Are the "viscosity" and "stickiness" of hot melt adhesives a concept?

Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Each type of hot melt adhesive can be divided into different models according to melting point, width, thickness, or gram weight, so their properties are also different.

In recent years, with the application of environmentally friendly hot melt adhesives more and more widely, its performance has once again attracted the attention of consumers. In order to reduce problems during use, Purking Hot Melt Adhesives believes that it is essential to understand the performance and application range of hot melt adhesives in advance.

 

What are the characteristics of Purking hot melt adhesive?

In the process of use, the characteristics of Weiwang hot melt adhesive are very prominent. No pungent smell, no solvent and no volatility, 100% solids content, almost no worries.

At the same time, it contains environmentally friendly ingredients, which greatly improves the environmental protection performance and hardly pollutes the human body and the environment; before leaving the factory, it has been tested for environmental protection performance and has obtained a number of international environmental protection testing marks, customers can use it with confidence; Purking Cooperate with many powerful brand suppliers for hot melt adhesive, so you can rest assured.

Purking Hot Melt Adhesives focuses on the research of environmentally friendly hot melt adhesives, and provides customized environmentally friendly hot melt adhesive application solutions. Books, building materials, food-related industries and other fields.

Are the "viscosity" and "stickiness" of hot melt adhesives a concept?

When many customers consult Purking hot melt adhesive, they always ask a question: "Is the hot melt adhesive strong sticky?" This strong sticky is "sticky". In the absence of a clear sticky material, it is impossible to directly say whether the hot melt adhesive is strong or not. Hot melt adhesives are only suitable or not, and there is no stickiness. This is a misunderstanding of many customers in consultation.

Strictly speaking, "viscosity" and "stickiness" are two properties. The so-called viscosity. Viscosity is an important parameter of hot melt adhesive. Viscosity is also called viscosity, which refers to the degree of thinness of hot melt adhesive in the molten state, and has a direct relationship with temperature and fluidity. When the temperature is high, the fluidity is better; the temperature is low, the fluidity is poor.

The lower the viscosity, the better the fluidity of the hot melt adhesive, the easier it is to release the glue, and the less wire drawing. The disadvantage is that the internal torque is not enough, which will easily lead to the separation between the glue and the glue. The higher the viscosity, the worse the fluidity of the hot-melt adhesive, the higher the melting point, and the more wire drawing. The advantage is that the internal torque is sufficient, and there will be no problem of direct separation of glue and glue. Only when you know exactly which specific material to stick, can you compare which glue stick has better stickiness.

       

Viscosity refers to the performance of bonding, which has a great relationship with the amount of glue applied. During use, the larger the area of glue application, the better the adhesion. If the industrial field has higher requirements on the adhesiveness of the adhesive, the amount of glue can be increased appropriately. When the amount of glue is more, the adhesion will naturally be improved.

Different brands of environmentally friendly hot melt adhesives have different preparation recipes. The viscosity and viscosity of most hot melt adhesives are similar, which is also the most basic performance of environmentally friendly hot melt adhesives. The cost is not too high, the performance is not bad, and it is suitable for heavy use.

 

As a professional hot melt adhesive manufacturer, Purking Hot Melt Adhesive always believes that the more expensive the hot melt adhesive is, the better the fit is. Purking Hot Melt Adhesive is committed to providing customers with the most suitable solutions with favorable prices and high-quality products.

In the future, Purking hot melt adhesive will keep up with the development trend of the industry, actively improve its own equipment and innovate technology, and strive to become a hot melt adhesive industry with environmental protection advantages, technological advantages, product advantages, and brand advantages.
