DLR Elastomer Engineering Ltd PVCNBR 73 B 3 R3 [75973]

DLR Elastomer Engineering Ltd PVCNBR 73 B 3 R3 [75973] is a 70 Hard PVC Acrylonitrile Butadiene Rubber (PVC/NBR).

  • PVC/NBR has moderate physical properties but good abrasion resistance
  • PVC imparts weather resistance to the NBR making the PVC/NBR product ideal for outside use
  • PVC/NBR is weather, UV and ozone resistant
  • It is extremely versatile, reliable and offers reasonable resistance to petroleum oil, crude oil, water, gasoline and some hydraulic fluids
  • Offering great abrasion and compression set resistance
  • PVC/NBR is a cost-effective sealing solution
  • Because of this, PVC/NBR is a popular sealing material for a wide range of applications
