Quadrant Engineering Plastic Products has introduced Tivar polyethylene (PE) bearing grade Tivar HPV for wear components that are subject to challenging production environments including high speeds, high temperatures, high loads and aggressive cleaning agents.

Tivar HPV is an ultra-high-molecular-weight polyethylene (UHMW-PE) that is Food-Contact compliant and available as semi-finished material and custom-machined parts.

The material is suitable for all touch points in a conveyor system where friction and wear appears, such as chain guides, sliding strips and guides, rollers, single and multiple corner wear bends and straight guides.

Key benefits

  • Components made with Tivar HPV offer improved sliding behaviour and high wear and abrasion resistance.
  • Tivar HPV has a built-in dry lubricant, giving it a limiting pressure velocity (LPV) value 18 per cent higher than competitive material, according to Quadrant.
  • The company said that POM-C counterplate tests it performed showed that Tivar HPV offers the lowest coefficient-of-friction value available.

Quadrant Engineering Plastic Products

Quadrant Engineering Plastic Products (QEPP) is the world’s leading manufacturer of semi-finished products made from general engineering and high-performance plastics. Quadrant also designs, develops and produces finished parts and solutions for a broad variety of applications in many different industries globally. Its product range extends from polyamide (PA), polyacetal (POM) and ultra high molecular weight polyethylene (UHMW-PE) to high-performance materials such as fluoroplastics and polybenzimidazole (PBI), which features temperature resistance to over 425C (800F) while maintaining total dimensional stability. The semi-finished products are machined or thermoformed and used in a variety of industries ranging from electronics through packaging machinery to chemical processing for applications where properties such as non-stick characteristics, abrasion resistance, dimensional stability, chemical and acid resistance or purity are extremely important.

Quadrant’s global teams of product development and applications engineers provide their customers with comprehensive advisory services. The best individual solution is sought for every customer requirement – from the choice of suitable material to optimum design of the finished product and machining of the most sophisticated materialsin state-of-the-art Technology Centres. Quadrant maintains a marketing and sales organization which is capable of pursuing new developments rapidly and efficiently worldwide. Quadrant focuses on growing markets, though many end users operate worldwide and have global requirements for materials and applications consulting.
