Elastomers are dimensionally stable, but elastically deformable plastics whose glass transition point is below room temperature. The plastics can deform under tensile and compressive load, but then return to their original, undeformed shape. Elastomers are used as material for tires, rubber bands, sealing rings, etc.
By applying a mixture of PTFE and bonding resins, the surface is provided with an elastic layer having a thickness of about 25 to 35 μm. The compound is firmly adherent to the elastomer and remains elastic. The friction coefficient is significantly improved.
The advantages of this method are:
- permanently low coefficient of friction
- lasting good dry running properties
- no stick-slip effect
- improved aging resistance
- can be used in dynamic applications
- can be applied to parts of the rubber seal
