High Compressive XPS Foam Board for Cold Truck

The primary purpose of the XPS foam board in refrigerated trucks is to regulate air circulation and partition the vehicle into distinct temperature zones. Extruded XPS foam boards come in two varieties: standard extruded XPS foam boards and temperature-controlled extruded XPS foam boards. The latter is equipped with temperature control devices and fans to precisely manage the temperature within the designated zones.

Material Composition

The High Compressive XPS Foam Board for Cold Truck is manufactured using a high-density extruded polystyrene formulation specifically engineered for demanding load-bearing applications in cold environments. The production process utilizes advanced CO₂ foaming technology, which not only eliminates the use of harmful HCFCs but also creates a uniform closed-cell structure with exceptional density and consistency . This specialized manufacturing technique results in a material with a tightly controlled cell structure that balances thermal insulation properties with mechanical strength. The foam's composition includes proprietary additives that enhance both its compressive strength and low-temperature performance, ensuring that it maintains its structural integrity even in sub-zero conditions. The board's closed-cell structure, with a 99% closed cell ratio , forms a moisture barrier that prevents water absorption and ensures consistent performance in the humid conditions often encountered in cold truck applications .

Exceptional Compressive Strength

The standout feature of this product is its impressive compressive strength, ranging from 250 kPa to 1000 kPa , making it capable of withstanding heavy loads without deformation . This is particularly critical for cold truck floors, where the insulation must support the weight of cargo, pallets, and equipment during loading, transportation, and unloading. The uniform distribution of cell density throughout the board ensures consistent strength across the entire surface, eliminating weak points that could lead to premature failure. This high compressive strength allows for direct installation under cargo areas, providing both structural support and thermal insulation in a single, efficient solution.

Superior Thermal Performance in Cold Environments

Despite its focus on strength, the High Compressive XPS Foam Board delivers exceptional thermal insulation with a very low thermal conductivity of ≤0.026 W/(m·K) at -20°C . This ensures minimal heat transfer between the cold interior of the truck and the external environment, allowing the refrigeration system to maintain target temperatures more efficiently. The board's closed-cell structure prevents air circulation within the material, eliminating convection currents that could reduce insulation performance. This thermal efficiency translates directly to reduced energy consumption, longer intervals between system cycles, and extended battery life for auxiliary refrigeration units, all of which contribute to lower operational costs.

Moisture Resistance and Hygienic Properties

With a water absorption rate of less than 1% by volume , this XPS foam board offers exceptional moisture resistance, a critical property in cold truck applications where condensation is a constant challenge . The board's impermeable closed-cell structure prevents moisture penetration, ensuring that its thermal and structural properties remain unaffected even in humid conditions. This resistance to moisture also inhibits the growth of mold, mildew, and bacteria, maintaining a hygienic environment that is essential for transporting food products and pharmaceuticals. Unlike some insulation materials that can absorb odors or harbor contaminants, this XPS foam board remains clean and odor-free throughout its service life.

Dimensional Stability in Temperature Cycles

The High Compressive XPS Foam Board is engineered to maintain its dimensional stability across extreme temperature fluctuations, from sub-zero conditions inside the cold truck to high ambient temperatures during loading/unloading or in warm climates. It exhibits minimal linear expansion and contraction, tested according to ASTM D696 standards , ensuring that it remains securely in place without warping, cracking, or creating gaps that could compromise insulation performance. This stability is particularly important for maintaining the integrity of the truck's insulation envelope over time, preventing thermal bridging and ensuring consistent temperature control throughout the cargo area.

Impact Resistance and Durability

In addition to its compressive strength, this XPS foam board offers excellent impact resistance, able to withstand the bumps, vibrations, and occasional impacts encountered during transportation. This durability reduces the risk of insulation damage during cargo handling, extending the service life of the insulation system and reducing maintenance costs. The material is also resistant to degradation from common chemicals encountered in transportation, ensuring that it remains effective even with occasional exposure to cleaning agents or spilled cargo.

Here are four specific application scenarios of packaging machinery:

1、Cold storage cold chain insulation

2、Building roof insulation

3、Steel structure roof

4、Building wall insulation

5、Building ground moisturising

6、Square ground

7, Ground frost control

8, Central air-conditioning ventilation ducts

10, High-speed railway roadbed, etc.

1. Choose insulation material renowned for its superior heat preservation capabilities. Install it within the steel plating and encompass it around the vehicle's body. Suitable options include polyurethane and rigid polyurethane insulation materials.

2. While laying the insulation materials, meticulous attention must be given to prevent any gaps, ensuring optimal thermal insulation performance.

3. Secure the bonding between the insulation material and the steel plate using methods like riveting or fastening rings to reinforce the fixation of the insulation material."
