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 the best 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; Thermal insulation inside and outside the walls of cold storage facilities, barracks, grain depots, and civil buildings; Ground construction aspects such as airport runways and plazas; Civil engineering of 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 closed cell rate of over 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring the durability and stability of its insulation performance. Compared with the 80% closed cell rate of foamed polyurethane, its leading advantage is 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 best choice for building insulation.
2. High strength compressive strength
Due to the special structure of XPS board, its compressive strength is extremely high and impact resistance is extremely strong. Depending on the different models and thicknesses of XPS, its compressive strength can reach 150-500Kpa or more, 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 of vehicles.
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 strength 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 without gaps, solving problems such as water leakage, infiltration, frosting, and condensation in other materials.
4. Lightweight texture and easy to use
The completely 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
In long-term use, it does not age, decompose, or produce harmful substances. Its chemical properties are extremely stable and will not degrade due to water absorption or corrosion, causing its performance to decline. It can still maintain its superior performance in high temperature environments. According to relevant information, XPS extruded insulation boards can maintain excellent performance even after 30-40 years of use, without decomposition or mold growth, and without the volatilization of toxic substances.
