Application of High Melt Wax for Hot Melt Adhesives
With the development and progress of social economic technology, continuously improvedment of fractional distillation, micronization and modification technology provides technical support for a reliable role in the practical application of high melting point waxes with high melting point, low oil content, high stability, low melt viscosity, narrow melting point range and low mobility and penetration. It is widely used in food and cosmetics and hot melt adhesives.
At high temperatures, the melting temperature range and the type of wax added directly determine the nature of the hot melt adhesive. The curing time and initial solidification temperature of the hot melt adhesive are affected by the crystallinity and freezing point of the wax added. Its tensile properties and plasticity also have a certain influence. The application of the high melting point wax in the hot melt adhesive can improve the adhesive temperature of the hot melt adhesive, so that the adhesion of the hot melt adhesive can be effectively prevented during storage and transportation. At the same time, the viscosity of the resin and the polymer can be greatly reduced by the low viscosity properties of the high melt wax for hot melt adhesives. This not only improves the efficiency of resin mixing, but also facilitates the transfer of the hot melt adhesive in the pumping mode, and also maintains the surface wettability of the resin and the polymer within a certain appropriate range. The production and sales of hot melt adhesives with high melting point wax are quite considerable. The average annual growth rate of China has reached 38% in the past five years, and the application range of hot melt adhesives has been expanding. It has played a considerable role in the life and production of China.
