What's the raw material for surfing board?

What is the material of the surfboard? Surfing board materials are divided into polyurethane and artificial resin.

1. Polyurethane blank is the core material of surfboard industry since 1960s. Artificial resin and polyester resin can be synthesized into polyurethane. It is generally believed that this material is easier to shape, because it has a smaller crystal structure, so it can be polished with fine powder sandpaper in the shaping process.

Initially, board makers and surfers liked polyurethane because it made surfboards with good reactivity, because polyurethane had strong bending properties. Many surfboard artists love it because it is easy to whitewash or paint surfboards on the foam before pressing them.

But one of the main limitations of PU is its poor resilience. That is to say, the strong bending characteristics of your surfboard will gradually disappear over time and eventually the surfboard will lose its responsiveness. On the other hand, this kind of sheet absorbs water, which will cause foam material to fade and yellowed over time.

2, artificial resin surfboard foam refers to foamed polystyrene or polystyrene. After the main supplier of polystyrene surfboard foam was closed, the Clark foam factory developed foam polystyrene in 2005 when the surfacing world urgently needed surfacing foam core replacement.

Because of its advantageous properties, foamed polystyrene has become very popular as an alternative foam. Polystyrene foam is a lightweight foam that is lighter than polyurethane foam, and its buoyancy is stronger than that of polyurethane. In the final stage of shaping, epoxy resin is covered with polystyrene foam, and a very light, buoyant and firm foam core surfboard is completed. This advantage prevents the surfboard from being damaged or damaged.
