The Custom Nitrile Rubber Molding Experts
Chemical Designation: Butadiene Acrylonitrile (NBR)
For applications requiring oil resistance, nitrile rubber molding is an excellent choice. Through the injection molding nitrile rubber process, this material demonstrates exceptional resistance to mineral, vegetable, and petroleum oils, as well as solvents and hydraulic fluids. Nitrile rubber offers superior heat resistance, resilience, and abrasion resistance while maintaining a low permanent set. As a stretchable and durable elastomer, nitrile is a reliable option for demanding applications.
However, nitrile rubber molding should not be used for applications where oil resistance is not a major concern due to its cost. It shows poor resistance to acetone, ketones, hydrocarbons, and 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
- Heat resistant
- Water Resistance
- Low gas permeability
Applications of Nitrile Rubber Molding
Qualiform Proprietary Blend
In addition to our Nitrile materials, Qualiform offers 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.
