WebbSilicones are polymers with a Si-O-Si backbone. There are different types depending on functional groups in the structure and curing mechanisms. Key properties include thermal stability, chemical stability, electrical insulation and low toxicity. Main applications are flexible seals, o-rings etc. WebbNitrile butadiene rubber (NBR) is a family of unsaturated copolymers. It is resistant to oil, fuel and other chemicals (the more nitrile within the polymer, the higher the resistance to …

Webbexpansion pressures that fit well with liquid-like theoretical predictions under both thermal and solvent exposures. Harder silicone elastomers fit well with elastomer-like predictions for thermal expansion, but were in-between liquid and elastomer predictions with solvent swell. References 1.
