For Engineers

There are many reason engineers choose rubber:

  • Rubber can withstand exposure to fuels, oils, and chemicals. Whilst retaining its excellent properties
  • 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 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 available in a wide range of colors
