The thermal insulation principle of aluminum foil heat insulation reflective foil is to reflect light, so it has a certain thermal insulation effect. If you want to have a good insulation effect, it is recommended to use professional thermal insulation composite materials (such as phenolic board, rock wool, EPS and XPS, etc.) to choose suitable materials according to different needs. Aluminum foil can be used for thermal insulation in high temperature environment. It is mainly to block high temperature heat radiation. Using the characteristics of high reflectivity of aluminum foil surface, multi-layer aluminum surface reflection can achieve the purpose of completely blocking heat radiation. However, through the air between the aluminum surfaces, there will still has a small amount of convective heat transfer. If complete heat insulation is required, a multi-layer aluminum foil reflective insulation structure can be used.
Common reflective insulation materials are mainly aluminum foil or aluminized film, which is compounded with air bubbles, foam, woven fabrics, non-woven fabrics, etc. The aluminum foil used for aluminum foil heat insulation reflective foil is 8011 aluminum foil insulation, and it is usually used as composite structure in heat insulation application. The reflective heat insulation material and can be roughly divided into two categories: air bubble insulation materials and foam insulation materials; air bubbles film overcomes the shortcomings of ordinary styrofoam, which are fragile, deformed, and poor in recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.
Aluminum foil heat insulation reflective foil is widely used in automobile sunshade light blocking cushion, electronic appliances, instrumentation, computer, audio, equipment, industrial control chassis, hardware lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture furniture, wine and resin, etc. Gift packaging, hardware products, toys, inner packaging, daily necessities and other products packaging. After adding color antistatic agent and flame retardant, its performance is even more obvious. Not only is the appearance beautiful, but also the adhesive products that prevent static electricity and ignition and various fabrics are good interior decoration materials for various vehicles and rooms. The composite product of EPE pearl cotton and aluminum foil or aluminized film has excellent anti-infrared ultraviolet ability, and is a necessary product for some chemical equipment refrigerators and camping equipment automobile sunshade. Its pipes are widely used in air conditioners, baby carriages, children’s toys, furniture, plumbing and ventilation and other industries.
