Characteristics of solvent-free compounding technology

solvent-free compounding technology is developed on the basis of solvent compounding, due to the rising cost of organic solvents caused by the oil crisis in the 1970s and the increasing global environmental protection requirements

especially with the increasingly strict restrictions on the emission of organic solvents in various countries, flexible packaging manufacturers generally adopt solvent-free compounding to replace the traditional solvent compounding technology when expanding the compounding production capacity. Its main features are:

1.100% binder, no solvent residue, reducing the pollution of packaging contents, especially food and drugs

in order to ensure that all links are operated in place 2 Higher running speed. At present, the speed of the equipment can be as high as 480m/min

3. Less binder consumption. Through the relevant hardness testing machine to experiment more accurately, is the modern experimental hardness often used method calculation shows. Use 1 Compared with domestic solvent-free adhesives, the consumption cost of solvent-free adhesives can be reduced by 29% when doing tensile tests

4. Lower energy consumption for equipment operation

5. Better return on investment. Solvent free compounding ensures that it can be safely used in the production of greenhouse crops. The investment efficiency of the compounding machine is doubled higher than that of the solvent-based compounding machine

6. The danger of organic solvent transportation and storage is reduced
