Epoxy vs. Poly Surfboards: Understanding Surfboard Construction
EPS Epoxy and PE Polyurethane are two different types of materials used to make surfboards. Both have their advantages and disadvantages when it comes to surfboard construction.
Here at Global Surf Industries, we stock a range of both epoxy and poly surfboards. Here we’ll help to break down the differences between them to help you understand their construction, and therefore decide which type is right for you
Poly vs. Epoxy Surfboards: What’s the Difference?
Both epoxy and polyurethane have been used for years in the construction of surfboards, and both have their pros and cons. So what’s the difference?
EPS Epoxy (Expanded Polystyrene) is a lighter and more durable material than traditional PU (Polyurethane) foam. EPS foam is made up of tiny beads that are fused together to form a lightweight, closed-cell foam core. The foam is then coated with an epoxy resin, which provides additional strength and rigidity to the board.
EPS boards tend to be more buoyant and responsive than traditional PU boards, making them popular among surfers who want a high-performance board. Here at Global Surf Industries, we make a number of epoxy surfboards in this technology in our SUP range, as well as our SLX (Super Lightweight Epoxy) boards and our ES (Epoxy Soft) boards.
What Does PU Stand For?
PE or PU stands for Polyurethane, a type of foam used in surfboard manufacturing. It is a closed-cell foam that is shaped into the desired surfboard shape and then coated with polyester resin
The resulting board is known for its flexibility and responsiveness, which make it a popular choice for surfers of all levels.
The bulk of the GSI range is still made of this PE resin Polyurethane blank combination. We still find the PE PU combination very suitable to make boards that hold their performance characteristics for a long time.
Which is Better? Epoxy vs. Poly Surfboards
People often ask us which is best, but there is no correct answer to this question. It’s a matter of trying each of the technologies out and finding one that suits you the best.
The choice between the two types of surfboards ultimately depends on the surfer's preferences, skill level, and the conditions they will be surfing in. This could come down to the conditions on the day.
Epoxy vs. Poly Surfboards: How to Decide Which is Right for You
In summary, the main differences between EPS Epoxy and PE Polyurethane surfboards are weight, durability, and responsiveness. EPS Epoxy boards tend to be lighter, more durable, and more responsive, while PE Polyurethane boards tend to be more flexible and responsive.
