Nitrile Rubber

[fildisi_empty_space][fildisi_divider line_type=”dashed-line”][fildisi_empty_space]

Nitrile rubber is a butadiene and acrylonitrile copolymer, both hot- and cold-polymerized polymerized types are available. All having a non-staining antioxidant. NBR is ideal for applications that require excellent oil and fuel resistance.

It presents chemical resistance to organic substances such as aliphatic oils and nonpolar solvents. Increasing the acrylonitrile content, increases its oil, fuel and solvent resistance, reducing the acrylonitrile content, increases low temperature resilience and flexibility.

Clean NBR and XNBR

[fildisi_empty_space][fildisi_divider line_type=”dashed-line”][fildisi_empty_space]

The advantage of the CLEAN line over traditional nitrile rubber is its reduced mould fouling , allowing for more injection cycles with less stops for mold maintenance. Excellent processability in transfer and injection molding. Carboxylated nitrile rubber improves traction, abrasion, tear, and modulus resistance.

NBR PVC

[fildisi_empty_space][fildisi_divider line_type=”dashed-line”][fildisi_empty_space]

NBR/PVC compounds are homogenous butadiene and acrylonitrile copolymer blends with PVC that uses CA/ZN based stabilizers. NBR/PVC blends are recommended for applications that require good resistance to the elements and organic liquids, such as aliphatic oils and nonpolar solvents. Its main advantage over traditional nitrile rubber is its ozone resistance.
