Thermal insulation foam is a material with excellent thermal insulation properties, primarily made from polymer materials such as polyethylene (PE) through a foaming process. This type of material contains a large number of closed micro-pores, which effectively prevent heat conduction, thereby achieving thermal insulation effects. Depending on different usage scenarios and requirements, thermal insulation foam can be processed into various shapes and thicknesses. Thermal insulation foam have the following features：
- Lightweight: Due to its internal structure being primarily air, the overall weight is very light.
- Good thermal insulation: The large number of closed bubbles inside can effectively block heat transfer.
- Waterproof and moisture-proof: The closed cell structure makes it difficult for moisture to penetrate.
- Strong corrosion resistance: It shows good resistance to most acid and alkali solutions.
- Good sound insulation: Benefiting from its unique structural design, it can also provide a certain degree of sound absorption.
- Easy to process and install: It can be cut to any size as needed, and the smooth surface facilitates adhesion or fixation.
- Environmentally friendly and safe: Many types of thermal insulation foam do not contain CFCs, making them environmentally friendly.
