EVA V6110S

EVA hot melt adhesive is a solvent-free, water-free, 100% solid fusible polymer. It is solid at room temperature and becomes a liquid adhesive that can flow and has a certain viscosity when heated and melted to a certain degree. It is light brown translucent or white after melting.   EVA(EVA V6110S) hot melt adhesive is mainly made of the following four components: base resin, namely EVA resin, tackifying resin, wax, antioxidant, and a small amount of filler can be added in some occasions to increase the gap filling and reduce costs.   EVA hot melt adhesive has the following characteristics: (1). It has fast curing, low pollution, strong adhesion, and the adhesive layer has certain flexibility, hardness, and toughness; (2). After the adhesive liquid is applied to the adherend and cooled and solidified, the adhesive layer can be heated and melted again to become an adhesive body and then bonded to the adherend, with a certain degree of re-adhesion; (3). When using, just heat and melt the hot melt adhesive into the required liquid state and apply it to the adherend. After pressing, the bonding and curing can be completed within a few seconds, and the hardening, cooling and drying can be achieved within a few minutes.   The type of EVA determines the cohesive strength, flexibility, adhesion to the substrate and processability of the hot melt adhesive. For hot melt adhesive, the following properties of EVA should be paid attention to: molecular weight and its distribution, vinyl acetate (VA) content, crystallinity, softening point, melting point, melt index (MI) and melt viscosity, etc., because these properties directly affect the various properties of hot melt adhesive.   As the melt index of EVA increases, its strength, hardness, softening point and viscosity all decrease regularly; and the more VA content in EVA, the greater the elongation at break and the lower the hardness. In addition, when the VA content exceeds 30%, although the adhesion to polar and various non-porous non-polar substrates is improved, this EVA polymer is incompatible with wax, which is a point to be noted when designing hot melt adhesive formulas. In a formula, it is often necessary to use EVA with different MI or EVA with different VA content to obtain satisfactory comprehensive performance.   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( Ethylene Vinyl Acetate) 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.

Ethylene Vinyl Acetate (EVA) film is a thermosetting and sticky film, mainly used in the middle of laminated glass. It has the characteristics of high transparency, high adhesion, good durability and easy storage. ‌ ‌High transparency allows light to penetrate better, reducing light energy loss and improving photoelectric conversion efficiency.   ‌High adhesion, able to firmly bond various materials, effectively ensuring the stability between components.   ‌Good durability, able to resist high temperature, moisture, ultraviolet rays and other environmental factors, ensuring long-term use.   ‌Easy to store, it can be stored at room temperature and is not affected by humidity and water absorption.   ‌Low melting point, easy to flow, suitable for lamination process of various glass, such as patterned glass, tempered glass, curved glass, etc.   Strong sound insulation effect. Compared with PVB film, EVA film has stronger sound insulation effect, especially for high-frequency sound.   Due to various excellent properties, EVA film is widely used in current components and various optical products, especially playing an important role in the packaging of solar photovoltaic modules.‌Solar photovoltaic module packaging, EVA film is used to fix solar cells and provide insulation protection, optical coupling, and provide moderate mechanical strength and heat conduction paths.   In recent years, with the rise and development of the global photovoltaic industry, the market demand for EVA(V6110S) has increased year by year, which has broad market prospects. There is also great room for improvement in the domestic EVA film market.   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.
