NR-SBR Red Star 40

RED STAR is a very abrasion-resistant and flexible rubber. It is resistant to strong bases and it is reasonably resistant to acids. RED STAR is not weather and ozone resistant and is not resistant to oil and gasoline. Lower elongation at break than Linatex but a more economical alternative in many cases.
