Epoly has a quiet, yet alive feeling. EPS is very light and “frisky” yet can be too sensitive to surface conditions when the wind comes up or if the surf gets bigger. PE is the traditional construction with a polyurethane core and polyester skin. Epoxy resin on a polyurethane blank results in a board that is whiter, brighter and doesn’t yellow to the extent of a traditional PE board. Also, Epoxy is known for its higher bonding capabilities overall. An epoxy’s relative strength can hold up to 2,000 lbs. per square inch, while a polyester resin can hold less than 500 lbs. per square inch. We’ve been building Epoly boards for years and with more and more positive feedback we feel it’s the optimum direction for resilient yet affordable surfboard construction.
