ultra-high-molecular-weight polyethylene (UHMWPE)

UHMWPE stands for Ultra-High-Molecular-Weight Polyethylene. It is a type of thermoplastic polyethylene characterized by its extremely long chains of polyethylene, which result in a very high molecular weight, typically between 3.5 to 7.5 million atomic mass units (amu).

Several companies manufacture UHMWPE under various brand names. Here are some of the most well-known brands:

1. Dyneema®: Produced by DSM, Dyneema is one of the most recognized UHMWPE fibers. It is known for its high strength-to-weight ratio and is used in a variety of applications, including personal protective equipment, ropes, and medical devices.

2. Spectra®: Manufactured by Honeywell, Spectra is another prominent UHMWPE brand. It is used in applications such as body armor, fishing lines, and high-performance sails.

3. Tivar®: This brand, produced by Quadrant (now part of Mitsubishi Chemical Advanced Materials), focuses on industrial applications, providing UHMWPE sheets, rods, and profiles for use in conveyor systems, chutes, and liners.

These brands represent some of the leading producers of UHMWPE, each offering products tailored to specific industries and applications.

Last but not least, China Brand of UHMWPE, we are supplying competitive prices and good quality.

Features & Benefits

  • High Impact Strength: UHMWPE has excellent impact resistance, making it highly durable and suitable for use in applications that require robustness.
  • Abrasion Resistance: It is highly resistant to wear and abrasion, which contributes to its longevity in demanding environments.
  • Low Coefficient of Friction: UHMWPE has a very low coefficient of friction, making it an ideal material for applications that require smooth and efficient movement.
  • Chemical Resistance: It is resistant to a wide range of chemicals, including many acids, alkalis, and organic solvents, making it suitable for use in harsh chemical environments.
  • Self-Lubricating: The material’s inherent slipperiness reduces the need for additional lubrication.
  • Biocompatibility: UHMWPE is biocompatible, meaning it can be used in medical applications, such as joint replacements.
  • Anti-Cut, Acid&Alkali- resistance, puncture resistance.
