Product Spotlight: TIVAR® Ultra-high Molecular Weight Polyethylene

Did you know? Mitsubishi Chemical Group Engineered Shapes & Solutions (ES&S) is the world’s largest supplier of ultra-high molecular weight (UHMW) polyethylene shapes and parts.

With processing facilities in the U.S., Germany, Japan, and South Africa, we deliver high-performance solutions wherever you need them.

Why UHMW Polyethylene?

First commercialized in 1950s Germany, UHMW polyethylene is now processed into powders for molding by a select group of global resin companies, including Ticona/Celanese, Braskem, Mitsui, and Teijin. A slightly larger group of processors then shapes these resins into durable parts, often serving niche markets.

The Legacy of TIVAR®

Our expertise in UHMW polyethylene comes from acquiring two industry pioneers—PolyHi and Solidur—who set the standard for wear- and abrasion-resistant materials. These innovators developed processes that preserve high molecular weight, ensuring outstanding durability and performance. The result? TIVAR®—a trusted choice across industries.

The TIVAR® Advantage

TIVAR® outperforms high molecular weight (HMW) polyethylene and high-density polyethylene (HDPE). It even bests pipe-grade polyethylene, which is sometimes presented as comparable to UHMW polyethylene, but lacks the same performance. Molecular weight in the material determines its performance, and TIVAR® is engineered for the toughest applications.

TIVAR® shapes have replaced nylon, wood, bronze, and ceramic parts in demanding environments, offering:

  • Lower friction—reduces or eliminates external lubrication
  • Improved material flow—prevents sticking in bulk materials like packaging
  • Quieter operation—reduces noise in mechanical systems
  • Longer part life—excels in wet, abrasive environments
