NBR 85 Shore Black
Product Details
Product Introduction
NBR has good mechanical characteristics and better abrasion resistance compared to other elastomers.NBR is not resistant to weathering and the influence of ozone.NBR can be manufactured with an arcyl-nitrile content of 18% to 50%.With reduced ACN content the resistance to all decreases but simultaneously,the flexibility to cold improves.
