What is EPS foam surfboard?
Expanded Polystyrene (EPS) Surfboard Blanks Expanded Polystyrene (EPS) foam is also known as beaded foam and features a closed cell core. EPS is made using small expandable beads that inflate with heat, and then are placed into a mould, where they expand to fit the shape. EPS is a closed-cell foam, meaning there are no holes or spaces between the cells. Because of this make-up, EPS is highly resistant to bending and compression, so it works well in load-bearing situations. EPS is an extremely strong material for construction projects that is not subject to degradation over time.EPS foam is lighter and stronger than Polyurethane foam blanks. It consists of small beads of polystyrene expanded with steam and fused together under high pressures. Greenlight’s EPS blanks are engineered with a special high energy bead-bond formula for the optimal strength, flex, and shape-ability of the blank.Moisture Resistance: EPS foam is resistant to moisture, preventing mold and mildew growth. Durability: Despite its lightweight nature, EPS foam is remarkably durable, capable of withstanding impact and compression.Problems with expanded polystyrene Because they are not readily recyclable, the materials end up in landfills, waste-to-energy facilities, or the environment. EPS materials are extremely brittle and break easily into tiny pieces. These small pieces scatter in the wind and contaminate the environment.
Which is better poly or EPS surfboards?
EPS has better structural integrity, protecting it against hard impacts and preventing dings to your surfboard compared to PU. If there’s one downside with EPS, it is the cost of producing these boards, which makes them the priciest of all surfboard options. Although some EPS manufacturers attempt to disguise it, EPS absorbs more water than XPS. Absorbed water results in lost insulation power (R-value). Lost R-value results in reduced performance.While XPS insulation has less moisture absorption than EPS in a test environment, the numbers do not equate to a real-world application difference in performance. Years of real-world research has shown the in-situ moisture performance of EPS and XPS to be very similar.EPS versus XPS Boards XPS boards offer you all the advantages of EPS boards but come on top in terms of strength and water absorption resistance properties. EPS has better structural integrity, protecting it against hard impacts and preventing dings to your surfboard compared to PU.Cons of EPS: More fragile and prone to damage during installation and handling. Lower R-value per inch of thickness compared XPS (3. EPS, compared to 5 for XPS) More susceptible to water absorption, which can reduce its insulation performance and potentially cause structural damage.Unlike PE Core, EPS Core is stiffer, offering better responsiveness and speed through turns. This option is ideal for riders looking for more dynamic performance and a faster feel on the wave. The EPS Core works well in a wide range of conditions, but is particularly suited to colder water and faster waves.
What is the difference between foam board and EPS?
The major difference between Styrofoam and EPS foam blocks is that Styrofoam is made from extruded polystyrene (XPS) while EPS foam blocks are made of expanded polystyrene. EPS is generally cheaper than XPS. So if you’re looking to insulate a large area on a budget, EPS foam board might be the way to go. It’s still highly effective for general insulation and offers solid R-value at a fraction of the cost.EPS foam is popular for its use in packaging, disposable food containers, insulation for buildings, and craft products. XPS foam is often used in insulation boards for roofs, walls, and foundations in commercial and residential construction.In summary, the choice between EPS and XPS will depend on a variety of factors, including cost, insulation requirements, moisture concerns, and structural requirements. EPS is generally the more affordable and higher performing option in terms of insulation, while XPS is more durable and resistant to water damage.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.XPS and EPS are both popular insulation types because they both have low thermal conductivity. EPS has pockets of air trapped inside the foam board, so XPS typically outperforms EPS. High-density EPS is closer in performance to XPS, but XPS still usually performs better.
Is EPS foam good?
Thermal Efficiency and Energy Savings As such, EPS foam makes for a good insulator against heat and cold. The energy efficiency of insulation products is measured with what is called its ‘R-value’. The higher the R-value, the better it acts as an insulator and the addition of a plastic or foil layer can heighten this. EPS insulation is known for its durability and longevity. When installed correctly and protected from direct exposure to sunlight and mechanical damage, it can last for the lifetime of the building, often exceeding 50 years. Its inert nature means that EPS does not degrade over time under normal conditions.In fact, it can take up to 500 years for EPS foam to degrade in a landfill! When EPS foam does break down, it’s usually in the form of microplastics, which has an incredibly negative impact on the environment.A moisture-resistant and highly breathable insulation material, EPS brings critical performance qualities to the table.EPS (expanded polystyrene) geofoam, when installed and protected, can last for a very long time, with estimates ranging from 50 to 100 years or even potentially indefinitely, due to its resistance to moisture, environmental damage, and chemical degradation.
What is EPS foam board used for?
Expanded polystyrene (EPS) is a lightweight and rigid foam material. It is a material of choice for the packaging and construction industry. It provides cost-effective solutions and energy-efficient insulation. It also acts as a cushion transport packaging material for shock-sensitive goods. Surfboards are made from (and Greenlight sells) two types of foam blanks. EPS Foam Blanks – EPS stands for Expanded Polystyrene. EPS foam is lighter and stronger than Polyurethane foam blanks.EPS (expanded polystyrene) is not waterproof per se, but does not have a capillary effect. This means that the insulation does not absorb water, and water can only penetrate if forced to do so by external pressure.EPS foam is not waterproof The board is fine when it’s closed and it’s new and whole. But as soon as you put it in the sun or somewhere warm, air expands. So there is a pressure build up inside the board.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.Expanded Polystyrene (EPS) Surfboard Blanks Expanded Polystyrene (EPS) foam is also known as beaded foam and features a closed cell core. EPS is made using small expandable beads that inflate with heat, and then are placed into a mould, where they expand to fit the shape.
How long does EPS foam last?
When EPS is utilized for insulating walls it can offer durable thermal protection that can last anywhere from 30 to 50 years. ICFs utilize EPS in their construction which can last indefinitely as it is shielded from substances and external elements that cause deterioration over time. Floor Insulation Brands like Kingspan and Ecotherm are popular choices for their durability and efficiency.

This type of insulation stands out for its moisture resistance and high thermal resistance, which contribute to its longevity and effectiveness in various applications.
Is EPS foam durable?
Products made from EPS are typically water resistant, tough and give very high impact resistance. The air-filled structure has long term stable thermal conductivity, is non-toxic and chemically inert. The good news with EPS is that it is naturally moisture resistant. This doesn’t mean it is completely waterproof, but it does resist moisture thanks to its closed-cell design. EPS’ moisture resistant properties also make it resistant to mold and algae.While EPS is not entirely waterproof, it does exhibit water-resistant characteristics due to its closed-cell structure. This structure makes it highly resistant to moisture absorption, making it suitable for use in environments with high humidity or occasional exposure to water.UV Exposure and Protection EPS insulation is very durable but may dust or discolor its surface if exposed to prolonged UV sunlight. For optimal performance, EPS should be covered or finished when exposed to sunlight for long periods.Products made from EPS are typically water resistant, tough and give very high impact resistance.
