LG Chemical NBR 8300 High Acrylonitrile Polymer (discontinued **)
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: NBR 8300 is a copolymer of butadiene-acrylonitrile and the powdered nitrile elastomer manufactured by advanced emulsion polymerization technology of Goodyear and LG Chem. NBR 8300 has excellent compatibility with up to 100 parts of PVC resin, its plasticizers, fillers, heat/UV stabilizers and pigments. Within a PVC matrix, NBR 8300 adds the oil and fuel resistance to PVC compound and also it can improve the impact resistance of PVC. NBR 8300/PVC blend acts like a TPEs and substitutes for vulcanized rubber and TPU in many applications due to its excellent fuel and grease resistance. Applications: NBR 8300 is recommended to use in overflow tubing, vacuum tubing, grommet seals, cable sleeves, gaiters, guard bellows, fuel hoses and seals. In other applications, it is used as modifier for ABS crash pads and also as binder for brake linings. CAS No: 9003-18-3 Information provided by LG Chemical
