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.

La película EVA es una película termoestable y pegajosa, que se utiliza principalmente en medio de vidrio laminado. Tiene las características de alta transparencia, alta adherencia, buena durabilidad y fácil almacenamiento.‌La alta transparencia permite que la luz penetre mejor, lo que reduce la pérdida de energía luminosa y mejora la eficiencia de la conversión fotoeléctrica. Alta adherencia, capaz de unir firmemente varios materiales, asegurando eficazmente la estabilidad entre los componentes. Buena durabilidad, capaz de resistir altas temperaturas, humedad, rayos ultravioleta y otros factores ambientales, lo que garantiza un uso prolongado. Fácil de almacenar, se puede almacenar a temperatura ambiente y no se ve afectado por la humedad ni la absorción de agua. Bajo punto de fusión, fácil de fluir, adecuado para procesos de laminación de varios tipos de vidrio, como vidrio estampado, vidrio templado, vidrio curvo, etc. Fuerte efecto de aislamiento acústico. En comparación con la película PVB, la película EVA tiene un efecto de aislamiento acústico más fuerte, especialmente para sonidos de alta frecuencia. Debido a sus excelentes propiedades, la película EVA se usa ampliamente en componentes actuales y diversos productos ópticos, especialmente desempeñando un papel importante en el empaque de módulos solares fotovoltaicos.Embalaje de módulos solares fotovoltaicos, la película EVA se usa para fijar células solares y proporcionar protección de aislamiento. Acoplamiento óptico y proporciona resistencia mecánica moderada y rutas de conducción de calor. En los últimos años, con el auge y desarrollo de la industria fotovoltaica mundial, la demanda del mercado de EVA ha aumentado año tras año, lo que tiene amplias perspectivas de mercado. También hay un gran margen de mejora en el mercado nacional de películas EVA. Sitio web: www.elephchem.comWhatsapp: (+)86 13851435272Correo electrónico: admin@elephchem.comElephChem Holding Limited, profesional experto en el mercado en Alcohol polivinílico(PVA) y Emulsión de copolímero de acetato de vinilo y etileno(VAE) con fuerte reconocimiento y excelentes instalaciones de planta de estándares internacionales.
