Polyurethane vs. Neoprene: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Polyurethane is a versatile polymer used in foams, elastomers, and coatings; Neoprene is a synthetic rubber known for its chemical stability and flexibility.
Key Differences
Polyurethane is a polymer composed of organic units joined by urethane links, often used in foam products and surface coatings. Neoprene, on the other hand, is a synthetic rubber developed as an oil-resistant substitute for natural rubber, commonly used in wetsuits and gaskets.
