Polyethylene (LDPE, HDPE, UHMW)

HDPE and LDPE Massive HDPE Round Rod 19

High Density Polyethylene (HDPE) and Low Density  Polyethylene (LDPE) are both materials 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®, UltraEthylux®, Polycarve®, and Densetec®.

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

Why use HDPE/LDPE for your application?

  • 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
