Resina EVA

Hot melt adhesive is solvent-free, almost odorless, pollution-free, and easy to apply, so it is widely used in many fields. Hot melt adhesive with ethylene-vinyl acetate random copolymer (EVA) as the base resin is one of the most important varieties of hot melt adhesive, which can be used in packaging materials, book binding, wood processing and other industries.   The development of EVA hot melt adhesive in my country began in the early 1970s. In the 1980s, due to the rapid development of related industries and industries such as printing, food and beverage, wood processing, and electronics, various production lines were introduced to stimulate the rapid growth of new product development and production capacity of EVA hot melt adhesive. EVA hot melt adhesive is mainly used in the following fields in my country.   1 Book binding EVA hot melt adhesive is used for wireless binding, which changes the cumbersome processes of threading round backs, gluing, and covering the cover used in the past for binding books with latex, greatly shortening the book publishing cycle and improving work efficiency and book binding quality. 2 Wood processing In wood processing, EVA hot melt adhesive is mainly used in combination with panel furniture edge banding machines for furniture edge banding, which has changed the backward appearance of manual operation in the past, and is easy to fold and assemble, which improves labor efficiency. 3. Clothing lining EVA and EVAL powders are inexpensive and have good adhesion. They are suitable for various coating processes such as powder coating, powder dot coating, and slurry coating. The hot melt lining made of EVA hot melt adhesive can make the clothing beautiful, crisp, non-deformed, and low-cost. 4 Packaging The bonding ability of EVA hot melt adhesive is relatively stable, not affected by changes in temperature and humidity in the working environment, and eliminates the inherent gluing and peeling problems of packaging machinery. Therefore, EVA hot melt adhesive can be used in the packaging industry in the fields of cardboard and cardboard boxes, cement bags, labeling, food packaging, protective packaging, and packaging container sealing.   EVA hot melt adhesive is also used in the manufacture of electrical appliances such as televisions, air conditioners, refrigerators, as well as the shoemaking industry, PET blow molding bottles, cigarette filter winding, outer packaging tear strips, cable joint sealing, oil pipeline anti-corrosion and other fields.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com   ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

EVA resin is short for ethylene acetate-ethylene resin, which is a polymer made of ethylene acetate and ethylene monomer. According to the different contents of ethylene acetate, the copolymers of ethylene and ethylene acetate were divided into EVA resin, EVA rubber and VAE emulsion. .Products containing less than 40% vinyl acetate are EVA resins.    EVA resin has good softness and shock-absorbing properties. It is one of the materials widely used in the footwear manufacturing industry and can be used to make soles, insoles, uppers and other components. It is also often used as a cushioning material, such as knee pads, wrist pads, and ankle pads in sporting goods, as well as car seat pads, motorcycle seat pads, etc. EVA resin can be molded through various processing methods, such as extrusion, injection, calendering, etc., and it also has shock-absorbing properties. It is an excellent packaging material such as protective film, liner, protective cover, etc. to protect items during transportation and storage. No damage is caused during the process.   The chemical resistance of EVA resin can resist the erosion of many chemical substances. In medicine, EVA resin is often used to make medical instruments and equipment, such as surgical instruments, medical tapes, gloves, etc. It has good chemical resistance and transparency, and meets hygiene and health requirements. It is also an insulating material for electronic products, such as cable insulation tubes, insulating gaskets, etc. It can also be used as a protective material for batteries, with excellent chemical resistance and heat insulation properties.   In terms of building materials, EVA resin can be used as building materials, such as sound insulation panels, heat insulation panels, etc. It has good sound absorption, heat insulation and weather resistance properties, and can improve the comfort of buildings.   Agricultural use EVA resin can be used as agricultural covering film. It has good weather resistance and light transmittance, and can protect crops from bad weather.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

O filme EVA é um filme termoendurecível e pegajoso, usado principalmente no meio de vidros laminados. Possui características de alta transparência, alta aderência, boa durabilidade e fácil armazenamento.‌A alta transparência permite que a luz penetre melhor, reduzindo a perda de energia luminosa e melhorando a eficiência da conversão fotoelétrica. Alta adesão, capaz de unir firmemente diversos materiais, garantindo efetivamente a estabilidade entre os componentes. Boa durabilidade, capaz de resistir a altas temperaturas, umidade, raios ultravioleta e outros fatores ambientais, garantindo uso a longo prazo. Fácil de armazenar, pode ser armazenado em temperatura ambiente e não é afetado pela umidade e absorção de água. Baixo ponto de fusão, fácil de fluir, adequado para processos de laminação de vários vidros, como vidro estampado, vidro temperado, vidro curvo, etc. Forte efeito de isolamento acústico. Comparado com o filme PVB, o filme EVA tem um efeito de isolamento acústico mais forte, especialmente para som de alta frequência. Devido a várias propriedades excelentes, o filme EVA é amplamente utilizado em componentes atuais e vários produtos ópticos, especialmente desempenhando um papel importante na embalagem de módulos solares fotovoltaicos.Embalagem de módulo solar fotovoltaico, o filme EVA é usado para fixar células solares e fornecer proteção de isolamento, acoplamento óptico e fornece resistência mecânica moderada e caminhos de condução de calor. Nos últimos anos, com a ascensão e desenvolvimento da indústria fotovoltaica global, a demanda do mercado por EVA tem aumentado ano a ano, o que traz amplas perspectivas de mercado. Há também grande espaço para melhorias no mercado doméstico de filmes EVA. Site: www.elephchem.comWhatsapp: (+)86 13851435272E-mail: admin@elephchem.comElephChem Holding Limited, especialista profissional do mercado em Álcool Polivinílico(PVA) e Emulsão de copolímero de acetato de vinila-etileno(VAE) com forte reconhecimento e excelentes instalações fabris de padrões internacionais.
