Analysis on the advantages and advantages of eva foam cotton

Eva foam cotton is a new type of environmentally friendly foaming material. Eva foam cotton is generally exquisitely made, and has the advantages of excellent cushioning, anti-vibration, heat preservation, moisture resistance, chemical corrosion resistance, etc., and is non-toxic and non-absorbent, and the surface is soft. The tensile strength is stronger than that of LDPE, but the surface is sticky and has no glue. The molding and in-mold foam molding technology has the advantages of industrial continuity, short production cycle and saving required materials. EVA has a wide range of applications in our daily production and life, including: anti-static EVA, high-elastic EVA, odorless EVA and other foam aspects, but it is even more puzzling for our daily life professionals who are not professionals in this area. Eva foam cotton has rubber-like elasticity, is very soft and tough, can still have good flexibility at minus 50 ° C, good transparency and surface gloss, excellent chemical stability, anti-aging and ozone resistance Good strength, non-toxic. Good blending with fillers, good coloring and molding processability. Eva foam cotton can be used repeatedly and has relatively little harm to the environment. With the social development of social forms, the social development of people’s environmental awareness and the use of eva foam in the packaging industry is very important. One factor that should be paid special attention to during EVA low-foam extrusion molding is that the melt should flow smoothly through the cavity to form a smooth surface that is less likely to crack it. The lubricant affects the surface finish of the cavity, the mixing and distribution of the foaming gas, and thus affects the cells of the EVA foam.

1. The anti-vibration and buffering properties are excellent. To measure the quality of a required material, it should start from its anti-vibration, because the factory products have to go through the links of storage, logistics transportation, and cargo handling after being packaged. In these links, the factory products are extremely vulnerable to the impact of external forces and cause damage to the factory products! Eva foam cotton is a kind of material required for high elasticity, with excellent cushioning and anti-vibration performance, which can ensure that the factory products are in good condition.

2. Very low water absorption: low density and excellent floating performance.

3. Environmental protection acceptance materials, many of the previous outer packaging factory products have environmental protection problems, which are easy to cause environmental protection problems to the environment. The eva foam is a new type of material required for environmental protection. It has the characteristics of biodegradation to ensure that it will not cause environmental problems to the environment.

4. The eva foam cotton is not easily deformed, cut flat, and environmentally friendly for long-term use. It is used for insulation, buffering, sealing, heat preservation, anti-vibration, dust-proof, fire-proof, anti-static, filling, fixing and beautification of outer packaging products. and so on.

5, eva foam cotton is widely used in electrical appliances, precision instruments, instruments, office equipment, sporting goods, hardware and electrical machinery, automotive electronic accessories, air conditioning and refrigeration accessories, cold storage insulation materials, machinery and equipment sealing buffers, various precision instruments, medical knives , measuring tools, tableware, packaging lining of jewelry gift boxes and other products such as vibration-proof buffering outer packaging and other fields.

6. Low temperature resistance: The physical properties will not change under the conditions of -170 ℃ to 105 ℃, which is very suitable for the refrigeration and air-conditioning industry as the material required for thermal insulation.

7. Flame retardancy: PEF and EVA have flame retardancy after formula adjustment.

8. Anti-corrosion: no corrosive effect on metal equipment.

9. No pollution: This product is non-toxic, tasteless, mildew, moth-eaten, and rotten.

10. Good-looking appearance: smooth and smooth, colorful and diverse.

11. Convenient construction: The required materials are easy to process, and can be cut arbitrarily. When fitting the equipment for maintenance, the materials required for heat preservation can be reused to reduce the cost of heat preservation.

12. Water resistance: closed cell structure, non-absorbent, moisture-proof and water-resistant.

13. Corrosion resistance: It is resistant to corrosion by chemicals such as seawater, grease, acid, and alkali, and is antibacterial, non-toxic, odorless, and non-polluting.

14. Processability: There are no joints, and it is easy to process such as hot pressing, cutting, gluing, and lamination.

15. Anti-vibration: high resilience and tensile strength, high toughness, excellent anti-vibration and cushioning performance.

16. Thermal insulation: thermal insulation, thermal insulation and cold protection and low temperature performance are excellent, and it can withstand severe cold and exposure.
