The main features of the internal structure of XPS extruded panels include:
1.1 Closed cell honeycomb structure
● Description: xps extruded panel has a closed cell honeycomb foam structure. Each cell is surrounded by other cells and is not connected to other cells.
●Advantage: The closed-cell structure makes the extruded panel almost non-absorbent and has a very low water absorption rate, thus preventing the intrusion and expansion of water, and maintaining long-term heat preservation.
1.2 Uniform distribution of high density
●Description: Extruded panels are made through continuous extrusion process during production, which makes the bubble holes uniformly distributed and the walls between the holes are thicker.
● Advantage: Uniform density and bubble hole distribution make the extruded board have stable physical properties, such as low thermal conductivity and high compressive strength.
2 Performance characteristics
2.1 Excellent thermal insulation
Principle: Due to the closed cell structure, the thermal conductivity of the extruded plastic board is very low. Air is a good heat insulator, and the closed cell structure effectively reduces heat conduction.
● Effect: This structure provides excellent thermal insulation performance and is suitable for use in application scenarios such as building exterior walls, floors, roofs and other thermal insulation.
2.2 High strength and compression resistance
●Principle: The closed-cell structure and high density of the extruded plastic sheet give it high compressive strength.
●Effect: Even under high loads or long-term use, the extruded plastic board maintains its shape and performance, making it suitable for application scenarios that require pressure, such as floors or garage roofs.
2.3 Lightweight and easy to use
● Principle: The overall density of the extruded panel is low due to the foam structure.
●Effect: Light weight makes extruded plastic panels easier to handle and install during construction, reducing construction difficulties and transport costs.
2.4 Good stability and corrosion resistance
●Principle: The closed-cell structure of the extruded plastic board is not easy to absorb water, so it is also not easy to be affected by moisture and humidity. Its chemical stability is strong, and it does not react to many kinds of chemical substances.
●Effect: It has good corrosion resistance and aging resistance, and can be used for a long time in various environments without easy degradation.
3. Application fields
●Building thermal insulation: widely used in the thermal insulation treatment of building exterior walls, roofs and floors.
● Cold storage and cold storage equipment: due to its excellent heat insulation, it is suitable for the insulation layer of cold storage and cold storage equipment.
● Underground engineering: used in basements, foundations and other engineering projects that require pressure and moisture resistance.
Summary
The closed-cell honeycomb structure of xps extruded panel gives it excellent thermal insulation performance, high strength and compression resistance, lightweight and convenient construction characteristics, and excellent corrosion resistance and stability. These properties make it a very effective and reliable material for building insulation and other applications requiring thermal insulation.
