Our In-house Laboratory

We have a well-equipped laboratory that can test the physical properties of rubber and control product quality. All testing equipment undergoes annual calibration every year to ensure the accuracy of the test data.

Designers 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.
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 grades available.
Rubber can maintain tension and compression forces for sealing applications.
Rubber is conformable, adaptable and can accommodate movement, shock, and thermal changes, operating with tight tolerances and in a variety of surface finishes.
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 colours.
