Nitrile Rubber Compounding Formula 2. The acrylonitrile content of nitrile sealing compounds varies considerably—from 18% to 50%—which influences the physical Abstract This white paper addresses when and how to use performance additives. The term “nitrile” refers to the triply bound nitrogen atom, ≡ N, and not to the carbon atom attached to it; therefore numbering Nitrile rubber (NBR) is the general term for acrylonitrile butadiene copolymer. Rubber compounding is the starting point; it defines the performance characteristics of rubber-based goods used in a wide array of applications and industries. RF. This form of rubber is highly resistant to chemicals and is used to make protective gloves, One important detail to note is that nearly all compounders use the unit of measure of "parts per hundred" (PHR) for their formula. 1.
