Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, ... Compounding techniques allow for HNBR to be used over a broad temperature range, −40 °C to ...
The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of commercial applications, such as laptop sleeves, orthopaedic braces (wrist, knee, etc.), electrical insulation , medical gloves , liquid and sheet-applied ...
It is better for lower pressures than nitrile rubber and chemically much more inert. It is bakeable to 200 °C. It is bakeable to 200 °C. FFKMs ( FFPMs ) very low out-gassing similar to PTFE and withstands baking temperatures up to 300 °C, while chemically one of the most inert sealing elastomers.
PIB homopolymers of high molecular weight (100,000–400,000 or more) are polyolefin elastomers: tough extensible rubber-like materials over a wide temperature range; with low density (0.913–0.920), low permeability and excellent electrical properties.
