Butadiene/acrylonitrile
Paracril NBR powder is supplied by the company. Nitrile rubber is a polar elastomer that can be blended with other elastomers and thermoplastics. The predominant thermoplastic blend with NBR is with PVC. These two polymers form a miscible blend which imparts ozone resistance to the NBR and flexibility to the PVC. The NBR acts as a high molecular weight plasticizer to replace the normal monomeric plasticizer used in PVC compounds. This benefits the oil resistance, fuel resistance, tear strength, abrasion and flex resistance, according to the company. Since the NBR is not extractable versus the fugitive monomeric plasticizer, it will remain after heat aging, oil and fuel immersion, yielding better aged properties and low temperature performance after aging. The lower level of monomeric plasticizer also is said to reduce cracking of adjacent thermoplastics due to migration of the monomeric plasticizer to the thermoplastic, which swells the plastic, causing crazing. NBR powder is used in friction products such as brake pads and clutch discs. ()
