Polyethylene

HDPE & LDPE

(High Density and Low Density Polyethylene)

Plastic Rod from .250

Both materials are in the Polyolefin family of plastics, along with Polypropylene (PolyPro) and UHMW (Ultra High Molecular Weight). Manufactured by a variety of manufacturers under the names: Polyboard, Polymar, Hostalen, Polystone, Hitec, Sanatec, Sanalite, Ultra Ethylux, Polycarve, and Densetec.

For great abrasion resistance, very low density and FDA/NSF compliance, Polyethylene is an excellent choice.

Occasionally we are asked for the difference between Acetal and HDPE – here is an explanation.

Still not sure HDPE/LDPE Polyetheylene is the proper material for your application, consult our free Plastic Materials Selection Guide.

Why use HDPE/LDPE in your applications:

  • Light Weight
  • Stain, Odor and Moisture Resistant
  • FDA & NSF Approval for Food Contact
  • Vacuum and Thermo-Formable Material
  • Very Durable and Abrasion Resistant

This materials is…exhibit high impact strength, abrasion resistance and low coefficient of friction. Very light weight (density of .91 – .96) and extremely durable. FDA and NSF approved for food contact. Low forming temperature for ease of vacuum or thermo-forming.

  • Self Lubricating and Low Co-Efficient of Friction
  • Very High Chemical Resistance
  • Low Specific Gravity (Floats in Water)
  • Can be Heat Welded or RF Welded
  • High Impact Strength and Energy Absorption
  • Excellent Wear Resistance and FDA/NSF Approved
  • Exceptional Low Temperature – Brittle at -110 degrees F
