Other EVA applications maintain a slowgrowth trend

   EVA is a halogen-free polar polymer, compatible with a variety ofmaterials, has good mechanical and physical properties, electrical propertiesand excellent mixing and extrusion process performance. EVA is the manufactureof high-voltage cable shielding material, low smoke halogen-free fuel barrierand oxygen barrier material indispensable base material, the demand is huge,there is a good prospect for development.

    With the continuous development of computerand network engineering, for the safety of the server room, people areincreasingly using halogen-free flame retardant cables and silane cross-linkedcables. As EVA resin has good filler inclusion and cross-linkability, in thehalogen-free flame retardant cables, semiconductor shielded cables and two-stepsilane cross-linked cables are used more. In addition, EVA resin is also usedin the production of some special cable sheathing. In the wire and cable usedin the foam wire and cable grade EVA resin, vinyl acetate content is generally12% to 24%.

   EVA in the use of cable wire is from medium and high voltage cable wireinside and outside the shielding material, and then extended to the fuelbarrier. These two types of material from the production and processing pointof view are regarded as "high-filled masterbatch", shielding materialdue to the need to add a lot of conductive carbon black led to a sharp increasein its viscosity, the flow of a sudden drop; fuel resistance must be added to alot of halogen-free flame retardants, but also halogen-free package ofviscosity surge, the flow of a sudden drop. The way to deal with this is tofind a polymer that can accommodate a large amount of filler, but also has alow melt viscosity and excellent flow properties, EVA has become the preferredchoice.

   Roughly estimated that the wire and cable sector EVA consumption growthrate of about 9%, higher than China's economic development rate. It is expectedthat by 2025, China's EVA consumption in the field of wire and cable is about600,000 tons, belonging to the third largest downstream consumption market ofEVA.

   In addition, in the field of adhesives, coating, agricultural film, EVAwill also play a role in the coating field, which is subject to the constraintsof low-end products, the coating field is expected to drive the consumption ofEVA growth rate of about 2%, the growth rate is relatively slow. In the fieldof agricultural film, due to the impact of substitutes, agricultural film onthe replacement of EVA will limit the application of EVA in agricultural film,as well as the rapid development of the photovoltaic industry, will also seizethe consumer market in the field of agricultural film, EVA in the field ofagricultural film is expected to show negative growth in the future consumptionscale.
