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.

Do You Know What the Use of Glass Wool Insulation Material Is?

  From the present day, we can see that   Glass Wool   insulation material is used in many aspects of daily life. Its thermal insulation properties make it widely used in daily life or work. The most common is that in colder winters, people can use this product to wrap their own water pipes. This can ensure that their water pipes are not frozen, and then the water between them can be kept flowing for as long as possible.  Glass Wool Because of its shearability, glass wool insulation materials can be trimmed according to their own needs, and products of different sizes can be cut and used in different places. For example, in this relatively cold place in the Northeast, people can wrap this product on their own roofs, make their houses adhere to a certain temperature, and fully play the role of heat insulation of this product, bringing comfort and comfort to their lives. convenient. In addition, glass wool insulation materials are also used more locally. With the extensive use of this in

Neoprene vs EPDM: What's the Difference?

  Both neoprene and   EPDM   are materials used in the manufacture of conveyor belt systems. While neoprene is most commonly used in the industry, many companies are turning to EPDM because using it overcomes many of the challenges associated with using neoprene.   What is neoprene? Neoprene is made through the polymerization of chlorine. Characterised by its chemical stability, flexibility over a wide range of temperatures and resistance to degradation, the material was originally intended as a petroleum-based alternative to natural rubber.   Its durability and flexibility make neoprene suitable for a wide range of everyday products - such as sports and medical equipment, technical coverings and sleeves, diving suits and safety gloves - as well as for a variety of outdoor applications - including as hoses, gaskets, seals, and gaskets. -including as hoses, gaskets, seals, coatings and linings.   Huamei  EPDM rubber foams  include semi-closed cell supersoft and supersoft foams; closed c

What Is the Difference Between Extruded Board and Foam Board?

  Extruded plate  (XPS), based on polystyrene resin as raw material, through a special process of continuous extrusion foaming molding hardboard, its internal structure for independent closed bubbles, is one kind has high pressure, water absorption, moisture, breathable, lightweight, corrosion resistance, long service life, low coefficient of thermal conductivity, excellent environmental protection heat preservation material performance. Extruded polystyrene (XPS) insulation board is widely used in wall insulation, flat concrete roof, and steel structure roof insulation, low-temperature storage ground, parking platform, airport runway, highway and other fields of moisture-proof insulation, and control ground frost heave. 1. Excellent and long-lasting thermal insulation The extruded board has a thermal conductivity of 0.028w/MK, which has the characteristics of high thermal resistance and low linear expansion rate. Its thermal conductivity is far lower than other insulation materials su
