The benefits of producing aluminum-plastic panels using PE supercritical carbon dioxide foaming:; Replacing chemical foaming agents with CO ₂ to achieve green manufacturing, while obtaining a more uniform microporous structure, better sound insulation, thermal insulation, and mechanical properties;.
Environmental Protection‌ No combustible or explosive gases such as butane are used, no VOCs emissions are generated, and the product meets environmental requirements and can be recycled and reused.
Performance: Uniform cell size (usually); 50-200μm）、 High closed cell rate, and superior impact toughness, sound insulation, and thermal insulation performance compared to traditional chemical foam products;.
Craftsmanship‌ By controlling the foaming ratio and cell structure through gas flow rate, pressure/temperature, the product size is stable, there are no surface shrinkage marks, and customization is flexible;.
Cost‌ The cost of foaming agent (CO ₂) is relatively low and recyclable, with controllable energy consumption for long-term operation.
Key differences compared to traditional chemical foaming;
Foaming agent Supercritical CO ₂ (physical change, environmentally friendly and recyclable) vs chemical powder/gas (decomposition produces by-products, difficult to recycle).
Microstructure Fine and uniform closed pores are prone to bubbles of varying sizes or collapse.
Final performance High specific strength, low thermal conductivity, no odor; vs There may be residual odors and significant performance fluctuations;.
This technology is particularly suitable for aluminum-plastic composite panel scenarios that have high requirements for environmental certification, lightweight, and functionality (such as building decoration and sound insulation, traffic weight reduction and lightweight).
PE aluminum-plastic composite panel (also known as PE aluminum-plastic board) is a new type of decorative material that is favored by people for its economy, diversity of colors, convenient construction, excellent processing performance, fire resistance, and high quality.
Characteristics: rich decorative features, weather resistance, corrosion resistance, impact resistance, fire resistance, moisture resistance, sound insulation, heat insulation, seismic resistance; lightweight, easy to process and shape, easy to handle and install, etc.
Application areas: It can be applied in architectural decoration, such as ceilings, column cladding, counters, furniture, telephone booths, elevators, storefronts, billboards, and factory wall materials. It has become a representative of metal curtain walls among the three major types of curtain walls (natural stone, glass curtain walls, and metal curtain walls). Aluminum-plastic panels can also be used in the manufacturing of high-speed rail, yachts, buses, train compartments, soundproof materials for aircraft and ships, instrument cases, and more
Nowadays, it is widely used in the market for mobile homes, prefabricated houses, building facades, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, etc. It is a new type of architectural decoration material.
