Polymerisation reactor used in the production of styrene butadiene rubber (SBR) is made of__________________?
Correct answer: A. Stainless steel or glass lined steel
- A. Stainless steel or glass lined steel
- B. Nickel clad steel
- C. High silicon cast iron
- D. Aluminium
Explanation
SBR polymerisation equipment commonly uses stainless steel or glass-lined steel because the reactor contents and additives can be corrosive and require clean, non-contaminating surfaces. These materials are more suitable than aluminium or ordinary alloy steels for this service.
