Durastrength® 506

Durastrength® acrylic impact modifiers

Durastrength® 506 acrylic impact modifier was the first development in Arkema’s line of multifunctional acrylic modifiers.  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.  Molded vinyl fittings makers achieve fast fusion and excellent impact performance without the need for additional process aids.  This provides a savings in the total acrylic content of these vinyl formulations.
