What Are the Performance Characteristics of Extruded Board?

 The full name of the extruded board is extruded polystyrene foam board or extruded board for short, also known as XPS board. It is a material that is continuously extruded and foamed through a special process. The hard film formed on the surface is uniform, the inner closed-cell foams continuously and uniformly, and the honeycomb structure is formed. It has high compression, lightweight, no water absorption, air permeability, and resistance features such as abrasiveness and non-degradation.

It is especially suitable for heat insulation, heat preservation, and moisture-proof treatment of buildings. Through positioning, the overall size of the template and the front and rear distance of the section can be adjusted to adjust the layout width, and then the positioning alignment can be adjusted to adjust the width of the card.

1. Thermal insulation

The sealing rate of the extruded board structure is greater than 99%. The vacuum layer is formed to avoid airflow and heat dissipation to ensure the durability and stability of its thermal insulation performance. The sealing rate of foamed polyurethane is only 80%, which proves that 20mm The thermal insulation effect of thick XPS extruded thermal insulation board is equivalent to that of 50mm thick expanded polystyrene and 120mm thick cement perlite, which is currently the first choice for building thermal insulation.

2. Hydrophobic and moisture-proof

After the thermal insulation material absorbs water, the thermal insulation performance decreases. The inhaled water is easy to freeze at low temperatures, which destroys the structure of the thermal insulation material and reduces the compression and thermal insulation performance of the thermal insulation board. However, because the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable. There is no gap, which solves the problems of leakage, penetration, freezing, and condensation of other materials.

3. Has high compressive strength

Due to the special structure of the extruded board, its compressive strength is very high and its impact resistance is very strong. The compressive strength is above 150~500kpa, can withstand the ground load of various systems, and is widely used in geothermal engineering, highways, airport runways, square floors, large-scale cold storage, automobile interior decoration, and insulation, and other fields.

4. Has good stability and corrosion resistance

The chemical properties of the extruded board are extremely stable and will not age, decompose, or produce harmful substances when used for a long time. Even after 30 years of use, it can still maintain excellent performance, will not rot, mold, and will not volatilize toxic substances.

5. Reliable

The closed-cell foaming chemical structure and its honeycomb physical structure is light in texture and easy to use. It has the characteristics of high strength, easy to cut and transport, not easy to damage and install.

6. Product environmental performance

The extruded board has been inspected by relevant national departments, and its chemical properties are stable, non-volatile harmful substances, and harmless to the human body. The raw materials produced are environmentally friendly materials and do not produce any industrial pollution. It is an environmentally friendly building material.

Introduction to Glass Wool(Part 2)

  The sound absorption performance of centrifugal   glass wool  is also closely related to the installation conditions. When there is an air layer behind the glass wool board, the sound absorption effect is similar to that of a glass wool board with the same thickness without an air layer. In particular, the sound absorption performance of medium and low frequency will be greatly improved than the material is attached to the hard bottom surface. The sound absorption coefficient will increase with the increase of the thickness of the air layer, but the effect will not be obvious after increasing to a certain value. Using glass wool of different bulk density is stacked together to form a form of gradually increasing bulk density, which can obtain a greater sound absorption effect. For example, stacking a 2.5cm thick 24kg/m3 cotton board with a 2.5cm thick 32kg/m3 cotton board will have better sound absorption than a 5cm thick 32kg/m3 cotton board. The 24kg/m3 glass wool boa...

Application Field of Extruded Board

The extruded board is a high-quality and cheap construction insulation material in the construction industry. It can not only be used as wall insulation but also has an excellent performance in other aspects. The following  extruded board manufacturers  will tell you what are the application areas of extruded boards? 1. The extruded board can be used as floor installation auxiliary material The floor mat used in the floor mats installed in the suspended floor is extruded board. Its paving is very convenient and can prevent the floor from being damp, deformed, and moth-eaten. The sound insulation and heat preservation effects are also very obvious, and you can feel a little softness when you step on the floor, which is very comfortable. Using this kind of extruded board mat to pave the floor can protect the ground from damage. It can be used when installing composite flooring, solid wood multilayer flooring, and solid wood paint-free and planer-free flooring. 2. Make a...

Demand For Glass Wool In The Market

Glass Wool  has good molding, low thermal conductivity, thermal insulation, and good attraction. It is widely used in building insulation. It is used for thermal insulation, sound absorption and noise reduction of industrial buildings, warehouses, public facilities, exhibition centers, shopping malls, and various indoor playgrounds, sports venues and other buildings. Glass Wool Glass wool insulation materials are also very helpful for building energy saving. With statistics, glass wool can achieve energy saving rate of 55%. Glass wool is based on the principles of vacuum insulation and microporous insulation. Using glass fiber as the core material, the thermal conductivity can reach 0.036W / (mK) or less. The thermal insulation performance is 6 to 10 times that of traditional thermal insulation materials. Products from raw materials collection to the entire production process are combined with environmental protection requirements, non-toxic and harmless; not only can ...
