Durastrength® 4000

Durastrength® 4000 by Arkema is a multifunctional, acrylic-based impact modifier. It imparts excellent impact properties to rigid PVC products and offers outstanding processability. It offers faster fusion than alternative non-acrylic impact modifiers without the need for additional processing aids.

• It exhibits great impact resistance, and low melt viscosity.
• It provides good stability, smooth processing and high output rates in vinyl formulations.
• It offers sustainable performance with a reduced carbon footprint of up to 35% compared to traditional acrylic additives.
• It uses patented technology to reduce the ratio of fossil materials and lowers energy consumption in production processes.
• It can be used in place of CPE impact modifiers while maintaining the processing advantages of traditional acrylic impact modifiers.
• Substrate applications utilizing Durastrength® 4000 maintain important mechanical properties for final PVC product performance.
• It is recommended for rigid siding, ribbed pipe, fence and deck substrate.
