Shanghai Green fish extruded insulation board is made of 100% BASF crystal-grade raw materials and is produced using internationally advanced fluorine-free and bromine-free technology. Without any pigments, additives, or additives, the imported production line of Bellstov in Germany is used. In production, the high-performance hard foam plastic with a honeycomb-like closed-cell structure is made by heating and extrusion by special processes under the conditions of the ISO quality management system. The interconnected walls of these honeycomb structures have a certain thickness and there will be no gaps at all. Therefore, the uniform structure formed by the extrusion process makes the product have superior thermal insulation and thermal insulation, good moisture resistance and high compression resistance.

　　The performance characteristics of white crystal panels are as follows:

　　1. Excellent thermal insulation

　　It has the characteristics of high thermal resistance, low linearity and low expansion ratio. The closed cell rate of its structure reaches more than 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring the durability and stability of its thermal insulation performance. Compared with the closed cell rate of 80% for foamed polyurethane, the leading advantage is self-evident. Practice has proved 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 the best choice for building insulation at present.

　　2. Excellent high-strength compressive resistance

　　Due to the special structure of XPS board, its compressive strength is extremely high and its impact resistance is extremely strong. According to the different models and thickness of XPS, its compressive strength reaches more than 150-500Kpa, and can withstand ground loads of various systems. It is widely used in geothermal engineering, expressways, airport runways, square grounds, large cold storages, and interior decoration insulation.

　　3. High-quality water repellent and moisture-proof

　　Water absorption is an important parameter for measuring insulation materials. The insulation performance of the insulation material decreases accordingly after absorbing water. At low temperatures, the inhaled water is very likely to freeze, destroying the structure of the insulation material, thereby reducing the compression and insulation performance of the sheet. Since the polystyrene molecular structure itself does not absorb water, the plate molecular structure is stable and has no gaps, it solves problems such as water leakage, penetration, frost, and condensation of other materials.

　　4. Light texture and easy to use

　　The fully closed-cell foamed chemical structure of XPS plate and its honeycomb physical structure make it lightweight and high-strength, which is easy to cut and transport, and is not easy to break and easy to install.

　　5. Good stability and corrosion resistance

　　During long-term use, it does not age, decompose, or produces harmful substances. Its chemical properties are extremely stable and will not degrade due to water absorption and corrosion, causing its performance to decline. It can still maintain its superior performance in high temperature environments. The Blue Fish XPS extruded insulation board is durable, has stable performance for 50 years, and will not decompose or mold, and there is no volatilization of toxic substances.

　　6. Product environmental performance

　　The XPS plate has stable chemical properties and does not volatile harmful substances and is harmless to the human body. The raw materials are made of environmentally friendly materials and do not cause any industrial pollution. This product is an environmentally friendly building material.
