The Custom Nitrile Rubber Molding Experts

Chemical Designation: Butadiene Acrylonitrile (NBR)

We recommend nitrile rubber molding when oil resistance is required. It is resistant to mineral, vegetable and petroleum oils, solvents and hydraulic fluid. It is able to resist heat and exhibits good resilience and abrasion resistance, as well as low permanent set. Nitrile is a resilient and stretchable polymer/ elastomers.

Do not use Nitrile for applications where oil resistance is not a major concern because of its cost. It demonstrates a poor resistance to acetone, ketones, hydrocarbons and the ozone.

What is Nitrile Rubber?

Nitrile rubber, also known as nitrile butadiene rubber (NBR), is a synthetic rubber with excellent resistance to petroleum-based oils, mineral oils and vegetable oils. Nitrile rubber is more resistant than natural rubber to oils, acids and heat aging. Furthermore, Nitrile offers superior abrasion resistance and properties for metal adhesion.

Nitrile is an incredibly versatile rubber material. However, it has poor weathering properties. As a result, it is not recommended for use in applications involving exposure to ozone, esters, ketones, aldehydes and chlorinated/nitro hydrocarbons.

Advantages of Nitrile Rubber

  • Ideal for sealing applications
  • Good compression set
  • High abrasion resistance
  • High tensile strength

Qualiform Proprietary Blend

In addition to our Nitrile materials, Qualiform offerss a proprietary blend with reinforcing fibers. We directly blend reinforcing fibers into the Nitrile rubber. As a result, the Nitrile has increased resistance to abrasions and impacts as well as improved durometer, toughness and performance. Qualiform also offers this blend for our other available materials.

Nitrile Molding
Due to the nitrile within the polymer, this form of synthetic rubber molding excels at resistance to oil, fuel, and other chemicals while maintaining flexibility.
