Although the EVA hot -melt glue film and TPU hot -melt glue film have a lot of common points in terms of physical forms, they are completely different in terms of attribute characteristics.
The difference in product characteristics:
The water -resistant washing performance of the EVA hot -melt glue film is poor, pe wax flakes for Hotmelt adhesive and it is not resistant to dry cleaning. The characteristics of high temperature resistance are 80 degrees, and the low temperature resistance below 20 degrees;
The TPU hot -melt glue film has good water -resistant washing performance, high temperature resistance at 110 degrees, and low temperature resistance to minus 20 degrees; at the same time it also has better stretching performance.
The difference between melting points:
There are three main melting points of the EVA hot melt glue film, wax additive for rubber, which are 80 degrees, 90 degrees and 110 degrees. Among them, the 80 -degree melting point EVA hot -melt glue film is widely used.
There are many types of melting points of TPU hot melting glue film. The low -melting points can achieve 65 degrees. The high melting point is about 180 degrees. The span is large and the application is wider!
The difference in industry in the industry:
EVA hot -melt glue film is mainly suitable for: EVA crafts, floor mats, PET materials, wall cloth back glue, non -woven fabric, photovoltaic panel materials, and diving clothing.
The TPU hot -melt glue film is mainly suitable for: leather, shoe, super fiber, mobile phone leather sleeve computers, assault clothes, sports fabrics, paper, ceramics, plastics and textiles.
The difference between EVA hot -melt rubber film and TPU hot -melt glue film is far more than these articles mentioned in this article. For users, focusing on their differences in application.
Although EVA adhesives VAry in properties depending on their specific formulations, in general, they bond to the broadest range of substrates, function in one of the widest temperature range for hot melt adhesives, and, on top of everything else, are the most affordable. EVA hot melt adhesives generally require an application, or melting temperature of 350 degrees F, and have a wide viscosity range of between 900-3,000 CPS.
For the most part, EVA adhesives have a relatively fast set speed. However, it is important to remember that if you are using a formulation with a higher ratio of vinyl-acetate, the set time will be somewhat longer. EVA adhesives can function in temperatures as low as -40 degrees F and as high as 160 degrees F, again depending on the formulation.
Application of Hot Melt Adhesive EVA 8001 A
Paper industry
In the paper industry, EVA adhesives play a crucial role in ensuring that products are durable and well-bonded. They are especially useful in binding books, attaching labels, and even in the production of laminated paper products.
Woodworking
EVA's strong bonding capability is inVAluable in woodworking. Whether it's for furniture assembly, bonding veneers, or even in the production of cabinetry, EVA ensures that wooden components remain firmly attached.
Assembly
In the assembly line, speed and efficiency are of the essence. EVA adhesives, with their fast set speed, are ideal for rapid assembly processes, ensuring that products are manufactured at a swift pace without compromising on the quality of bonding.
Automotive
The automotive industry demands adhesives that can withstand VArying temperatures and conditions. EVA adhesives are used in the interior assembly of vehicles, bonding fabrics, foams, and other components. Their resistance to temperature fluctuations makes them a reliable choice for this sector.
Packaging
The packaging industry is perhaps one of the most significant beneficiaries of EVA adhesives. Their ability to adhere to a diverse range of materials, from waxes to aqueous coatings, makes them indispensable. Applications include carton sealing, package labeling, and paper conversion, ensuring that products are securely packaged and labeled.
Footwear
EVA adhesives have also found their footing in the footwear industry. They are extensively used in bonding VArious parts of a shoe, especially the sole. Given the wear and tear shoes undergo, a robust adhesive like EVA ensures longevity. Whether it's sports shoes, formal footwear, or casual sandals, EVA adhesives play a pivotal role in their construction.
Polyethylene
These polymer bases work well for most case, carton and tray sealing applications. Polyethylene polymer based adhesives provide low odor, light color, and often release easy from metal for easy clean up if it gets on your equipment. It is not ideal for difficult to bond substrates and is only used at traditional application temperatures.
Metallocene
Metallocene polymers were introduced in the 90's. Combining these polymer bases with other premium components offered much greater stability while heated for application and provided storage temperature strength under very cold and hot conditions. This disruptive jump in reducing char and breakdown from heat exposure while expanding heat and cold bond performance made them the fastest growing polymer base since then. There are many variants of premium no char performance hot melts offered today. Evans recommends identifying which level of performance is needed rather than using the polymer metallocene as a designation of a hot melt type with low/no char performance. Some offerings marketed today may have some of this polymer in the adhesive but there are many variants with a wide range of price points, stability, and bond performance not equivalent to the originally introduced products.
Apao (amorphous poly alpha olefins)
Apao adhesives are best used where long open/working time or adhesion to plastics is desired . These adhesives offer a soft, tacky and flexible texture, making them an excellent choice for product assembly including adding foam protection to corrugated packaging and bonding plastic corrugated containers.
Polyamides
These adhesive excel where for very high temperature resistance, oil and solvent resistance, or quick assembly strength is desired. This makes them an excellent choice for filter, wood, and other high performance assembly applications. These adhesives require high application temperatures typically around 400f and do not have as much stability under heat as the other types of adhesives.
Material of Hot Melt Adhesive EVA 8001 A
Basic resin
The basic resin of hot-melt adhesive is ethylene and vinyl acetate copolymerized under high temperature and high pressure, namely EVA resin. EVA resin is the main component for making hot-melt adhesives. The proportion and quality of basic resin determine the basic performance of hot-melt adhesives (such as the adhesive capacity, melting temperature and adhesive strength of adhesives). Generally, the VA content is 18–33. Refers to (mi) 6–800, with low VA content, the higher the crystallinity, the higher the hardness. Under the same circumstances, the larger the VA content, the lower the crystallinity, the higher the elasticity. The selection of EVA melt fingers is also important. A large melting temperature and high wettability and poor permeability of the adherend. On the contrary, if the melting point is too large, the melting temperature of the glue is low, the fluidity is good, but the bonding strength is reduced. The choice of additives should choose the proper ratio of ethylene and vinyl acetate.
Tackifier
Tackifier is one of the main additives of EVA hot melt adhesive. When the basic resin is melted, it has a bonding force at a certain temperature. Adding a tackifier can improve the fluidity of the colloid and the wettability of the adherend, improve the bonding performance, and achieve the required bonding strength. General tackifiers include rosin, modified rosin (138 or 145), c5 petroleum resin, c9 petroleum resin, terpene resin, etc.
Viscosity modifier
Viscosity modifier is also one of the main additives for hot melt adhesives. Its role is to increase the fluidity of the colloid and adjust the solidification speed to achieve the purpose of fast bonding and firmness. Adding a viscosity modifier with a low softening point can achieve the purpose of good penetration and firm adhesion during bonding. Generally choose paraffin wax, microcrystalline wax. Synthetic wax (pe or pp), fossil wax, etc.
Antioxidant
The appropriate amount of antioxidant is added to prevent premature aging of EVA hot melt adhesive. Because the colloid will oxidize and decompose when the temperature is high, the addition of antioxidants can ensure that the bonding performance does not change under high temperature conditions.
Heating equipment
Using a hot glue gun or edge banding machine with a heated applicator, you can set and control the temperature within the recommended range.
Temperature control
Maintain the adhesive temperature within the specified range to ensure proper melting and bonding.
Preparation
Prepare the edge banding and substrate surfaces by cleaning and, if necessary, sanding to promote good bonding.
Application
Apply the eva hot melt adhesive evenly to the edge of the substrate or the back of the edge banding material, depending on your equipment and process.
Bonding
After applying the adhesive, quickly place the edge banding on the substrate, ensuring proper alignment. Apply pressure to form a strong bond.
Cooling and setting
As the adhesive cools and sets, it forms a strong bond between the edge banding and the substrate. This typically occurs within seconds to minutes, depending on the adhesive and environmental conditions.
