(Summary description)What is the difference between chemical film Gangbao, Shuigangbao and low temperature hot melt glue Gangbao?

　　 The main difference is:

1. The material of the low-temperature hot-melt adhesive Gangbao film is memory elasticity after setting. In the production process, it pays more attention to hardness and toughness, waterproof and non-deformation. The traditional chemical Gangbao is hardened after setting, and it will soften after a long time. Deformation;

2. Gangbao film is generally used between shoe fabrics and linings to shape the shoes. The materials used in traditional leather pulp water and chemical films Gangbao are a bit like cardboard, using soaking softening and foaming. Solvent (toluene) softening method, the product is thicker, the molding time is long, and the elasticity is very poor; while the low-temperature hot melt adhesive film has high hardness and strength, good toughness, and can meet the requirements of heat resistance and cold resistance at the same time, and can be compatible with Other additives are well integrated, have a wide range of uses, strong adhesion, and can adhere to many different substrates.

　　3. Shuigangbao needs sizing in the application process, which requires many operating procedures, time-consuming and laborious, and not economical;

　　The low-temperature hot-melt adhesive Gangbao has high melt viscosity, does not require sizing, and is simple to operate. It can be bonded directly through the oven, completely breaking the traditional complex operation, saving time and effort, and conforming to market economic benefits.

4. The traditional skin slurry water port treasure and chemical tablet port treasure are harmful to the body, irritating to the skin and mucous membranes, and have side effects on the central nervous system. The low temperature hot melt glue port treasure is non-toxic and tasteless in the production process and belongs to the international Sexually recognized environmentally friendly materials.

　　 China is the world's largest footwear manufacturing base. In the future, the development of China's footwear industry will inevitably move from the low-end market to the mid-to-high-end market, and product upgrading is an inevitable trend. With the progress of society and the continuous improvement of people's living standards, on the one hand, people's demand for shoe materials will continue to increase, on the other hand, people will pay more attention to environmentally friendly, energy-saving, and higher value-added shoe materials. At present, as the most important new material for shoemaking, low-temperature hot-melt adhesive Gangbao will continue to increase in demand. It is an inevitable result that low-temperature hot-melt adhesive Gangbao will replace the traditional chemical film Gangbao in the market.
