I have a cnc machine which uses a very hard but flexible plastic on the clamps.It is required to grip the components tight but does not compress under the clamping process (pneumatic clamping). I would like to be able to replace this as it is a square section about 10mm sq 70Mmm long and fits in a slot on the clamps.It would be easy to buy them from the machine manufacturer but at £7.00 each i think is a bit much.
Can you help in steering me towards the material i should be trying to source
