As a leading manufacturer, Whole Chain Tech defines its PU core dry truck body as a lightweight composite solution engineered with high-density closed-cell foam; this structure delivers superior insulation, moisture resistance, and structural rigidity, while its low-water-absorption property effectively reduces the risks of thermal degradation and corrosion common in traditional cores, making it ideal for high-efficiency logistics and demanding transport environments.
● Core Material: High-density PU foam, integrally foamed for stable thermal insulation performance.
● Panel Options: FRP or aluminum panels, offering a smooth surface and excellent weather resistance.
● Structure: Sandwich composite panel construction, delivering lightweight design, high strength, and superior deformation resistance.
● Frame: Constructed with aluminum or steel frames for enhanced rigidity and durability.
● Thermal Insulation: Maintains an R-value of R-12 to R-20, ensuring stable heat insulation.
● Weight Reduction: 5–10% lighter than traditional boxes, reducing fuel consumption and improving transport efficiency.
● Strength: Meets the requirements of general cargo transport, urban distribution, and light modification needs.
● Durability: Resists impact and aging, with easy maintenance for long-term use.
● Lightweight: Reduces fuel consumption and boosts transport efficiency.
● Cost-Effective: Lower cost than all-aluminum boxes, offering better overall value.
● Stable Insulation: Protects cargo conditions for non-refrigerated short-haul transport.
● Versatility: Compatible with mainstream North American chassis, facilitating easy installation for conversion workshops.
● Fast Delivery: Mature production process ensures short lead times and quick delivery
| Comparison Dimension | PU Core (Polyurethane) | Honeycomb Core | Our Product Recommendation |
| Structure Type | closed-cell foaming | Honeycomb hollow structure | Both are applicable, depending on specific usage needs |
| Weight | Medium, relatively high density | Lightweight, lighter at the same thickness | Choose honeycomb core for lightweight demand (e.g., long-distance general cargo transport); choose PU core for no strict weight requirement |
| Strength & Rigidity | General strength, medium rigidity | High strength, good rigidity and strong impact resistance | Prioritize honeycomb core for heavy-duty cargo, special transport or outdoor scenarios; PU core is sufficient for regular light and medium cargo |
| Thermal Insulation Performance | Excellent | General | PU core is recommended if there is a basic thermal insulation need; honeycomb core is optional for normal dry cargo without insulation demand |
| Waterproof & Moisture-proof | Good | Genral | PU core is preferred for areas with high humidity or frequent rain; honeycomb core can be used for dry environments |
| Sound Insulation Performance | Good | General | depending on specific usage needs |
| Flatness & Surface Quality | Good | Good , but edges need treatment | Both are applicable; PU core is more convenient for surface modification |
| Processing & Molding | Integral molding | Composite molding processing | PU core is recommended for customized-shaped dry van bodies; honeycomb core is suitable for standard-sized, high-strength demand bodies |
| Cost | Medium cost, high cost-performance ratio | High cost, high expense for face sheet + honeycomb structure | PU core is recommended for cost-sensitive customers ; honeycomb core is suitable for high-end, high-demand |
| Service Life | Long service life, aging-resistant | Long service life, but honeycomb edges are prone to corrosion/moisture damage | Both have long service life; honeycomb core requires regular edge maintenance, while PU core is more maintenance-free |
