparts superior impact properties to outdoor vinyl applications. It provides higher impact strength and wider processing window than Durastrength® 365, leading to unmatched cost/performance balance on the market. Durastrength® 365S impact modifier is particularly valuable in mixed metal stabilized applications and where double-V notch Charpy impact and/or falling weight impact resistances are required.

A new generation of composite acrylic core-shell impact modifier that presents improved impact properties and corner weld strength versus current non acrylic solutions. It is used primarily in outdoor vinyl applications. Durastrength® 367 is recommended as an alternative to non-acrylic impact modifier in applications where improved impact properties are required.

New generation high-rubber acrylic impact modifier designed to meet the most demanding impact standards in durable vinyl applications.  Even at low use levels in challenging applications like vinyl window profiles, Durastrength® 382 acrylic impact modifier delivers high impact strength, a wide processing window, and high gloss surface finish.  The formulation has been optimized for use with Ca/Zn stabilizers and is also useful in C-PVC or flexible vinyl applications.

Provides expected impact performance while delivering benefits of acrylic fusion promotion. It imparts excellent properties to rigid PVC products and provides outstanding processability.  DURASTRENGTH® 4000 impact modifier can be used in place of alternative non-acrylic impact modifiers while maintaining the processing advantages of traditional impact modifiers.

Novel acrylic chemistry designed to impart excellent ambient and superior cold temperature impact to Polycarbonate and its alloys. Durastrength® 440 impact modifier also demonstrates excellent efficiency in thermosetting applications where UV resistance is needed.

Outperforms nearly any other acrylic or MBS modifier in polycarbonate high temperature aging color hold. This hot climate performance has been demonstrated in studies up to 120°C. Durastrength® 480 acrylic impact modifier is especially useful to mold-in color users in the automotive, lawn and garden, and recreational markets for its adaptability to all climate conditions. It also demonstrates excellent efficiency in thermosetting applications where UV resistance is needed.

Designed to offer cost savings to users, Durastrength® 506 impact modifier is based on Arkema’s proven acrylic core-shell technology. In injection molding applications, Durastrength® 506 acrylic impact modifier is especially useful and offers fast fusion and excellent impact performance without the need for additional process aids.

Designed to improve flow in compounds through extrusion, extending screw and barrel life while increasing productivity.  This results in improved aesthetic properties, weatherability, and impact strength even when used with high amounts of filler as is common in vinyl siding applications.

Designed for use in window profiles, capstock solutions and other weatherable vinyl applications, Durastrength® 527 enables a broad processing window and best-in-class impact strength based on efficiency.

Improvement on Durastrength® 510 modifier, offering faster fusion, and improved impact performance for the same use level (phr). These improvements do not compromise the superior surface gloss and finish offered to window profile, siding, fencing, pipe, and injection molded articles.

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.

Arkema's acrylic-based impact modifiers are designed to deliver optimum cost and performance in rigid and flexible PVC applications for siding, fence, deck, rail, pipe and injection molding applications.
