There are a variety of EVA boxes on the market, which have a wide range of use in our lives, then what kind of features does the eva box have?
1, thickness: not less than 0.5mm, not more than 60mm (the whole board), the error range of ± 0.2mm.
2, the general specifications of the sheet: 1000 * 2000 * 0.5-60mm, 1000 * 3000 * 0.5-60mm, 1500 * 3000 * 0.5-60mm, 1200 * 2500 * 0.5-60mm, the EVA has different materials or hardness.
3, color: usually black and white, color can be customized according to customer requirements.
4, hardness: usually 38P-50P, a special degree of hardness 60P-70P, high elastic 20P-38P, error range: ± 3-5P.
5, the role of performance: water, decay, shock, heat, noise and so on.
A, water resistance: closed cell structure, non-absorbent, moisture-proof, water resistance is good.
B, corrosion resistance: resistance to sea water, grease, acids, alkalis and other chemicals corrosion, antibacterial, non-toxic, tasteless, non-polluting.
C, processability: and easy to hot pressing, tailoring, glue, paste and other processing.
D, anti-vibration: high resilience and tensile strength, toughness, with good shock / buffer performance.
E, thermal insulation: heat insulation, excellent warm-keeping performance, resistance to cold and exposure.
F, Sound insulation: closed cell, good sound insulation.
6, testing through EN71 Part 1-3 and AHR4040 \ ASTMF96 \ formamide.
