Material Notes:
Acrylonitrile Butadiene Rubber (NBR)Characteristics: KOSYN KNB is copolymer of high oil resistance and chemical resistance made from acrylonitrile and butadiene by the cold emulsion polymerization. KKPC NBR has superior working properties such as roll winding properties, compounding dispersibility and extrasApplications: Rubber products having elevated oil-resistance and cold-resistance such as packing, gasket, shoe soles, home appliances.Additional Notes: Bound Acrylonitrile: 28%Compound Properties: NBR 100, ZnO 3, Stearic Acid 1, HAF Black (IRB#7) 40, Accelerator TBBS 1, Sulfur 1.5, Total: 146.5Volume Change: 2%This product is so sensitive to sunlight and humidity that it can be tarnished and caused deterioration of quality if exposed. It is recommended to store it in cool and shady area lest it should be exposed to direct sunlight. Do not expose to incompatible materials or contaminants.Data provided by Korea Kumho Petrochemical Co., Ltd.
