Heat Resistance High Density NBR Foam Close Cell Nitrile Rubber Material
NBR, also known as Buna-N, Perbunan, acrylonitrile butadiene rubber, nitrile rubber, is a synthetic rubber copolymer of acrylonitrile and butadiene. NBR is afamily of unsatruated coplymers of 2-propeneitrile and various butadiene monimers (1,2,-butadiene and 1,3-butadiene). It has various kinds of applications. Benefits of NBR Foam Rubber include:
1.Impact and vibration absorption
2.Weather and chemical resistance including splash resistance to oils and fuels
3.Acoustic and thermal insulation properties
4.Buoyancy with low water absorption
5.Suitability for thermo-forming and thermo-moulding
