Nitrile (Buna-N) NBR Material Guide | Eastern Seals

Nitrile (Buna-N) Nitrile rubber (NBR) is the general term for Acrylonitrile Butadiene Copolymer. It is the most widely used and economical elastomer. NBR offers excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols. It provides a good balance of desirable working properties including low

Compatibility of Elastomers in Neat Methanol Service

HNBR elastomers are a saturated version of NBR with superior heat resistance. These materials have excellent wear resistance, high tensile strength, high hot-tear resistance, low compression set, and good ozone and weathering resistance. Appliions are in oil-fields, and automotive. HNBR experiences some effects from methanol exposure

Gasket & Gasket Material Operating Temperature - RAM

Low Temperatures – When rubber is exposed to low temperatures the material changes from rubber-like entropy-elastic to stiff energy-elastic behaviour. This means that the rubber gets very brittle and can crack at low temperatures. Rubbers are generally used above a rigid glass state but the minimum temperature limit is not defined precisely.

3 Common Kegerator Problems & How to Fix Them - …

14/2/2019· Simply adjust the temperature in your kegerator to proper serving temperatures of between 8 and 13℃.
