XPS extruded insulation board production line (carbon dioxide CO2 foaming)

XPS extruded polystyrene foam board (XPS) has a perfect closed cell honeycomb structure and is currently recognized as an insulation material in the market. It uses recycled EPS polystyrene board granulation as the main raw material to complete the product production process of extrusion foaming, shaping, traction and cutting. Its density, water absorption, thermal conductivity and steam permeability coefficient are lower than other types of plate thermal insulation materials, so it has the characteristics of good strength, light weight, impermeable, corrosion resistance, aging resistance, low price, etc., and is widely used in roof thermal insulation systems; Insulation and thermal insulation of walls inside and outside cold storage, barracks, grain depots, and civil buildings; Ground construction aspects such as airport runways and squares; Civil engineering for highways and railways; In the partition system of buildings such as apartments, office buildings, and factories, etc.

Performance characteristics:

1. Thermal insulation

It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a closure rate of over 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring its insulation performance is long-lasting and stable. Compared to the 80% closure rate of foamed polyurethane, its advantages are self-evident. Practice has proven that the insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick foamed polystyrene and 120mm thick cement perlite. Therefore, this material is currently the preferred choice for building insulation.

2. High strength compressive strength

Due to the special structure of XPS board, it has extremely high compressive strength and strong impact resistance. According to different models and thicknesses of XPS, its compressive strength can reach 150-500Kpa or above, and it can withstand ground loads of various systems. It is widely used in geothermal engineering, highways, airport runways, square floors, large cold storage, and interior decoration and insulation fields.

3. Hydrophobic and moisture-proof

Water absorption rate is an important parameter for measuring insulation materials. After absorbing water, the insulation performance of the insulation material decreases. At low temperatures, the absorbed water is prone to freezing, which damages the structure of the insulation material and reduces the compressive and insulation performance of the board. Due to the fact that the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable and has no gaps, solving problems such as water leakage, penetration, frost formation, and condensation in other materials.

4. Lightweight and convenient to use

The fully closed cell foaming chemical structure and honeycomb like physical structure of XPS board make it lightweight, high-strength, easy to cut, transport, and not easily damaged, and easy to install.

5. Good stability and corrosion resistance

During long-term use, XPS extruded insulation boards do not age, decompose, or produce harmful substances. Their chemical properties are extremely stable and do not degrade due to water absorption and corrosion, resulting in a decrease in performance. They can still maintain their superior performance in high temperature environments. According to relevant information, even after 30-40 years of use, XPS extruded insulation boards can still maintain excellent performance without decomposition or mold, and there is no volatilization of toxic substances.
