NR (natural rubber)

NR (natural rubber) is a common rubber material with good physical and chemical properties and processing properties, and is often used to manufacture rubber seals.

 

NR rubber seals are seals made from natural rubber and have good elasticity and wear resistance. Natural rubber is extracted from the latex of the rubber tree and is processed and vulcanized to form an elastomeric material. NR rubber seals are widely used in various industries and fields to provide effective sealing and protection functions.
