An Overview of Ultra High Molecular Weight Polyethylene Tapes

Ultra high molecular weight (UHMW) polyethylene tapes are known for their durability, low friction, and chemical resistance. These properties make them ideal for a variety of industrial applications.

UHMW tapes are composed of long, linear polyethylene molecules that are closely packed together. This results in a tape with high tensile strength, impact resistance, and abrasion resistance compared to other plastic tapes.

Some key properties and benefits of UHMW tapes include:

• Extremely low coefficient of friction
• High tensile strength
• Excellent abrasion and wear resistance
• Resistant to chemicals and solvents
• Low moisture absorption
• Flexibility even at low temperatures

Common Applications

UHMW tapes are commonly used in:

• Chutes and hoppers
• Conveyors
• Dust and powder control
• Noise dampening
• Gearmotors
• Tank and vessel guides
• Roll covering

They provide protection, smooth flow, and noise reduction in manufacturing and industrial settings.

Applications of DeWAL UHMW Tapes

DeWAL’s tapes are designed to excel in the following applications:

Chutes, Hops, and Silos

The low friction and non-stick properties make them ideal for lining chutes to prevent material hang ups and promote smooth flow.

Conveyors

They provide good impact absorption and abrasion resistance for conveyor side guides and pulley lagging.

Tanks and Vessels

Excellent chemical resistance allows use as tank and vessel guides or protectors.

Noise Reduction

Effective at absorbing noise and vibration when used as sound dampening pads or tapes.

Gearmotors

Can protect drive motors and gears from wear and abrasion damage.

FAQ

What are some benefits of DeWAL UHMW tapes?
