Natural rubber NR (Natural Rubber) is made of latex collected from rubber trees and is a polymer of isoprene. It has good wear resistance, high elasticity, breaking strength and elongation. In the air easy to aging, in the heat and viscosity, in mineral oil or gasoline easy to expand and dissolve, alkali resistance but not resistant to strong acids. ·
Is the production of tape, hose, rubber shoes raw materials, and suitable for the production of damping parts, in the automotive brake oil, ethanol and other hydroxide liquid used in the products.
Butyl benzene gum S B R Butyl benzene gum (styrene butadiene copolyme) is a co-polymer of butadiene and styrene, compared with natural glue, uniform quality, less foreign body, but the mechanical strength is weaker, can be mixed with natural adhesive use.
