UHMW (Ultra High Molecular Weight Polyethylene)—sometimes referred to as UHMW plastic or UHMW polyethylene—is a highly durable, low-friction thermoplastic renowned for its outstanding wear resistance. At Northeast Plastics, we supply both UHMW sheets and UHMW rods, catering to industries that demand strong, machinable materials capable of withstanding demanding environments. If you’re comparing UHMW vs. HDPE, UHMW offers superior abrasion resistance and can be formulated for FDA compliance, making it an ideal choice for food processing, conveyor parts, and various industrial applications.

BEnefits of UHMW
Exceptional Wear Resistance
Outperforms many other polymers in abrasive environments, making it perfect for UHMW wear strips and conveyor components.
Low Friction Surface
Provides a smooth surface for high-speed contact, reducing drag and improving equipment efficiency.
High Impact Strength
Withstands heavy impacts without cracking, suitable for protective linings and industrial parts.
Chemical & Moisture Resistance
Maintains stability in the presence of many chemicals, while moisture absorption is extremely low—ideal for wet or corrosive settings.
Applications for UHMW

anything
What Is UHMW Used For?
UHMW is commonly used in high-wear applications such as conveyor systems, industrial chutes, and food processing equipment. Its low friction and exceptional abrasion resistance make it ideal for long-lasting parts.
Is UHMW FDA Approved?
Certain grades of UHMW are indeed FDA-approved, making them suitable for direct food contact. Be sure to confirm with your supplier that the specific material meets all relevant regulations for your application.
How to Machine UHMW Polyethylene?
Machinable UHMW plastic is best handled with sharp tools at moderate speeds. Keep the material cool to avoid melting, and secure it firmly to minimize vibration or warping. UHMW’s low friction properties also mean it’s less likely to stick or bind during machining.
How Does UHMW Compare to HDPE?
Both UHMW and HDPE are polyethylene-based plastics. UHMW vs. HDPE usually comes down to wear resistance: UHMW has a higher molecular weight and offers better abrasion and impact resistance, making it more durable in high-friction or heavy-impact environments.
