Polyurethane (PU)

Introduction to PU foam

When it comes to surfboards, one of the most popular materials used for the core or “blank” is Polyurethane (PU) foam. PU foam is a type of closed-cell foam that is lightweight, durable, and has excellent buoyancy properties. It is formed by mixing two main components, a polyol and an isocyanate, which react to create a foam material.

Glassing process

The glassing process for PU surfboards involves applying a layer of fiberglass cloth to the foam core. This is done by saturating the cloth in polyester or epoxy resin, which is then applied to the foam and allowed to cure. This layer of fiberglass provides strength, stiffness, and protection to the foam core.

Advantages of PU surfboards

There are several advantages to choosing a PU surfboard. Firstly, PU foam has been used in surfboard manufacturing for decades, and its performance characteristics are well-known. PU surfboards are known for their responsiveness and flex, providing surfers with a snappy and lively feel on the waves. Additionally, PU foam is relatively easy to shape, allowing for a wide variety of board designs to suit different surfing styles and conditions. PU surfboards also tend to be more affordable compared to other materials, making them a popular choice among surfers of all levels.

Disadvantages of PU surfboards

However, PU surfboards do have some drawbacks to consider. One of the main disadvantages is their susceptibility to damage. The foam core is relatively soft and can be easily dinged or dented, requiring repairs to maintain the board’s integrity. PU surfboards are also prone to water absorption, and over time, they may become heavier as the foam soaks up water. Additionally, the production process of PU foam involves the use of chemicals that can be harmful to the environment if not properly disposed of.

Sustainability concerns

In terms of sustainability, PU surfboards have raised some concerns. The production of PU foam involves the use of petrochemicals, which are derived from non-renewable fossil fuels. The extraction and processing of these materials have environmental impacts, including air pollution and greenhouse gas emissions. Additionally, the disposal of damaged or old PU surfboards can be problematic, as they are not easily recyclable. As surfers and manufacturers become more conscious of the environmental impact of their equipment choices, there has been a rise in the development and use of more sustainable alternatives to PU foam in surfboard construction.

Expanded Polystyrene (EPS)
