Acrylic-based Durastrength® acrylic impact modifiers are free flowing powders designed to deliver optimum cost and performance.

Acrylic-based Durastrength^® acrylic impact modifiers are free flowing powders designed to deliver optimum cost/performance in PVC profile, siding, fence, pipe and injection molding compounds. Durastrength^® products offer superb weatherability, improved processing with better flow, more even pigment dispersion and heat stability, as well as greater impact strength even at low temperatures. 

Durastrength^® 619 is an acrylic impact modifier that imparts excellent impact properties to rigid PVC products and provides outstanding processability without adding process aids for most applications. Durastrength^® 619 offers formulation flexibility through a combination of excellent impact resistance and processability. Superior impact performance can be used to improve properties or decrease modifier loading at constant performance.  It can be used as a high efficiencly modifier system for siding, window profile and pipe fitting and conduit.  It is also suitable for all outdoor/weatherable PVC applications.

Durastrength^® 510 is an acrylic modifier that imparts superior impact properties and processability to rigid vinyl products at lower acrylic use levels. Durastrength^® 510 offers outstanding room and low temperature impact in combination with unsurpassed ease of processing. The unique properties of Durastrength^® 510 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 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^® 506 is an acrylic modifier that imparts superior impact properties and processability to rigid vinyl products. Durastrength^® 506 offers outstanding room and low temperature impact in combination with unsurpassed ease of processing. The unique properties of Durastrength^® 506 make it especially suitable for injection molding applications. Additionally, the excellent processability, flawless surface finish and high gloss imparted by Durastrength^® 506 make it a natural for window and door profile applications where these properties are key.

Durastrength^® 400 series impact modifiers are based on novel, patented, all-acrylic chemistries that provide low temperature toughening beyond that of conventional acrylic impact modifiers in engineering resins (polycarbonate, polyesters, and polycarbonate blends). Durastrength^® 400 series impact modifiers should be used wherever weatherability (UV, thermal) is required such as in the automotive, lawn & garden, nd sporting equipment markets. All Durastrength^® 400 series modifiers are designed to provide exceptional impact strength, mold-in colorability, and surface appearance while minimizing their effect on other mechanical properties and processability.

Durastrength^® 320 is an 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^® 200 is an acrylic impact modifier that imparts superior impact properties to rigid vinyl products. The unique chemistry of Durastrength^® 200 has made it the leading impact modifier used in exterior durable building products for over 25 years. Durastrength^® 200 offers outstanding long term weather resistance, impact retention and low temperature impact in combination with unsurpassed ease of processing.
