Six characteristics of XPS extruded board

  1. Thermal insulation
It has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell rate of its structure has reached more than 99%, forming a vacuum layer, avoiding air flow and heat dissipation, and ensuring the durability and stability of its thermal insulation performance.Compared with the 80% closed cell rate of foamed polyurethane, the leading advantage is self-evident.
  1. High-strength compression
XPS extruded board is a lightweight and high-strength board, and its compressive strength can be as high as 350KPa or more when the density does not exceed 40kg per cubic meter. Good impact resistance can be obtained for use in buildings. The excellent compressive performance of XPS extruded board is almost unchanged even when immersed in water, which is not found in other insulation materials.
  1. Waterproof and moisture-proof
Water absorption is an important parameter to measure thermal insulation materials. After the thermal insulation material absorbs water, the thermal insulation performance decreases. In the case of low temperature, the inhaled water is easy to freeze, which destroys the structure of the thermal insulation material, thereby reducing the compression resistance and thermal insulation performance of the board. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of the sheet is stable and has no gaps, which solves the problems of water leakage, penetration, frosting, condensation and other problems of other materials.
  1. Convenient construction and low cost
Due to its light weight, it is easy to carry, easy to cut, no chainsaw required, and simple to fix. Only iron sheets and wire plastic adhesive polymer mortar can be used to fix it, so the cost of construction can be greatly reduced.
  1. Good stability and corrosion resistance
During long-term use, it does not age, decompose, or produce harmful substances. Its chemical properties are extremely stable, and it will not degrade due to water absorption and corrosion, and its performance will decline. It can still maintain its superior performance in high temperature environments.According to relevant information, XPS extruded insulation board can maintain excellent performance even if it is used for 30 to 40 years, and it will not decompose or mildew, and there is no volatilization of toxic substances.
  1. Product environmental protection
The XPS board has been tested by the relevant state departments and has stable chemical properties, does not volatilize harmful substances, and is harmless to the human body. The production raw materials are environmentally friendly materials and do not produce any industrial pollution. The generated solid waste can be recycled and used, and it is a recyclable environment-friendly product, which is an environment-friendly building material.
