LG Chemical NBR 7030 High Acrylonitrile Polymer
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: NBR 7030 is a mechanically fully-fluxed polyblend of 70 parts medium-high acrylonitrile rubber and 30 parts polyvinylchloride resin. Since NBR 7030 are prefluxed, normal temperature for rubber can be adopted during mixing and subsequent factory operations. NBR 7030 has sufficient stabilizer for normal aging conditions and can be processed with normal mixing procedures. It has higher compound strength, relatively better physical properties and good processability for extrusion, providing smooth surface on the resultant products. Applications: These properties make NBR 7030 ideally suited for hose, wire, cable and roll application. NBR 7030 is excellent in resistance to abrasion, ozone, oil, fuel and solvent. It is suggested for use in wire & cable jackets, rolls, shoes, belts and hose (fuel hose, automotive and industrial hoses) CAS No: 9003-18-3 Information provided by LG Chemical
