Which elastomer is commonly used for wetsuits?

• A. Natural rubber
• B. Butadiene rubber
• C. Neoprene
• D. Silicone

Answer: (C)

Wetsuits need an elastomer that keeps heat in while still letting you move freely in cold water. Neoprene fits that need because it’s a synthetic rubber made with closed-cell foam that traps air. The trapped air makes it a poor conductor of heat, so insulation is provided, and it also gives buoyancy. This foam structure remains flexible even when cold or under pressure, so you can bend knees and elbows easily while swimming. Neoprene is also durable in saltwater and abrasion-resistant, and it can be made in different densities to balance warmth and flexibility. Other elastomers don’t offer the same combination: natural rubber isn’t water-resistant or stable in cold water, while butadiene rubber lacks the insulating foam structure, and silicone tends to be more expensive and less buoyant for wetsuit use. That's why neoprene is the material commonly used for wetsuits.
