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. Dedicated information on regulatory status is available upon request.
