Engineers choose rubber because it has a wide range of properties.

  • Rubber is performs at a temperature range of  -80°c to +300°c .  Thus, it can withstand extremes temperatures of weather and outdoor environments indefinitely.
  • Rubber can withstand exposure to fuels, oils, and chemicals. Whilst retaining its excellent properties
  • Rubber is made flame retardant and with self extinguishing compounds with the suppressant chemicals found within the material.  Most are halogen free.
  • Rubber can maintain tension and compression forces is a very good way.  Such as seals and like applications.
  • 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 has reduced heat transfers in various applications.
  • 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 such as metals and plastics.  Is can be sonic welded or over molded together.  They can all be combined in many different ways.
  • Rubber is available in a wide range of colors
