Closed Cell Waterproof XPS Foam for Refrigerated Trucks

The primary purpose of the refrigerated truck XPS foam board is to regulate air circulation and partition the vehicle into distinct temperature zones. Extruded XPS foam boards come in two types: standard and temperature-controlled. Temperature-controlled XPS foam boards are equipped with temperature control mechanisms and fans to precisely regulate the temperature within each zone.

Product Overview

As the "ideal material for chill car and heat insulation engineering" , it plays a critical role in maintaining consistent temperatures during the transportation of perishable goods, pharmaceuticals, and other temperature-sensitive products. Whether you're operating a small delivery vehicle or a large fleet of refrigerated trucks, this XPS foam solution ensures optimal temperature regulation, reduced energy consumption, and enhanced cargo protection, ultimately helping to minimize product waste and maximize operational efficiency.

Material Composition

The Closed Cell Waterproof XPS Foam for Refrigerated Trucks is manufactured using a specialized extrusion process that creates a homogeneous, high-density closed-cell structure. The core material is premium-grade extruded polystyrene, produced using eco-friendly CO₂ foaming technology that eliminates the use of ozone-depleting substances . This advanced manufacturing process results in a foam structure with a 99% closed cell ratio , which is the foundation of its exceptional waterproof and insulating properties. The material composition is carefully engineered to withstand the extreme temperature fluctuations encountered in refrigerated transport, from sub-zero cold inside the truck to high ambient temperatures outside. Unlike other insulation materials such as EPS or PU, this XPS foam is formulated to absorb up to 4 times less water , ensuring that its insulation performance remains unaffected even in humid conditions or after accidental moisture exposure.

Superior Waterproof Performance

The defining characteristic of this product is its exceptional waterproof properties, made possible by its 99% closed cell structure . This virtually eliminates water absorption, with a water seepage rate of ≤1.0% by volume even after 96 hours of immersion . This is critical in refrigerated truck applications where condensation can occur, and any moisture absorption would significantly reduce insulation efficiency. The waterproof nature of the foam also prevents the growth of mold and mildew, ensuring a hygienic environment for transporting food and pharmaceutical products. Unlike many insulation materials that degrade when exposed to moisture, this XPS foam maintains its structural integrity and thermal performance over time, even in damp conditions.

Exceptional Thermal Insulation

The Closed Cell Waterproof XPS Foam delivers outstanding thermal performance with a very low thermal conductivity of ≤0.023 W/(m·K) at -20°C , ensuring minimal heat transfer between the inside and outside of the refrigerated compartment . This high thermal resistance allows the truck's refrigeration system to maintain target temperatures more efficiently, reducing energy consumption and extending the operating time between recharges or engine running. The uniform cell structure ensures consistent insulation performance across the entire surface of the board, eliminating thermal bridges that could compromise temperature regulation. This level of thermal efficiency is particularly important for long-haul transportation where maintaining precise temperatures is critical for product integrity.

Structural Stability in Temperature Extremes

This XPS foam is engineered to maintain its structural stability across a wide range of temperatures, from the sub-zero conditions inside refrigerated compartments to the high temperatures encountered during summer transportation. It exhibits low linear thermal expansion, tested according to ASTM D696 standards , ensuring that it remains dimensionally stable even with repeated temperature cycles. This stability prevents warping, shrinking, or expansion that could create gaps in the insulation or damage the truck's interior panels. The foam's structural integrity also provides protection for the truck's interior, reducing damage from cargo movement during transportation.

Lightweight Design

Despite its impressive thermal and structural properties, the Closed Cell Waterproof XPS Foam remains lightweight, contributing to lower overall vehicle weight . This reduces fuel consumption and allows for increased payload capacity, both of which have significant economic benefits for truck operators. The lightweight nature of the foam also simplifies installation and reduces the strain on the truck's structure, extending the vehicle's service life.

Easy Installation and Custom Fit

The foam boards are designed for easy installation in various refrigerated truck configurations. They can be easily cut to size and shaped to fit around windows, doors, and other structural elements of the truck, ensuring a tight seal that minimizes heat transfer. The material's rigidity allows for secure attachment using standard adhesives and fasteners, ensuring a permanent installation that withstands the vibrations and movements encountered during transportation.

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

9, Airport runway heat insulation layer

10, High-speed railway roadbed, etc.

1. Begin by carefully selecting insulation materials renowned for their exceptional heat preservation capabilities. These materials are then positioned within the steel plate framework and meticulously enveloped around the truck's body. Common choices include polyurethane and rigid polyurethane insulation materials.

2. During the insulation material installation phase, meticulous attention is required to prevent any gaps from forming between the layers. This meticulous approach is essential to ensure optimal thermal insulation performance.

3. To secure the insulation material firmly to the steel plate, various bonding methods can be employed, such as using rivets or rings. These techniques provide additional reinforcement to uphold the insulation material in place effectively."
