EVA hot melt adhesive, whose main component is ethylene-vinyl acetate copolymer, is a polymer formed by the high-pressure copolymerization reaction of ethylene and vinyl acetate. At room temperature, it appears in a solid state, quiet and calm; once heated, it will quickly melt into a flowing and highly viscous liquid, just like an awakened elf, showing powerful bonding magic.
Its molten state is usually a light brown translucent body or an off-white color, pure and mysterious. This hot melt adhesive also adds tackifiers, which is like installing a powerful engine for its bonding ability, enabling it to embrace the adherend more closely; the addition of viscosity modifiers makes it flow more smoothly and cover the material surface evenly; antioxidants are like guardian angels, preventing the colloid from oxidizing and deteriorating at high temperatures and ensuring the stability and durability of its performance.
The biggest feature of EVA hot melt adhesive is its excellent flexibility. It is like a flexible dancer who can easily adapt to objects of various shapes and will not break easily when bent or folded, providing a reliable guarantee for bonding.
Moreover, it has strong adhesion to a variety of materials, whether it is paper, cloth, plastic or wood, it can be closely combined with them, and its versatility is extremely strong.
In the clothing field, EVA hot melt adhesive has made great contributions. When making clothing labels, those small labels need to be firmly attached to the clothes, and EVA hot melt adhesive can accurately exert its force. It can fix the labels stably and not easy to fall off after experiencing daily tests such as washing and friction. It is also often used in the lining cloth fitting of shirt collars and cuffs, making the clothes more crisp and comfortable to wear.
The shoemaking industry is even more inseparable from EVA hot melt adhesive. In the composite process of the upper and the sole, it can closely connect different materials like a bridge. Whether it is a leather or fabric upper and a rubber or plastic sole, it can be seamlessly bonded by it, ensuring the firmness of the shoes during walking and sports and making our every step firm and powerful. It also performs well in the bonding of insoles. It not only bonds firmly but also can withstand washing, keeping the insoles in place for a long time and providing continuous comfortable support for the feet.
In the packaging industry, EVA hot melt adhesive shows its great ability even more. The sealing of cartons is its specialty. On the high-speed automatic production line, it can quickly melt and smear, firmly bonding all sides of the carton to form a solid packaging shell, protecting the products from bumps and collisions during transportation and storage. The production of some paper gift boxes and color boxes also depends on it to complete the delicate corner bonding, making the packaging box beautiful and durable and adding a sense of refinement to the gift.
