PU foam (polyurethane foam) is a synthetic polymer material produced by the chemical reaction of polyols and isocyanates, creating an expanded cellular structure that combines resilience, uniform density, and shaping ease.
In surfboard manufacturing, PU foam serves as the core material for traditional PU foam blanks, prized for their familiar flex feel and workability.
Its cell structure, density, and curing characteristics influence the board’s weight, durability, and buoyancy.
Shapers refine PU foam selection through tuned density ranges, curing parameters, and compatibility with polyester resin systems that maintain responsiveness, feedback, and control.
