1. Thermal Insulation Performance: Compared with the closed-cell structure of expanded polyurethane, the superior closed-cell ratio of KAJIA extruded polystyrene boards is self-evident.

2. Excellent water resistance: Due to the non-absorbent nature of the polystyrene molecular structure and the stable, gap-free structure of the board, it effectively addresses issues such as water leakage, permeation, frost formation, and condensation that are common with other materials.

3. High compressive strength: Due to the unique structure of extruded polystyrene (XPS) boards, they exhibit excellent compressive strength and impact resistance. Depending on the specific grade and thickness of the XPS board, the compressive strength ranges from 150 to 700 kPa, enabling them to withstand the loads of various types of cargo.

4. Stable chemical properties: During prolonged use, extruded polystyrene boards do not age, decompose, or release harmful substances; their chemical properties remain stable. They are resistant to degradation caused by water absorption and corrosion, ensuring consistent performance over time. Moreover, they maintain their superior performance even in high-temperature environments.

5. Durability: According to relevant literature, extruded polystyrene boards can maintain excellent performance even after 30 to 40 years of service, without undergoing decomposition or mold growth and without emitting any toxic substances.

6. Convenient processing and application: The closed-cell foam structure and honeycomb-like physical structure of extruded polystyrene boards give them a lightweight nature, making them easy to transport, readily cuttable, resistant to breakage, and simple to process and install.

7. A commendable product: KEJIA extruded polystyrene is made from pure polystyrene, which boasts stable chemical properties. During use, it does not volatilize any harmful substances; even at high temperatures, it emits no hazardous gases and will neither decompose nor mold. It is harmless to humans and is therefore ideal for refrigerated food transportation.
