EVA has excellent elasticity, flexibility, transparency, adhesion, low temperature flexibility, weather resistance, chemical resistance and compatibility with fillers and color masterbatches, and can be used for a series of foaming, blow molding, etc. processing
Depending on the use of the film, the VAc content of the EVA foam product used to prepare the film varies between 10% and 20% (mass fraction). The prepared film has the characteristics of good toughness, excellent impact resistance, high transparency, non-degradable, non-toxic and harmless and low shrinkage rate, and is widely used in the field of food packaging.
In recent years, EVA saponified or partially saponified products have been used in packaging materials, and due to its excellent gas barrier properties, the shelf life of food and other related products has been greatly improved. The product will also be widely used in flexible packaging, rigid packaging, as well as in the fields of chemicals, medicines and pesticides in the future.
EVA film is used to prepare agricultural shed film, which has good thermal insulation, high elasticity and strong resistance to environmental stress cracking. EVA can also be modified according to different application needs of agricultural film.
For example: adding an anti-drip agent to the EVA base material can effectively improve the dripping and hot-melt adhesion inhibition of the agricultural film, and obtain a fog-free agricultural film; adding a light stabilizer to the EVA base material can make anti-ultraviolet As a greenhouse agricultural film covering material, it can effectively keep warm and increase the yield of greenhouse crops; in addition, the performance of the agricultural film prepared by blending EVA and polyethylene is significantly improved, and the manufacturing cost is greatly reduced.
EVA foam material is widely used in the fields of automobile and shoemaking, but the material has the characteristics of imperviousness to puncture, slippage and hardening at low temperature. Blending and modifying EVA can significantly improve the performance of EVA products. When SBS/SIS and EVA are blended and foamed, the obtained product has excellent mechanical properties, and the comprehensive properties are obviously improved compared with traditional EVA foamed materials.
EVA resin with a VAc content of 12% to 24% can be widely used in insulation materials such as wires and cables because of its excellent fracture resistance and easy cross-linking properties, preparing heat shrinkable insulation materials, flame retardant insulation materials and semiconductor insulation The new silane cross-linked cables and halogen-free flame retardant cables prepared by EVA have achieved considerable economic benefits.
EVA foam sheet is widely used in toy manufacturing, luggage, ink and other fields, and EVA can also be used in the modification of PVC and industrial rubber products.
