Nitrile rubber - Wikipedia

Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. Trade names include Perbunan, Nipol, Krynac and Europrene.This rubber is unusual in being resistant to oil, fuel, and other chemicals. NBR is used in the automotive and aeronautical industry to make fuel and oil handling

Developments in fuel hoses to meet changing environmental

1/3/1994· In the late 1970s, ECO also came into use in fuel hose tubes due to its low fuel permeability and heat resistance. NBR had often been described as a ''100 degrees C rubber,'' but it could, in fact, meet fuel hose tube specifiions calling for resistance to cracking on being straightened after being bent for 720 hours at 125 degrees C (ref. 6).

What is SBR | ELBEX

What is SBR? SBR, also known as BunaS, is a synthetic copolymer of styrene and butadiene. SBR was originally developed to replace natural rubber in tires and its use in the manufacture of tires continues to the present day. SBR and natural rubber account for 90% of the total world rubber consumption. SBR has a typical service temperature range

nitrile rubber | synthetic rubber | Britannica

NBR is made in a hydrogenated version (abbreviated HNBR) that is highly resistant to thermal and oxidative deterioration and remains flexible at lower temperatures. Nitrile rubber, like styrene-butadiene rubber and other synthetic elastomers (elastic polymers), was a product of research that took place during and between the two world wars.

Pipes and Tubes - Temperature Expansion

An alloy steel pipe with length 100 feet is heated from 32 to 212oF. The expansion coefficient is 8 10-6 (in/inoF). The expansion of the pipe can be calculated as: dl = (8 10-6 in/inoF) (100 ft) (12 in/ft) ( (212 oF) - (32 oF)) = 1.728 inches. Temperature Expansion of Pipes - Excel Template. Sponsored Links.

EPDM vs Silicone: a simple guide | Knowledge Center

14/1/2019· EPDM beats SBR in tensile strength and resistance to heat aging and weathering. Nitrile butadiene rubber (NBR): Nitrile is king of elastomers when it comes to oil- and fuel-resistance. One attraction to NBR is its stability in low temperatures, with the ability to survive extreme cold of -30˚C/ -22˚F, which EPDM and Silicone can’t match.
