Ethylene vinyl acetate copolymer physical and chemical properties, the main features, functional uses and safety precautions and other information for your reference. EVA Physical and chemical properties, basic information: Chemical Chinese name: Ethylene - vinyl acetate copolymer Stability: Has good chemical stability, anti-aging, ozone resistance. Explosion hazard: This product is composite fence jamb manufacturers flammable, irritating. Skin contact: Remove contaminated clothing, rinse with running water. Eye contact: Lift the eyelids, rinse with running water or saline. Get medical attention. Inhalation: Remove from the scene to fresh air. Get medical attention. Ingestion: drink enough warm water, induce vomiting. Get medical attention. Eva performance, features: Water resistance: closed cell structure, non-absorbent, moisture-proof, water resistance is good.
Corrosion resistance: resistance to sea water, grease, acids, alkalis and other chemicals corrosion, antibacterial, non-toxic, tasteless, non-polluting. Machinability: No joints, and easy to hot pressing, tailoring, glue, paste patio wood plastic fence trinidad and other processing. Anti-vibration: high resilience and tensile strength, high toughness, with good shock, cushioning performance. Insulation: heat insulation, cold insulation and excellent low temperature performance, resistance to cold and exposure.
Sound insulation: closed cell, good sound insulation. EVA Uses: Under normal circumstances, the content of vinyl acetate less than 5% of EVA, its main products are film, wire and cable, LDPE modifiers, adhesives, etc .; vinyl acetate content of 5% to 10% of EVA products For the elastic film; vinyl acetate content of 20% to 28% of the EVA, mainly for hot melt adhesives and coating products; vinyl acetate content of 5% to 45%, the main products for the film (including agricultural film) And sheet, injection laminate wood flooring molding, molded products, foam products, hot melt adhesives.
China is a large agricultural country, and EVA plastic film or EVA multi-layer composite film has great advantages in cold resistance, anti-aging, anti-mist drip properties, so one of the greatest needs of EVA in the next few years will be agricultural film, foreign At present, functional films are made of 100% EVA material, and only 20-40% of functional films in China use EVA material. Therefore, EVA should be expanded in the field of development and application, and the best wood plastic composite manufacturers in china market share will increase.
