Kelseal Rubber Mouldings Group is a specialist commercial moulding manufacturer supplying to various industries throughout Australia. Unfortunately we do not do small non commercial runs of less than 1000 on washers, seals or rings.
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
- Viton® 75 & 90 Durometer
- Neoprene
- EPDM
- Silicone
- Fluorosilicone
- PTFE
- FEP Encapsulated Viton & Silicone
- Aflas®
- Kalrez® - perfluoroelastomer
