Types of hot melt adhesive used for writable kraft paper tape

Article provenance:未知 Popularity:Time:2020-07-19 00:31
Writable Kraft paper tape manufacturers introduced that the development of technology stems from the change of the industry. In the future, under the trend of globalization of the hot melt adhesive industry, the demand will be more diversified, and the gradually large-scale hot melt adhesive enterprises will also have enough strength to do basic research, so as to gain advantages in the market with serious product homogeneity. Therefore, the development of technology is almost inevitable.

High strength hot melt adhesive
Bonding strength is the core performance of adhesive. If hot melt adhesive wants to be applied to some occasions with high strength requirements, especially those with large structural stress, the bonding strength must be improved.
Strong polarity and good wettability are the characteristics of high adhesive strength. Because of the lack of solvent, the fluidity and wettability of hot melt adhesive are short plates. The polarity and wettability of hot melt adhesive should be improved from the polarity and wettability of hot melt adhesive.

High speed hot melt adhesive
The high efficiency of hot-melt adhesive is generally recognized, because as long as the hot-melt adhesive cools, it will harden and form adhesive. The adhesive speed of cigarette tip stick can reach 20000 pieces / min, book binding can reach 18000 copies / hour, and the production of diapers can reach 1000 pieces / min.
In the future, it is possible to further improve the hot melt adhesive sizing speed and expand this advantage, mainly by accelerating the hardening speed, improving the thermal viscosity, reducing the specific heat of materials, and optimizing the equipment.

Low temperature hot melt adhesive
Sizing temperature is one of the most concerned problems of material engineers. Low sizing temperature can not only reduce the damage of materials, prolong the service life of equipment, save energy consumption, but also reduce the public welfare effect of carbon emission. Therefore, low temperature hot melt adhesive will be a promising research direction.

Low density hot melt adhesive
In many cases, reducing material density to achieve lightweight has many advantages, such as reducing energy consumption and saving resources. In fact, the adhesive strength is more dependent on the bonding area than the weight of the adhesive itself, which makes the low density hot melt adhesive become a reliable research direction.
Low density can be achieved not only by improving material density (e.g. using polyolefin materials), but also by manufacturing processes, such as foamed hot melt adhesives.

Odorless hot melt adhesive
In the situation that people pay more and more attention to health, especially in automobile, sanitary materials, food, toys, furniture and other industries, odorless hot melt adhesive is the best product to reduce the doubts of end consumers.
Odor free should be realized by improving the raw materials, reducing small molecular substances as far as possible, using low odor or even odorless raw materials, such as hydrogenated rosin ester.

Material based hot melt adhesive
Through special molding process, the hot melt adhesive will be made into film, network, strip, linear material, which will become a development trend of hot melt adhesive. Nowadays, the market of hot-melt adhesive film, hot-melt adhesive mesh film, hot-melt adhesive tape and hot-melt adhesive line is growing rapidly. The combination of such hot-melt adhesive materials and other materials is more conducive to the realization of large-scale production and clean production of downstream enterprises.
- 7 -
Degradable hot melt adhesive
Environmental protection is a major trend, and environmental protection is also a relative concept. Although hot melt adhesive belongs to environmental protection adhesive, it is only limited to the harmless environmental protection of human body, not in the recycling or degradable level of environmental protection. In the future, if we can develop the hot melt adhesive which is easy to recycle or can be naturally degraded, it will have a good development prospect.
