Combining advanced materials for optimum performance

One of the great things about rubber is that it can be bonded to just about any other material.

A real benefit that we have seen in recent times, with the development of exceptional materials – carbon fibre, PTFE, acetal, acrylic, Peek® – is that rubber can be chemically bonded to them and therefore provide the best of both worlds.

Rubber to plastic bonding

A rubber seal with a PTFE lip; a carbon fibre substrate with a bonded rubber lip; a composite wear pad made of rubber and PTFE. Very often a seal needs to be in contact with a moving surface in order to perform its intended function – but in doing so can create too much friction. A combination of rubber and PTFE can form a compliant but low-friction seal. Alternatively, the PTFE can be used right at the tip of the seal to reduce the likelihood of damage through overheating – but will be energised by the main bulk of the seal which is still manufactured from rubber.

Rubber can be chemically bonded to most polymers, and this dual-material solution is now used across a range of applications, providing a solution that is greater than the sum of its parts and requires fewer stages in the final assembly of the product.
