Durastrength®

Durastrength® 200 NA is a general purpose acrylic impact modifier that improves the impact properties of rigid vinyl products. The unique chemistry of Durastrength® 200 impact modifier has made it the leading impact modifier used in exterior durable building products for over 35 years. Durastrength® 200 impact modifier offers outstanding long- term weather resistance, impact retention and low-temperature impact resistance in combination with unsurpassed ease of processing.

Durastrength® 320 NA is an acrylic impact modifier that imparts excellent impact properties to rigid vinyl products. It was designed to give the impact resistance necessary to pass critical impact test procedures, while maintaining excellent weatherability, processability and flow properties of Durastrength® 200 impact modifier.

Durastrength® 350 impact modifier is a high performance acrylic impact modifier that imparts superior impact properties to rigid vinyl products. It was designed to give the impact resistance necessary to pass critical impact test procedures, while maintaining the excellent weatherability, processability and flow properties of Durastrength® 200 impact modifier.

Durastrength® 4000 acrylic impact modifier represents the newest, low cost technology that imparts excellent impact 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 acrylic impact modifiers.

Durastrength® 440 impact modifier is based on novel acrylic chemistry designed to impart excellent ambient and cold temperature impact to PC and PC blends.

Durastrength® 480 is an acrylic core shell modifier designed to impart excellent impact properties and cold temperature toughness to engineering polymers, such as polycarbonate and its blends. Durastrength® 480 impact modifier offers outstanding long-term weather resistance and is ideal for outdoor applications.

Durastrength® 510 acrylic impact modifier imparts excellent impact properties and faster fusion to rigid vinyl products at lower acrylic use levels. Based on the unique chemistry of Durastrength® 200 impact modifier which has been the leading impact modifier used in exterior durable building products for over 35 years, Durastrength® 510 impact modifier offers outstanding room and low-temperature impact in combination with unsurpassed ease of processing. The unique properties of Durastrength® 510 impact modifier make it especially suitable for vinyl siding and fence substrate formulations where high filler levels and high production rates put maximum stress on the formulation. Due to its unique process aid functionality, Durastrength® 510 impact modifier eliminates the need for added process aid in formulations that it is used to modify. This efficiency typically enables a reduction in total acrylic level needed in most formulations.

Durastrength® 527 is a high performance, highly efficient impact modifier 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.

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.

Durastrength® 600 is an acrylic core shell impact modifier designed to impart excellent toughening properties to polyester and alloys containing polyester resins, such as PET, recycled PET (rPET) and engineering resin blends containing polyesters like PC/PET, PC/ABS/PET and PBT/PET. Durastrength® 600 impact modifier offers outstanding long-term weather resistance and is ideal for outdoor applications.
