Modification of Thermoplastic Materials with NBR
NBR rubber, distributed under the Baymod® N brand, offers excellent resistance to oil, fuel, solvents, and various chemicals. Because Baymod® N is soluble, it can be used in compounding processes, making it suitable for industrial applications such as adhesives and sealants.
Thermoplastics modified with Baymod® N exhibit excellent elasticity and thermoplastic behavior, with good resistance to mechanical stress. It is particularly suitable for use with soft PVC in specialty compounding processes. Since Baymod® N is a polymeric plasticizer, it improves flexibility, enhances oil resistance in PVC formulations, and provides a soft, rubber-like surface finish. Typical applications include coatings, adhesives, and waterproofing membranes.
