1. Low pressure injection hot melt adhesive
Low pressure injection molding hot melt adhesive has broken through the use limit of general traditional hot melt adhesive. Its normal operating temperature is only 110°C~130°C, and the use temperature of low-pressure injection molding hot melt adhesives is more than 30°C lower than traditional hot melt adhesives. Compared with traditional hot-melt adhesives, the low-pressure injection molding hot-melt adhesive has a significantly lower viscosity value, ensuring that it can meet the requirements of various coating processes under low-temperature operating conditions. The direct benefit of low pressure injection molding hot melt adhesive is to save electricity costs and machine maintenance costs. A large number of practical applications show that the same hot melt machine, using low pressure injection molding hot melt adhesive can save customers about 15% of electricity bills. However, because the low-pressure injection hot melt adhesive has almost no aging phenomena such as skinning and carbon deposition at its normal operating temperature of 110°C to 130°C, the maintenance cost of the machine is greatly reduced. More importantly, the low-pressure injection molding hot melt adhesive will not scald the PE film.
2. Hydrophilic hot melt adhesive
Traditional hot-melt adhesives are generally hydrophobic, and hydrophilic hot-melt adhesives are made hydrophilic through special formulations. Each application of hydrophilic hot-melt adhesives can give the product higher added value and make the product production In the current highly competitive market, manufacturers effectively differentiate their products and ultimately win consumers.
3. Other new technologies of hot melt adhesive
In addition to the above aspects, the new hot melt adhesive technology also includes: anti-oil hot melt adhesive; hot melt adhesive suitable for high frequency spraying; high wet strength hot melt adhesive; degradable hot melt adhesive, etc.
