Nitrile Rubber NBR
Nitrile Rubber NBR
Product Description
itrile butadiene rubber (NBR) Introduction
Nitrile rubber is also called nitrile butadiene rubber, NBR, Buna-N and acrylonitrile butadiene rubber. It is a synthetic rubber, and is usually the ideal choice for any product that requires petroleum (oil or gas) resistance.

Benefits & Advantages：
- Resistance to oil and petroleum products.
- Excellent solution for sealing applications, as Nitrile can stretch without losing shape and resist tearing.
- Good compression set.
- Resistance to abrasion, punctures, and tears.
- Resistance to higher temperatures.
- Resistance to abrasion.
- Resistance to water.
- Resistance to gas permeability.
- Can be compounded for service of temperatures up to 250°F (121°C).
NBR application
NBR, due to its excellent oil resistance and physical and mechanical properties, is widely used in the manufacturing of various oil resistant adhesive products, such as O-rings, gaskets, hoses, fuel tank liners, printing drums, oil tank liners, insulated floor panels, oil resistant shoe soles, hard rubber parts, fabric coatings, pipe thread protection layers, pump impellers, wire sheaths, adhesives, food packaging films, rubber gloves, and other fields.
Blending of nitrile rubber
Nitrile rubber can also be used to make equipment linings, industrial rubber rollers, printing boards, textile rubber rings, oil resistant tapes, sponges, gloves, adhesives, modifiers, and heat-resistant rubber parts.
