O-Ring Elastomers


The base polymer of an elastomeric compound is called rubber. That may be a natural rubber or, more commonly today, a synthetic rubber.

An elastomeric compound typically contains 50-60% of a base polymer with the remainder consisting of various fillers, vulcanising agents, accelerators, ageing retardants and other chemicals that modify the physical properties of the base polymer to suit specific applications.

O-rings are available in the following compounds:

Nitrile 70 & 90 Durometer Fluorosilicone
Viton® 75 & 90 Durometer PTFE
Neoprene FEP Encapsulated Viton & Silicone
EPDM Aflas®
Silicone Kalrez® - perfluoroelastomer
