Polyolefins  (LDPE, HDPE, UHMW, PP)

Polyolefin materials include Polyethylene and Polypropylene.  Both types of material exhibit excellent chemical resistance, toughness, and are lightweight.  Most formulations can be readily welded, machined, or formed.  Polypropylene has better strength and stiffness, while Polyethylene has better wear and abrasion resistance.  Polyethylene also has a very low coefficient of friction.

Polyolefins can be produced by utilizing Injection Molding, Extrusion, or Compression Molding (UHMW) methods.  The materials can also be compounded with numerous fillers to enhance their physical properties.

Low-Density Polyethylene – Flexibility, toughness, formability                                   

High-Density Polyethylene-  Increased strength, rigidity, abrasion resistance

Polypropylene – Homopolymer good strength, stiffness, weldable

Polypropylene – Copolymer, good strength, stiffness, weldable

UHMW  – Ultra High Molecular Weight Polyethylene, good wear, abrasion, and impact
