KKPC KOSYN KNB 25H Acrylonitrile Butadiene Rubber (NBR)
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
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. Our NBR has superior working properties such as roll winding properties, compounding dispersibility and extrusion properties. Also, it is easily processed on account of the excellent vulcanization properties.

Applications: 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: 146.5
Volume Change: 3%

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.
