Rubber NBR Mean?
Rubber NBR, also known as nitrile rubber, or nitrile-butadiene rubber, is an oil resistant rubber used in gaskets in trenchless technology.
As a sealing technology, it is used in water, wastewater, and sewer pipes to protect joints from infiltration and exfiltration. It uses a permanent interior sealing system and to seal offset joints.
Its characteristics ensure that it is proof against high temperatures, oil-based products, and products with high acidity.
Trenchlesspedia Explains Rubber NBR
NBR is an elastomer – a polymer with elastic properties – that is been chemically altered to prevent its degradation in the presence of oils, heat, acids and salts. Used in trenchless technology as a seal, it's wide range of applications provides the trenchless technology contractor with a sealing option for both residential and commercial sewer applications.
Rubber NBR seals may be applied to the ends of a pipe stick at the job site or pipe segments may be purchased with the seals in place.
