No, you can’t coat UHMW on because of two reasons: It does not melt to form a continuous surface.; It requires pressure to weld all the unmelted particles at high temperatures. Is there an alternative to coating parts? UHMW can be manufactured in conductive or anti-static forms making it ideal for use in electronics and semi conductor applications. Is UHMW UV stable?
Not for most applications. The reason is the large d ifference between the coefficient of thermal expansion of metal and UHMW puts high stresses on the bond if the bond encounters temperature extremes. What are my installation options for UHMW? Yes, UHMW-PE is both FDA and USDA approved for use in food processing and medical applications. How do you differentiate UHMW from HDPE? Hydrogen and nitrogen don't affect it, but oxygen could. Are there any high performance blends that can be added to UHMW-PE? Due to its abrasion-, corrosion-, chemical- and moisture-resistant properties, TIVAR® is commonly used in applications where conditions may be too harsh for other materials. It is a cost-effective high performance polymer used to produce low cost, high quality parts. How does TIVAR® compare to other materials?

Friction properties: Both UHMW tape and PTFE tape have excellent low-friction properties, but PTFE has an exceptionally low coefficient of friction. PTFE is often referred to as “the most slippery substance” due to its extremely low friction, which makes it ideal for applications where reduced friction is crucial. Yes, UHMW does not absorb water and is chemically inert. How does UHMW protect metal from wearing away? Although TIVAR® never actually melts, it will begin to lose its excellent properties at a temperature of 180 degrees F (82 degrees C). TIVAR® will generally perform very well down to cryogenic temperatures, but like other plastics, it will expand and contract with variations in temperatures. Is UHMW available in a conductive or anti-static form? UHMW-PE stands for Ultra High Molecular Weight Polyethylene. It is the highest quality polyethylene (PE) available, engineered for tough jobs and a wide range of applications. It delivers savings in a number of difficult applications. Ultra High Molecular Weight is the secret of this polymer’s unique properties. Its high-density polyethylene resin has a molecular weight range of 3 to 6 million, compared to 300,000 to 500,000 for high molecular weight (HMW) resins. That difference is what ensures that this material is strong enough to withstand abrasion and impact better than lower level poly products. UHMW-PE’s high molecular weight means it will not melt or flow as a molten liquid. Processing methods are therefore derived from those of powder metal technology. UHMW-PE cannot be transformed and molded by conventional plastic processing techniques (injection molding, blow molding or thermoforming). Compression molding is the most common conversion process used with this resin because it produces a stronger, more consistent product. What is TIVAR®? TIVAR® is the brand name (from Poly-Hi) for a special formulation of ultra high molecular weight polyethylene (UHMW-PE). UHMW-PE is a unique family of high-density polyethylene with a molecular weight 3 million or higher. UHMW-PE is a high performance polymer with a high melt viscosity that can be extruded, fabricated or compression molded. What does TIVAR® stand for?
UHMW has no UL recognition. It would be HB on UL-1 – that is slow burning (less than 3″ per minute). How can you tell if a sample of UHMW contains regrind? UHMW Film Tape 5423 is often used in general industrial applications to help control squeaks and rattles due to vibration or wear of metal and plastic materials. Our UHMW-PE (ultra-high molecular weight polyethylene) film tape provides good chemical resistance and excellent abrasion resistance that helps ensure a long wear life. Wear and abrasion resistance– UHMW tape is utilized in applications where high levels of wear and abrasion resistance are required. It can be applied to components subjected to sliding, rubbing, or impact, such as wear strips, skid plates, guide rails, or cutting surfaces. The use of UHMW tape spans across multiple industries, each leveraging its unique properties for various purposes: Low Coefficient of Friction: This feature minimizes wear on surfaces, extending the lifespan of machinery and equipment.

UHMW (Ultra-High Molecular Weight Polyethylene) tape and PTFE (Polytetrafluoroethylene) tape are both used for various applications due to their low-friction, high slip properties. However, there are some key differences between the two: Saw Test – When cut with a saw, regular HDPE gives sawdust or filings while UHMW gives strings or nothing.
UHMW PE Film Tape 5421 is often used in general industrial applications to help control squeaks and rattles due to vibration or wear of metal and plastic materials. Our UHMW-PE (ultra-high molecular weight polyethylene) film tape provides good chemical resistance and excellent abrasion resistance that helps ensure a long wear life. Automotive Sector: In automotive applications, this tape is used for noise reduction, protecting surfaces from abrasion, and providing a smooth, low-friction surface for moving parts. Medical Field: Its biocompatible nature finds use in medical equipment to reduce friction and protect sensitive components, ensuring smooth operation and longevity.Chemical Resistance: UHMW tape remains stable and reliable, even in the presence of various chemicals, ensuring its efficacy in challenging environments. Sliding and friction reduction – UHMW tape has excellent low-friction properties, making it ideal for applications that require smooth sliding or reduced friction. It can be applied to drawers, sliding surfaces, conveyor belts, chutes, and other components to facilitate easy movement. Water solutions are generally safe except highly oxidizing chemicals such as bleach. Hydrocarbons such as gasoline, kerosene, oil and grease cause swelling. Chlorinated solvents cause swelling. Organic alcohols, ketones and acids have little effect. How does the environment affect UHMW?
For applications where the primary purpose is to protect surfaces from scratches, abrasion, or wear, thinner UHMW tapes are commonly used. These thinner tapes provide a low-friction surface and can be applied to various surfaces, including metals, plastics, and painted surfaces.TIVAR® is known for its high abrasion resistance, natural lubrication, high impact strength, chemical-, corrosion-, and moisture-resistance and acoustic impedance. Why use TIVAR®?
