Do you know what kind of sandwich panel is and its characteristics?

Sandwich board sheet:

The sandwich panel is composed of two-layer molded metal panels (or panels of other materials) and a polymer thermal
insulation core that is foamed and cured directly in the middle of the panel, which is easy to install, lightweight,
and efficient. The filling system also uses a closed-bubble molecular structure, which can prevent condensation of
water vapor. Sandwich board is a common product in current construction materials, which is not only good in flame
retardant and sound insulation, but also environmentally friendly and efficient.
At present, the classification of
sandwich panels are: polystyrene sandwich panels or EPS sandwich panels (currently the most widely used variety on
the market); extruded polystyrene sandwich panels or XPS sandwich panels; rigid polyurethane sandwich panels That is
PU sandwich panel; three polyester sandwich panel is PIR sandwich panel; phenolic sandwich panel is PF sandwich
panel; rock wool sandwich panel is RW sandwich panel.

Features of Sandwich Panel:

1. Light weight: The weight of the sandwich panel is less than 24kg per square meter, which can fully reduce the
structural cost.

2. Fast installation: The sandwich panel is light in weight, plugged in, installed and can be cut at will, which
determines its ease of installation, which can improve efficiency and save construction time.

3. Fire protection: The surface material and insulation material of the sandwich panel are non-combustible or non-
combustible materials, which can meet the requirements of fire protection regulations.

4. Fire resistance: Sandwich panels treated with special coatings will last for 10-15 years. Afterwards, they will be
sprayed with anti-corrosion coatings every ten years, and the life of the panels will reach more than 35 years.

5. Beautiful: The clear lines of the sandwich panel can be as many as dozens of colors, which can meet the needs of
any style of building

6. Thermal insulation: commonly used thermal insulation materials include rock wool, glass fiber cotton, polystyrene,
polyurethane, etc., with low thermal conductivity and good thermal insulation effect.

7. Environmental protection and noise prevention: The sound insulation strength of the sandwich panel can reach 40-50
decibels, which is a very effective sound insulation material.

8. Strong plasticity: The sandwich panel can be cut arbitrarily, which can meet the needs of special design.

9. High strength: Using high-strength steel plate as the base material, the tensile strength is 5600 (kg/cm2),
coupled with the most advanced design and roll forming, it has excellent structural characteristics.
