Chemical Structure
-
Stability: good chemical stability, aging resistance and ozone resistance.
Water resistance: closed cell structure, non-absorbent, moisture-proof, and good water resistance.
Corrosion resistance: Resistant to corrosion by seawater, grease, acid, alkali and other chemicals, antibacterial, non-toxic, odorless and pollution-free.
Processability: No joints, and easy to process such as hot pressing, cutting, gluing, and lamination.
Anti-vibration: High resilience and tensile strength, high toughness, and good shock-proof and buffering properties.
Thermal Insulation: Excellent in heat insulation, cold protection and low temperature performance, and can withstand severe cold and exposure to the sun.
Sound insulation: closed cells, good sound insulation effect.
EVA resin is widely used in various industries and can be used as crude oil wax inhibitor and flow point improver; widely used in various footwear and sound insulation boards; produces a variety of packaging films, medical films, casting films; makes toys, Halogen-free flame retardant cables and silane cross-linked cables; main components of EVA glue, etc.
Hot melt adhesive with EVA resin as the main component does not contain solvents, does not pollute the environment and is highly safe, making it very suitable for automated assembly line production.
