UHMWPE

OMEGA-ULTRA ®  UHMWPE Sheet and Rod

The OMEGA- ULTRA ®  Ultra-high molecular weight Polyethylene (UHMWPE) has a high abrasion resistance (very good glide characteristics) and a high toughness at the same time. The chemical and the crack resistance is optimised in comparison to the standard high density Polyethylene, and is therefore suitable for applications subject to continuous shocks. The operating temperature of UHMWPE is from -150°C to +90°C.

The OMEGA- ULTRA ®  UHMWPE is defined as polyethylene whose molecular weight is 3,100,000 or higher. It was found that physical properties increased rapidly as lower molecular weight values increased and then levelled off at this value. Because of its high melt viscosity, conventional moulding and extrusion processes would break the long molecular chains that give its excellent properties. These plastics have outperformed other materials including metals, in many applications.

 

MAIN ADVANTAGES of OMEGA-ULTRA ® UHMWPE Sheet and Rod

  • Low density and easy machinability
