TIVAR® H.O.T.

TIVAR H.O.T. [Higher Operating Temperature] is formulated to maintain inherent PE-UHMW key properties over an extended service temperature range, in this way considerably increasing part life in low load bearing applications up to temperatures as high as 125°C. Special additives reduce the oxidation rate of the material at higher temperatures thereby slowing down material degradation and extending wear-life. TIVAR H.O.T. also features a food contact compliant composition.

Product Description:

  • Inhibits oxidation, extends material wear-life

  • Extended operating temperature range

  • Abrasion-, corrosion-, chemical- and moisture-resistant

  • Excellent release characteristics

  • Meets FDA guidelines, USDA and 3-A Dairy compliant

Formulated to maintain key performance properties in an extended temperature range, TIVAR® H.O.T. will excel in a variety of industrial manufacturing environments where temperatures range up to 275° F, nearly 100 higher than competing UHMW-PE formulations. TIVAR® H.O.T. reduces the oxidization rate of the material at higher temperatures thereby slowing material degradation and extending wear-life in chemical, elevated temperature and thermo-cycling environments. In many applications, TIVAR® H.O.T. will last up to 10 times longer in higher temperature environments and has excellent wear and release characteristics

TIVAR® H.O.T. is also a great material for use in conveyor systems or other equipment that is frequently exposed to chemical washdowns in such industries as poultry/meat processing and packaging. It can be also be used in applications ranging from wearstrips for spiral conveyors in the baking industry to drag conveyor flights for moving bulk materials in grain elevators, or wearstrips for conveyor dryers in drying and dehydrating systems.

Applications:

  • Chain guides

  • Conveyor components

  • Drying equipment

  • Machined parts

  • Wearstrips, pads and plates

Industries:

  • Baking

  • Conveyor manufacturing

  • Food processing & packaging

  • Meat & poultry processing

  • Pet food manufacturing

  • Continuous use temperature up to 80 °C (176 °F)

  • Excellent release properties

  • Good performance in cryogenic environment

  • Good machining qualities allow production of more complicated parts

Applications:

  • Chain guider elements

  • Funnels

  • Rolls

  • Bushings

Improved Wear Resistance

TIVAR® DrySlide

Thanks to the lubricant built into a PE-UHMW matrix with higher molecular weight, TIVAR DrySlide offers a lower coefficient of friction and enhanced wear and abrasion resistance than TIVAR 1000. The additives used also make this material static dissipative and considerably improve UV-resistance.

Product Description:

  • Electro Static Dissipative

  • Ideal for dusty environments

  • Helps reduce surging

  • Won't mar packaging or products

  • Corrosion-resistant

  • Self-lubricating

  • Reduces noise

  • No moisture absorption

The enhanced coefficient of friction and anti-static properties make TIVAR DrySlide an excellent performer in dusty environments. Even damp boxes or parcels covered in shrink-wrap won't stick to TIVAR DrySlide. In addition, the enhanced surface lubricity won't mar packaging or products, but allow them to move freely without jamming from dirt, grit or static build-up.

TIVAR® TECH

This PE-UHMW grade with an extremely high degree of polymerization contains molybdenum disulphide, resulting in a material with improved wear resistance and sliding properties over TIVAR 1000.
