Polyester
Polyester is a polymer material with excellent physical properties and chemical stability, commonly used in the production of insulation films for thermal bags. Compared to other materials, polyester has advantages such as heat resistance, corrosion resistance, and low cost, but its thermal insulation performance is relatively poor. Therefore, it is suitable for short-term insulation.
Foamed Plastics
Foamed plastics are an important insulation material. They are lightweight, have extremely low thermal conductivity, and provide excellent thermal insulation. The advantages of foamed plastics are their light density, low cost, and good waterproof and shockproof performance, but they are not resistant to high temperatures and are prone to aging.
Aluminum Foil
Aluminum foil is a highly efficient insulation material with better insulation performance than other materials. It has advantages such as light weight, good water resistance, and corrosion resistance. However, aluminum foil has disadvantages such as being easily damaged and easily contaminated, so careful selection is necessary.
Glass Wool
Glass wool is an environmentally friendly, energy-saving, and high-performance insulation material. Its advantages include excellent thermal insulation performance, ease of construction, and good water resistance. However, it also has disadvantages such as being hygroscopic, flammable, and difficult to construct.
