Problem

Food conveyor rollers used in food processing equipment need to withstand constant movement & must be easy to clean to reduce risk of contamination. Material used in the rollers needs to be approved for food contact & have excellent wear resistance.

Solution

RTP 800 Series acetal with PTFE & silicone.

Benefits

  • Improved wear resistance
  • Excellent lubricity
  • FDA compliant
  • Chemical resistance to cleaning solutions
Conveyor Rollers

Application: Disposable Pump

Problem

Traditional metal pumps used in the food, dairy, chemical, medical and pharmaceutical industries face contamination issues, which create down-time for maintenance and high cleaning costs. Multiple material requirements include: wear resistance, maintaining low warpage and low creep at operating temperatures of 110°C (230°F), and low moisture absorption to minimize swelling.

Solution

RTP 1300 Series polyphenylene sulfide glass fiber reinforced compound with PTFE.

Benefits

  • Excellent chemical resistance
  • No need for external lubricants
  • FDA compliant polymers and ingredients
Disposable Pump

Application: HVAC Gears

Problem

Due to extreme temperature changes (-40 0c to 80 0c) gears were creating excessive noise leading to warranty issues.

Solution

RTP 200 series and 800 series with glass fiber and PTFE.

Benefits

  • Noise reduction
  • Low friction
  • Improved wear resistance
HVAC Gears

Application: Micro Pump Gears

Problem

Chemically resistant materials need to pump a wide variety of fluids over a wide temperature range including: espresso, water, pesticides, carbonated drinks, & alcohol. Application requires high wear materials but cannot utilize glass fiber.

Solution

RTP 2200 Series Peek with carbon fiber, aramid fiber & PTFE.

Benefits

  • Excellent chemical & corrosion resistance
  • High strength
  • Wear resistant
  • High heat resistance – Many micro pumps operate at very high speeds creating high temperatures at the wear interface

Application: Wear Rings

Problem

Wear rings are used in hydraulic cylinders and pistons. They require a material with good wear resistance and low coefficient of friction, and must maintain tight tolerances and perform against petroleum oils, fluids and greases over a temperature range of -40°F to +275°F.

Solution

RTP 207A Series TFE13 Si2 HS black heat stabilized glass reinforced nylon 6 with PTFE and silicone.

Benefits

  • Resistant to petroleum oils, fluids and greases
  • Dimensionally stable
  • Combination of good wear resistance and low coefficient of friction
  • Performs over a broad temperature range
