Foam, this seemingly simple material, actually hides rich science and technology behind it. Foam can be classified into various types based on different dimensions such as raw materials, production processes, and functionality. Understanding the classification of foam can help us make better choices and applications. So, please follow me into the world of foam and explore its diverse charm.

1. Classified by raw materials:

-Polyethylene foam (PE): Low density, high strength, suitable for electronic packaging, automotive interior and other fields.

-Ethylene acetate foam (EVA): Good cushioning and weather resistance, commonly used in sports insoles, toys, etc.

-Chloroprene rubber foam (CR): fire-resistant and chemically resistant, used in diving suits, automotive parts, etc.

-Natural latex foam: soft and comfortable, mainly used for household items such as mattresses and pillows.

2. Classified by opening type:

-Closed cell foam: The cell structure is closed, with good waterproof and insulating properties, such as EVA foam.

-Open cell foam: The cell structure is open and has good breathability and sound absorption, such as natural latex foam.

3. Classified by functionality:

-Shockproof foam: With excellent cushioning performance, it is widely used in electronic product packaging, sports equipment, etc.

-Thermal insulation foam: It has insulation properties and is commonly used as an insulation layer for household appliances such as refrigerators and air conditioners.

-Acoustic foam: It can reduce noise and is used in places that require sound insulation such as recording studios and home theaters.

-Conductive foam: It has anti-static function and is mainly used for packaging and storage of electronic products.
