EVA Hot-melt adhesive is an environmental protection chemical product. Wire drawing occasionally occurs when heating, which affects work efficiency and beauty. What are the factors that contribute to this cause? Let's get to know together

1. If the temperature of the Hot-melt adhesive machine is too low, the thinner of the glue solution will increase and lead to wire drawing. Therefore, it is necessary to consult the sizing temperature first. If the temperature is too low, the temperature can be increased appropriately.


2. The high cohesion of Hot-melt adhesive will also increase the probability of resistance to deformation during gel construction, which is not easy to break, and the wire drawing is obvious; If the cohesion is small, it is easy to break and not easy to fly the wire. Therefore, when the viscosity is sufficient, it is beneficial to choose the one with low cohesion to reduce wire drawing, or to increase the construction temperature to reduce wire drawing.


3. The fluidity and curing time of Hot-melt adhesive are also related to wire drawing. Liquidity involves the design of formulas, the proportion and composition of materials, etc. However, if the curing time is short, it is easy to stop flowing, and the probability of wire drawing is very low,


These are the reasons why EVA Hot-melt adhesive can lead to wire drawing. If this phenomenon occurs, it can be dealt with promptly.
