EVA material production process

    Moyuan foam produces and supplies EVA materials, which can be used to produce rolls or sheets, such as punching, which can be used as packaging linings, and hot pressing can be used to make shoe soles. EVA materials can be used in packaging linings, electronics, hardware, and toy industries. Ethylene-vinyl acetate copolymer (EVA) is the main raw material, PE polyethylene raw material is added as auxiliary raw material, AC foaming agent, color masterbatch, stabilizer and other auxiliary materials are added, and the weight is lighter by heating and foaming through a 180 degree steam mold. : The density of EVA ranges from 0.91 to 0.93, and the specific gravity of the secondary foaming will be lower, ranging from 25 kg to 50 kg per cubic meter. No odor: EVA does not contain ammonia or other organic odors .

    Free of heavy metals: Comply with the relevant international toy regulations (EN-71 Part 3 and ASTM-F963).

    No phthalates: suitable for children's toys and will not cause the risk of plasticizer release.

    High transparency, softness and toughness: the application range is very wide.

    Super low temperature resistance (-70C): suitable for freezing environment.

    Resistant to water, salt and other substances: it can maintain stability in large amounts of application.

    High heat adhesion: It can be firmly attached to nylon, polyester, canvas and other plastics.

    Can be screen printed and offset printing: can be used for more fancy products (but must use EVA ink).

    Water resistance: airtight cell structure, no water absorption, moisture resistance, good water resistance. Corrosion resistance: resistant to sea water, grease, acid, alkali and other chemicals, and non-toxic. Processability: No joints, and easy to process such as hot pressing, cutting, gluing, and bonding. Anti-vibration: high resilience and anti-tension, high toughness, good shock-proof and cushioning performance. Thermal insulation: excellent thermal insulation, cold-preservation and low-temperature performance, and can withstand severe cold and exposure. Sound insulation: airtight cell, good sound insulation effect.

    The difference between coarse hole EVA and ordinary EVA

    The rubber and plastic foaming industry has a history of more than ten years in China. With the development of science and technology and the continuous updating of technology, China's foaming industry has made great progress, but there are still many materials that are difficult to match with foreign materials. compared to. The consumption of EVA in China is very large, and it is used in many industries. The demand side does not know that the EVA material is used, or even the purpose of EVA. However, professional manufacturers do not know how many industries use this material. Everyone knows that domestic things are cheap and affordable, but many times they don’t pay attention to quality. Whether it is a domestic user or a foreign user, the products purchased are of course good quality at a low price. Domestic users are okay. In many cases, as long as they can be used, the price is acceptable, but foreign users are not like this. They pay more attention to quality and environmental protection. After a long period of application of EVA industry in China, the technology of EVA foaming is no longer so conservative. Many manufacturers are able to produce. The competition is becoming more and more fierce. This has caused many manufacturers to lower their prices and further form the profitability of the EVA industry. The smaller, the formation of a vicious circle. Since foreign customers pay attention to quality, what kind of materials do foreign customers require? Of course, it is a material with good quality, many advantages, and an affordable price. Many people do not understand coarse-pored EVA materials. Coarse-pored EVA is a new alternative to ordinary closed-cell EVA. It not only inherits the advantages of ordinary closed-cell EVA positioning, cushioning, and environmental protection, but also inherits the advantages of sponge opening and moisture absorption, and also has anti-rust, tear-resistant, The advantages of scratch resistance and sound insulation. It is an excellent material work. Since coarse-hole EVA products have so many advantages, they are widely used in industries, mainly in: shoe materials, packaging, rust-proof packaging, positioning packaging, environmentally friendly packaging, cushioning packaging, instrument lining, auto parts lining, All kinds of precision instruments, meters, tools, measuring tools, anti-rust packaging, all kinds of engineering anti-rust, tasteless, modern sound-absorbing materials such as automobiles, trains, airplanes, submarines, etc.
