Reinforced High Density Polyethylene Compounds
Spartech Polycom's filled high molecular weight, high density polyethylenes are specifically designed for blow molding and sheet extrusion /thermoforming of structural parts. These materials offer an excellent balance of stiffness, impact resistance and dimensional stability. Typical applications for blow molding grades include automotive seat cores, heating ducts, and recreational products such as ice chests. The talc filled materials are color matchable for appearance applications.
The following chart highlights some of our more common HDPE compounds.
