EPS sandwich panel is a composite material with glass fiber reinforced plastic plate on the inner and outer sides, and the sandwich layer is polystyrene foam (EPS). This material is made of high-pressure composite by German vacuum technology, which has the characteristics of smooth surface, bright color and good chemical stability.
Material composition and structure
The main components of EPS sandwich panel include:
FRP plate: FRP plate is used on both sides inside and outside, and there is a layer of gelcoat with excellent performance on the surface, which has good chemical stability and corrosion resistance.
Polystyrene foam (EPS): The sandwich layer is polystyrene foam, which has good thermal insulation performance.
Performance characteristics:
Thermal insulation: EPS sandwich panel has a low thermal conductivity and good thermal insulation performance, which is suitable for various thermal insulation needs.
Chemical stability: The gelcoat on the surface of FRP plate has good chemical stability to the atmosphere, water and general concentration of acid, alkali, salt and other media, with high surface finish, excellent gloss retention, no discoloration, corrosion resistance, sun protection, and anti-aging.
Size customization: The sandwich panel can be up to 3.8 m X 3.6 m (length x width), with a thickness of 25mm, 45mm, 55mm, 65mm, 75mm, 05mm, and can also be made according to the specifications and sizes required by users.
Fields of application
EPS sandwich panels are widely used in insulation/dry cargo compartments, long-span structure roofs, walls, thermal insulation (or fireproof) plants, purification plants, high- and medium-grade combination houses, container houses and other fields.
Pros and cons:
Merit:
Light weight: easy to handle and install.
Good thermal insulation effect: suitable for all kinds of thermal insulation needs.
Good chemical stability: corrosion resistance, sun protection, aging resistance.
Cheap price: The cost is lower compared to other high-performance materials.
Shortcoming:
Flammable: Although it has been improved to meet the Class B flame retardant standard, it is still necessary to pay attention to fire safety.
Limited service life: Compared with some new materials, the service life is short.
To sum up, EPS sandwich panels are widely used in the field of construction and thermal insulation because of their advantages of light weight, good thermal insulation effect and low price, but it is necessary to pay attention to its flammability and take corresponding fire prevention measures.
