Rubber Products

Engineers choose rubber because of its wide range of properties:

  • Rubber can be used over a temperature range of  -80°c to +300°c . So it can withstand extremes of weather and outdoor environments indefinitely
  • Rubber can withstand exposure to fuels, oils, and chemicals. Whilst retaining its excellent properties
  • Rubber can be made flame retardant and self extinguishing, with halogen free and smoke suppressant types available
  • Rubber can maintain tension and compression forces indefinitely, e.g. seals
  • Rubber is conformable, adaptable and can accommodate movement, shock, thermal changes tolerances and roughness.
  • Rubber can absorb vibration and noise and act as an insulator
  • Rubber can be gas tight and used as a fluid seal or separator
  • Rubber has low thermal conductivity and can be used to reduce heat transfer
  • Rubber has friction properties similar to human skin and is comfortable to grip
  • Rubber can have a clean, smooth surface which can be non-stick and suitable for hygienic applications
  • Rubber is compatible with other engineering materials e.g. metal, plastics and ceramics and can be combined with them in many different ways, including bonding
  • Rubber is available in a wide range of colors
