High density waterproof EVA foam block

  Among many foam materials, high-density waterproof EVA (ethylene-vinyl acetate copolymer) foam blocks are widely used in construction, packaging, transportation and other fields due to their unique properties. Today, we will take you through the material selection, manufacturing process, production process, uses and properties of this high-performance foam block.

EVA foam block

  1. High-quality material selection

  High-density waterproof EVA foam block uses high-quality EVA resin as the main raw material. This material has good water resistance, chemical resistance and excellent aging resistance. Through precise formulation and advanced production processes, we are able to ensure that the foam blocks have excellent physical properties and stable chemical properties.

  2. Exquisite production technology

  In the process of making high-density waterproof EVA foam blocks, we use advanced foaming technology and molding technology. By precisely controlling the type and amount of foaming agent and adjusting parameters such as foaming temperature and pressure, we can obtain foam blocks with uniform cell structure and excellent mechanical properties. In addition, we also use advanced surface treatment technology to make the foam blocks waterproof, moisture-proof, mildew-proof and other properties.

  3. Production process

  Ingredients: Mix EVA resin, foaming agent, additives and other raw materials evenly according to a certain proportion.

  Pre-foaming: Under a certain temperature and pressure, the EVA resin forms a uniform microporous structure.

  Molding: Put the pre-foamed EVA material into the mold and shape it by heating and pressure.

  Curing: At a certain temperature and time, the foam block is fully cured to achieve optimal performance.

  Post-processing: Cutting, grinding, surface treatment and other operations are performed on the formed foam blocks to meet the needs of different uses.

  4. Wide range of uses

  High-density waterproof EVA foam block is widely used in the following fields due to its excellent waterproof performance and good mechanical properties:

  Construction industry: used for wall insulation, floor sound insulation, roof waterproofing, etc.

  Packaging industry: used for shock-proof packaging of electronic products, precision instruments, glass products, etc.

  Transportation industry: used for cargo pallets, logistics packaging, ship sound insulation, etc.

  Other fields: It can also be used to make swimming pool floats, yacht seats, sports equipment, etc.

  5. Characteristics of high-density waterproof EVA foam blocks

  High density: Foam blocks have a dense cell structure, giving them high density and strength.

  Waterproof performance: The surface has been specially treated and has good moisture-proof, mildew-proof and waterproof properties.

  Excellent mechanical properties: high compressive strength, tensile strength and good resilience.

  Chemical corrosion resistance: It has good stability to a variety of chemical substances and is not susceptible to corrosion.

  Environmentally friendly and non-toxic: Strictly control the use of harmful substances during the production process to ensure product safety and environmental protection.

  Good processing performance: easy to cut, bend, paste and other processing operations, convenient to use.

  In short, high-density waterproof EVA foam blocks are widely used in various fields with their excellent performance. We are committed to providing you with high-quality products and professional services to meet your different needs. Let us join hands to create a better future!
