UHMWPE ECO

Overview

Kormax UHMWPE Eco [short for Ultra-high Molecular Weight Polyethylene] has excellent chemical resistance, good fatigue, and excellent wear resistance. This material uses a portion of regrind from the premium grade in the production phase and thus minimizes what ends up in landfill. The specific gravity of polyethylene is less than 1; hence it floats in water and is easy to identify. Kormax UHMWPE Eco has great impact resistance, and can be used in temperatures as low as -80 °C. Most grades are non-toxic, however, UHMWPE Eco is not recommended for applications in direct contact with food but rather used for conveyors and other food processing machinery. Additionally, it is easily machinable.

Related Products

HDPE

Kormax HDPE [technical name High Density Polyethylene] has excellent chemical resistance, low moisture absorption and good impact resistance. Kormax HDPE is able to be welded, heat formed and machined using metal and wood working equipment. It is priced lower compared to other plastic materials. Being a polyethylene material, it floats in water, can be used in cold temperatures and food processing equipment/materials handling applications.

UHMWPE

Kormax UHMWPE [short for Ultra High Molecular Weight Polyethylene] has excellent chemical resistance, good fatigue and wear resistance. Specific gravity of polyethylene is less than 1, hence it floats in water and is easy to identify. Kormax UHMWPE has excellent impact resistance and can be used in low temperatures down to -80°C. Most grades are non-toxic and can be used in direct contact with food, and can be easily machined.
