Marble-patterned PU sandwich wall panels provide highly efficient insulation
Production Description
Our company's PU sandwich wall panels adopt a dual-core process of high-pressure injection and constant-temperature curing. We carefully select high-density polyurethane raw materials and combine them with environmentally friendly flame-retardant additives. After precise dosage and mixing, they are injected into molds under high pressure and solidified in a constant-temperature environment of 120℃. We strictly control the density of the core material and the closed-cell rate to ensure that they are lightweight (only 1/3 of traditional wall panels) and resistant to pressure and deformation.
Subsequently, through an automated composite production line, the PU core material is closely bonded with the glass fiber reinforced panel. Then, the texture of natural stone is replicated by 3D embossing technology, and a waterproof and UV-resistant coating is sprayed on the surface. The entire process is equipped with six quality inspection checkpoints, with strict control from raw materials to finished products. The final products are precisely sized, structurally solid, and feature heat insulation, sound insulation, and easy installation, meeting international environmental protection standards for building materials.

Differentiation advantage
| Comparison Aspects | Our PU Sandwich Panels | Industry Competitors' Products |
|---|---|---|
| Core Material Formula | Imported high-density PU foam core, closed-cell rate ≥95%, stable thermal insulation and soundproofing performance | Ordinary low-density PU core, low closed-cell rate, prone to moisture absorption and shrinkage |
| Production Process | Full-automatic continuous foaming + double-sided color steel lamination technology, firm adhesion without delamination | Manual intermittent foaming, uneven lamination pressure, prone to hollowing |
| Core Performance | Fire resistance up to Class B1, thermal conductivity ≤0.022W/(m·K), strong wind pressure resistance | Most fire resistance at Class B2, higher thermal conductivity, prone to deformation after long-term use |
| Specification Customization | Supports customization of thickness (50-200mm) and width (1000-1200mm) to meet special project needs | Single specifications, only supports conventional sizes, poor adaptability |
| Export Services | Provide EN 13501-1 and ISO 14001 certifications, one-stop service for sea freight bundling & customs clearance documents | Incomplete certifications, customers need to prepare customs declaration materials independently, no professional bundling solutions |
Application scenarios
Our PU sandwich panels, with their core advantages of heat insulation, sound insulation, fire resistance and light weight, are widely adapted to the needs of various building scenarios. It can be used in the industrial field for the walls and roofs of factory workshops and warehouses. It has strong wind pressure resistance and weather resistance, can reduce energy consumption and is suitable for large-scale rapid construction. In commercial Spaces, it is applicable to the partition walls of shopping malls, the ceilings of office buildings, and the insulation layers of hotels. Its B1-level fire resistance performance and low thermal conductivity meet the safety and energy-saving standards.
In terms of civil buildings, it can be used as exterior wall insulation boards for residences and enclosure materials for prefabricated houses. Its lightweight feature reduces the load on buildings, and it is easy and efficient to install. In the field of cold chain logistics, it is used as the insulation layer for cold storage and refrigerated truck bodies. Its closed-cell structure locks in temperature, facilitating constant-temperature storage. In addition, scenarios such as temporary exhibition halls, construction site dormitories, and clean rooms can also rely on their customized specifications and environmental protection attributes to achieve rapid assembly and long-term stable use.
