EVA hot melt adhesive to the resin as a main component, does not contain solvents, does not pollute the environment and security is high, very suitable for automated production lines, and therefore are widely used in wireless binding books, furniture Edge, cars and household appliances The assembly, footwear, carpet coatings and anti-corrosion coating on the metal. Refrigerator production conduit, gas pipes, construction lumber, container and other daily necessities, can make packaging films, gaskets, medical equipment, but also can be used as hot melt adhesives, cable insulation layer. EVA emulsions are vinyl acetate - ethylene copolymer emulsion short, it is vinyl acetate monomer and ethylene EVA products as raw materials, and other materials copolymer made of polymer emulsion by emulsion polymerization process. Copolymer of ethylene and vinyl acetate ethylene copolymer is the most important product, foreign general collectively referred to as EVA. But in our country, where people under different vinyl acetate content of the ethylene vinyl acetate copolymer resin into EVA, EVA and EVA latex rubber. Vinyl acetate content of less than 40% of the EVA resin products; vinyl acetate content of 40% to 70% of the product is very flexible; resilient characteristics, it will be this content range is sometimes referred to as EVA resin EVA rubber; vinyl acetate content of 70% - usually in the range of 95% emulsion state, it called EVA emulsion. EVA emulsion is milky white or slightly yellow appearance. Overseas Research on ethylene and vinyl acetate copolymer earlier. Imperial Chemical Company published in 1938 a high-pressure radical polymerization of EVA copolymer patents, DuPont in 1960 to achieve industrialization. From the 1960s, the country began to develop EVA resin, to the mid-1970s, a successful trial production. 1988 Beijing Organic Chemical Plant for the first time from the United States to introduce an annual 15,000 tons EVA emulsions plant, 1991 SVW again from the United States to introduce the same set of EVA latex devices. 2007 Guangxi - Dimensional Chemical Co., Ltd. from the United States introduced an annual output of 50,000 tons EVA means 2009 annual expansion of two rows of 25 000 / ton EVA device, Jiangxi Chemical Fiber Co., Ltd. set of annual self 1000 tons production line, but it has not entered a substantive production. EVA emulsion is mainly used in adhesives, coatings, cement modifiers and paper processing, it has many excellent performance. EVA emulsion having permanent flexibility. EVA emulsions can be seen as polyvinyl acetate emulsion of plasticized products, because it introduces a chain of ethylene molecules in polyvinyl acetate molecule that produces acetyl discontinuity, increasing the rotational freedom of polymer chains, steric hindrance Small, polymer main chain becomes soft, and does not occur plasticizer migration, to ensure that the product permanently soft. EVA emulsion has good acid and alkali resistance. EVA emulsion in the presence of weak acids and bases are able to maintain stable performance, whether it mixed with mild acid or alkaline breaking phenomenon will happen, a wide range of product applications. EVA emulsion resistant to UV aging. Since the use of EVA emulsion is an ethylene copolymer as an internal plasticizer, so that the polymer has a plasticizing EVA, a plasticizer does not migrate occur, thus avoiding the aging properties of the polymer. Thus, not only the EVA emulsion has good stability to ultraviolet light, that is, after the film formation EVA emulsion can also maintain this characteristic. EVA emulsion can be used as coating binders. With polyvinyl acetate emulsion, acrylic emulsion, EVA emulsion, styrene-butadiene latex, propylbenzene emulsion styrene emulsion vinegar as the base material manufactured collectively referred to as latex paint. EVA latex paint can be used as interior and exterior paint, roofing coatings, fire retardant paint, anti-rust paint. EVA latex coating blister resistance, anti-aging and difficult to crack, and a variety of substrates have good adhesion, safe non-toxic, and easy to use. EVA latex paint can be applied not only on wood, masonry and concrete, but also applied to metal, glass, paper, fabric surface, it is also very good affinity with paint, you can brush each other on the surface. http://mayu1991619.jdzj.com/ http://mayu1991619.b2b.youboy.com/ http://m1991619.cn.china.cn/ http://mayu1991619.955101.com/ http: // mayu1991619. cn.gongchang.com/ http://www.datoumao.com/gongsi/mayu1991619/ http://www.kejiqi.org/corp/mayu1991619/ http://mayu1991619.8j8.cc/ http: // mayu1991619. cn.b2b168.com// http://www.sooshong.com http://www.cntrades.com/b2b/mayu19911619
