April 2010 | Focus: UHMW-PE
Addressing questions and statements about UHMW-PE
Many articles have been written about the characteristics of UHMW-PE (ultra high molecular weight polyethylene) that make it so popular. For high-wear applications, UHMW-PE is the answer to many impact, release and abrasion problems. The unique combinations of properties of UHMW-PE continues to be the driving force in its market growth, However, these are some myths and misconceptions that we would like to address and some new formulations and profiles that offer interesting opportunities.

Uses of UHMW-PE: From the fields to the grain elevator
The agricultural industry faces a myriad of challenges through the range of its processes: from soil preparation, seed planting and crop harvesting to the delivery of farm products to market. Farmers face the prospects of rising energy costs, poor crop conditions, climate change and low crop prices. The very harsh physical environment farming equipment is exposed to is just as demanding. The effects of moisture, abrasion and impact are deleterious to the effectiveness and durability of farm equipment and components. UHMW-PE offers reliable solutions to the farmer by extending equipment life and improving operational efficiency. Read more.

Going “extreme” ultra high — a very versatile engineering plastic
UHMW-PE has been proving for more than 50 years that it can “go extreme” in many very demanding applications and environments. Whether in cryogenic applications as low as -445°F (-265°C), under extremely abrasive environments like in linings for bulk material handling or dewatering elements in the paper industry, as guides for chains and belts in high speed conveying applications, as shielding elements in nuclear applications, as medical grade in orthopedic implants, in food or pharmaceutical applications, as large parts made from 33 feet long and almost 8 inches thick compression-molded monobloc, or as extremely small and intricate parts used in seals, UHMW-PE provides uncountable possibilities to provide a solution.
