The types of hot melt adhesive include: ethylene vinyl acetate (EVA) adhesive
Ethylene vinyl acetate (EVA) is a polymer based material used for standard packaging of industrial hot melt adhesives. EVA produces high-performance and highly competitive packaging hot melt additives. Ethylene vinyl acetate is considered the primary choice for many applications as it offers one of the largest performance ranges among all currently available applications. Ethylene vinyl acetate can function in both traditional and low-temperature hot melt adhesives.
Polyethylene is a polymer substrate suitable for pallet sealing and cardboard box applications. These adhesives have an extremely low odor, light color, and are easy to peel off from metal surfaces, making them easy to clean. Polyethylene is not suitable for bonding substrates, therefore it is suitable for use at traditional application temperatures.
Metallocene polymers have existed for decades. They combine with other components to provide great stability forhot melt adhesiveproducts. They provide storage temperature intensity in both hot and cold conditions. They have become the fastest-growing polymer base. Metallocene minimizes the decomposition caused by thermal exposure and reduces carbonization, while expanding the cold and hot bonding properties. Some of the products available today contain metallocenes in their adhesives; However, many variants with different stability, price points, and bond performance are different from the original product.
Amorphous poly (alpha olefin) (APAO) is mainly used in areas with long working hours or where it needs to be bonded to plastics. These types of adhesives have a sticky, soft, and very flexible texture. This makes them a very good choice for assembling products, including adding foam for corrugated packaging protection and bonding corrugated plastic containers.
Polyamide adhesives are excellent in places where high temperature resistance is required. They are also useful in situations where rapid assembly strength, solvent and oil resistance are required. Polyamide is considered an excellent choice for wood, filters, and other applications that require high performance. Polyamide requires extreme temperature applications of approximately 400 ° F (204 ° C). However, like other types of adhesives, they do not exhibit significant stability when heated.
Book edge glue is an important but often overlooked application of book binding glue. Simply put, it refers to using a thin layer of hot melt adhesive to bond the inside of the cover to the first, last, or final page of the book. Although side bonding is much smaller in volume than spine bonding, […]
How often is it appropriate to clean the glue pot? The cleaning cycle of the glue pot depends on the amount and type of glue used. General recommendation: Thoroughly clean every 2-3 months under continuous production conditions; Intermittent use (less than 3 days per week) can be extended to 4-6 months. But in the following […]
How can EVA hot melt adhesive improve the safety of boxes and cartons? In addition to increasing production line speed to meet greater packaging demands, many box and carton factories hope to improve worker safety. Although this may require ensuring the use of appropriate hot melt adhesive at all times, the correct adhesive can have […]
Hot melt adhesive particles are solid adhesives that are heated above their melting point before being applied to a substrate. According to the desired application, hot melt adhesive has various appearances and textures. They do not require a curing or drying period as they quickly solidify when cooled to the freezing point. Therefore, hot melt […]
