UHMWPE Sheet

Ultra High Molecular Weight Polyethylene (UHMWPE) is thermoplastic engineering material, and its molecular weight can reach 4.5 to 9 million. It combines many characteristics such as abrasion-resistance, impact resistance/absorption, chemical corrosion resistance, low temperature resistance and self-lubrication etc.

Classification
  • General Type: Molecular weight is 4.5 to 9 million, in accordance with FDA and GB9687 standard.

  • Reinforced Type: Modified from general type, it has better temperature resistance and high strength.

  • Anti-static Type: Black color, anti static.

Features

  1. Low coefficient of friction, high abrasion resistance.
  2. Excellent chemical stability, corrosion resistance.
  3. Odorless, tasteless, and nontoxic.
  4. High impact resistance.
  5. Good self-lubrication, does not absorb conveying materials.
  6. Works well in wide temperature range (-150℃-85℃).
  7. Low water absorption, no dimensional change in wet condition.
