This report presents a cost analysis of Nitrile Rubber (solid NBR) production from acrylonitrile and butadiene. The process examined is a typical continuous cold emulsion process for producing NBR, containing 33 wt% of acrylonitrile. In this process, an emulsion comprising water, acrylonitrile and butadiene monomers is polymerized into a latex, which is then coagulated to form the Nitrile Butadiene rubber. This report was developed based essentially on the following reference(s): US Patent 5708132, issued to The Goodyear Tire & Rubber Company in 1998; Keywords: Synthetic Rubber, Nitrile Butadiene Rubber, NBR, Buna-N, Perbunan, Acrylonitrile Butadiene Rubber, Nipol, Krynac, Europrene
This report presents a cost analysis of NBR Latex production from acrylonitrile and butadiene. The process examined is a typical cold emulsion polymerization process. In this process, acrylonitrile and butadiene are copolymerized into low solids content NBR Latex. This report was developed based essentially on the following reference(s): Keywords: Synthetic Latex, Nitrile Elastomer, Nitrile Butadiene Latex, NBR Latex, Acrylonitrile Butadiene Copolymer Latex, Nipol, Krynac, Europrene
A study was requested by Manufacturing Engineering to determine what effects marking with nylon (6/6) and Teflon scribes may have on subsequent bonding. Witness panel bond specimens were fabricated by the development lab to test both acrylonitrile butadiene rubber (NBR) to Chemlok and NBR to NBR after controlled exposure. The nylon rod used as a scribe tool demonstrates virtually no bond deterioration when used to scribe lines on either the Chemlok to NBR surfaces or the NBR to NBR interface. Lab test results indicate that the nylon rod-exposed samples produce tensile and peel values very similar to the control samples and the Teflon exposed samples produce tensile and peel values much lower...
