DOW™ DA61 HL Enhanced Polyolefin Resin

What is DOW™ DA61 HL Enhanced Polyolefin Resin?

A resin used in extruded acoustic barrier compounds for flooring, wheel well, and dash mat applications, providing enhanced acoustic comfort. Its unique polymer architecture allows for high levels of organic filler while maintaining mechanical properties. The non-polar polymer structure results in compounds with low volatile organic content (VOC) emissions, exceptional durability, and the ability to recycle industrial scrap.

Uses

Acoustic barrier application: Dash mat/firewall, flooring, wheel well, and door applications

Benefits

High filler level loading (~75wt% or greater) while maintaining excellent tensile and tear properties
Exhibits low crystallinity, providing flexibility with low oil content
Completely free of phthalates and vinyl acetate, resulting in low VOC and odor emissions
Offers excellent durability and ductility at temperatures as low as -30°C
Allows for the potential mechanical recycling of post-industrial scrap
Demonstrates excellent rheology for web stability during extrusion
Provides outstanding melt elongation, resisting thinning or tearing during thermoforming
Potential for enhanced automation due to the reduced number of components needed
