Styrene Butadiene Rubber (SBR) has excellent impact strength, good resilience, tensile strength, abrasion resistance, and ageing stability. It maintains flexibility at lower temperatures. SBR rubber competes with natural rubber (NR), and is also used in blends with NR.

The advantage for SBR:

• Good physical properties
• Excellent abrasion resistance
• Good electrical isolating properties
