Hot melt adhesive is ubiquitous, yet constantly invisible. Hot melt adhesive manufacturers’ products are widely used in books, pearl cotton, clothing, shoes, handbags, cardboard packaging, etc. When choosing to use hot melt adhesive, I usually don’t pay attention, but when problems arise, it can be very embarrassing. So whether it’s book binding manufacturers, shoe and hat luggage manufacturers, pearl cotton manufacturers, or clothing manufacturers, they are all more cautious when choosing hot melt adhesive manufacturers.
So, what specific issues should we pay attention to when choosing a hot melt adhesive manufacturer?
1. Color and Transparency of Hot Melt Adhesive:
Hot melt adhesive needs to play a bonding role, and the higher the transparency of hot melt adhesive, the better. So when choosing hot melt adhesive, it is important to consider its transparency and color. Our company produces hot melt adhesive for books and periodicals, graphic hot melt adhesive, and pearl cotton hot melt adhesive with light colors, including colorless transparent, light yellow transparent, and milky white.
2. Viscosity of Hot Melt Adhesive:
As a hot melt adhesive, viscosity must be considered. Ordinary users can evaluate hot melt adhesive products on the market from three dimensions: initial adhesion strength, peel strength, and holding strength, and select suitable hot melt adhesive products. In addition, due to the wide application of hot melt adhesive, the hot melt adhesive used also needs to be able to bond multiple materials, and even some difficult to bond materials and rough surface materials can be practical.
III. Weather resistance of hot melt adhesive:
There are many changes throughout the year, in addition to temperature and humidity. This also puts forward requirements for the use of hot melt adhesive, mainly reflected in adapting to the temperature range, selecting suitable hot melt adhesive, and being able to be used within the range of -10 ℃~50 ℃, achieving no change of adhesive during seasonal changes.
4. Hot melt adhesive safety and environmental protection:
Safety and environmental protection are the themes of modern society and a major reason why hot melt adhesives stand out in the adhesive market. Hot melt adhesive often interacts with users, so environmental protection is necessary. Hot melt adhesive is the abbreviation for hot melt adhesive. Due to its high bonding strength, fast speed, non-toxic and odorless advantages, it belongs to environmentally friendly adhesive products.
When choosing hot melt adhesive, you can communicate with the hot melt adhesive manufacturer. Excellent manufacturers will recommend suitable hot melt adhesive products based on the user’s product characteristics, budget, glue machine, season, and other factors.
The packaging hot melt adhesive is heated to become liquid. Apply the liquid to the initial surface by extruding, spraying, or rolling the specified amount, and then expose it to a brief “open time” to achieve optimal temperature and “humidity” for bonding to the initial surface. After the designated opening time, the two surfaces come […]
It is crucial to choose the appropriatehot melt adhesivefor each application. The adhesive required to complete a specific task may vary greatly, so it is important to understand which adhesive is most suitable for your application. The five commonly used types of main polymer substrates are the main components of our paper boxes and box […]
The weather resistance of hot melt adhesive affects its application effect. Hot melt adhesive manufacturers need to adjust the heat resistance of hot melt adhesive according to different application environments to achieve ideal application performance. The heat resistance of hot melt adhesive is closely related to its softening point. Hot melt adhesives with good heat […]
What hot melt adhesive is used for book binding? Nowadays, EVA type hot melt adhesive is commonly used to stick the side of books, and PUR type hot melt adhesive is also available, but the cost of using PUR type hot melt adhesive will be slightly higher. The process of gluing the spine is as […]
