Eva material is an extremely common material, which is a common kind of midsole material in daily life. The finished products made from it have good softness, shock resistance, skid resistance and strong pressure resistance, such as our common EVA slippers, cotton shoes, EVA mobile phone protective cases, EVA ipad protective cases and so on.
Polymerization method with high pressure bulk polymerization (plastic), solution polymerization (PVC processing AIDS), emulsion polymerization (binder), suspension polymerization. The content of vinyl acetate (VA) is higher than 30% by emulsion polymerization, low content of vinyl acetate by high-pressure bulk polymerization.
EVA soles are shoes made of EVA material. High toughness, EVA sole resilience and resistance to tension, has a good shockproof, buffer performance, heat insulation, insulation cold and low temperature resistance, resistant to cold and exposure, airtight bubble hole, sound insulation effect is good, airtight bubble pore structure, non-absorbent, moisture-proof, good water resistance, resistance to sea water, oil, acid, alkali and other chemical corrosion, antibacterial, non-toxic, tasteless, no pollution.
Use 1: eva materials can be used to make household refrigerator conduits, gas pipes, civil construction boards, containers and other household articles and daily necessities.
Purpose 2: eva material can be used for packaging film, gasket, medical equipment, can also be used as hot melt adhesive, cable insulation layer, etc.
Purpose 3: eva materials are widely used in wireless bookbinding, digital product shell structure, furniture edge sealing, automobile and household appliances assembly, shoe making, carpet coating and metal anticorrosive coating.
Disadvantages:
Poor heat resistance.
Compared with LDPE, its barrier performance is reduced.
Intolerant to polar solutions, hydrocarbons, oxidants and strong acids.
Compared with LDPE, its creep resistance is reduced.
