Specialist Elastomers
Therban
(HNBR)
Hydrogenated nitrile rubber provides good all round performance at a compound cost between Nitrile and Fluoroelastomer. Its highly saturated main chain provides good resistance against thermal oxidation and chemical attack.
Properties
- good physical properties, including abrasion resistance, at high temperatures
- good dynamic behaviour and flex cracking resistance at elevated temperatures
- excellent heat, ageing and ozone resistance
- outstanding resistance to steam and hot water
Limitations
- no inherent flame retardency
- poor electrical properties
- unsuitable in contacts with aromatic and polar organic solvents
Typical Applications
- diaphragms requiring chemical and heat resistance
- chain tensioners and seals in vehicle engines
- oil exploration and production
Epichlorohydrin
A synthetic rubber designed for more extreme heat and oil resistance applications. Best described as a “super” Nitrile.
Properties
- very good high temperature resistance, up to 150°C
- good low temperature properties
- good ozone resistance
Limitations
- expensive
- may require higher cost tooling
- relatively low physical strength
Typical Applications
- automotive applications such as fuel systems
- printing rollers
