EVA (ethylene-vinyl acetate copolymer) sponge sheet, as a lightweight, soft and excellent elastic material, has been widely used in many fields. Its unique physical and chemical properties make it an ideal material for a variety of applications. This article will introduce in detail the manufacturing process and process of EVA sponge sheets, as well as products suitable for production, and conduct application analysis.
1. Manufacturing technology and process
The manufacturing process of EVA sponge sheets mainly includes steps such as raw material preparation, mixing, foaming, curing, cutting and subsequent processing.
Raw material preparation: Choose high-quality EVA resin as the main raw material, and add auxiliary materials such as foaming agent, catalyst, stabilizer, etc. as needed.
Mixing: Mix EVA resin and various auxiliary materials at appropriate temperatures to ensure uniform distribution of each component.
Foaming: The mixture is foamed in the mold through physical or chemical methods to form a sponge-like structure.
Curing: The EVA sponge sheet is further matured under controlled conditions to improve its physical properties.
Cutting: Cut the mature sponge sheets into appropriate sizes and shapes as needed.
Follow-up treatment: may include surface treatment, waterproof treatment, antibacterial treatment, etc. to meet the needs of specific applications.
2. Products suitable for production
EVA sponge sheet is suitable for making the following products because of its light weight, softness, good elasticity, water resistance, oil resistance, chemical corrosion resistance and other characteristics:
Insoles and shoe materials: EVA sponge sheets have good cushioning properties and impact resistance, and are suitable for making insoles and shoe materials to improve wearing comfort and protect foot health.
Packaging material: Its excellent buffering properties and impact resistance make it an ideal packaging material that can be used to protect fragile items during transportation.
Toys and game supplies: EVA sponge sheets are soft, safe, and non-toxic, and are suitable for making children’s toys and game supplies, such as puzzles, building blocks, etc.
Car interior: It can be used to make car seats, steering wheel covers and other interior parts to improve ride comfort and safety.
Building sound insulation materials: EVA sponge sheets have good sound insulation properties and can be used in the production of building sound insulation materials.
3. Application Analysis
