Furniture edge sealing glue can be divided into three categories according to the different base materials:
HMPU (polyurethane) base material hot melt adhesive, it is a kind of hot melt adhesive with the best performance, and it is the guarantee of high quality sheet edge sealing. It is expensive and requires special usage.

China, as the second largest producer of instrumentation in Asia, has a variety of types and comprehensive development, but there are still bottlenecks.
I. At present, China is undergoing an important historical stage of changing the industrial structure through technological innovation and upgrading the national economy from all aspects. Measuring with instruments is a means for people to obtain information from nature. At present, the vast majority of China's advanced instrumentation rely on imports, but the most advanced foreign instruments and instruments are generally developed in the laboratory, the market can not buy.
Second, although in 2011, there were more than 5,000 enterprises in the entire industry, achieving a total industrial output value of 525.3 billion yuan, sales revenue of 511.6 billion yuan, and total profit of 38.7 billion yuan. However, the quality of the company still needs to be improved.
Although instrumentation and instrumentation have achieved high levels of development in recent years, they have been largely affected by GDP. A single unhealthy model that pursues the pace of enterprise development neglects product technology innovation and product quality, leaving many unhealthy factors in the industry.
Fourth, another feature of the instrumentation industry: The import and export deficit is relatively large, and it is the largest deficit among the 13 industries in the machinery industry. China continues to lag behind developed countries.
EVA (ethylene-vinyl acetate copolymer resin) base material hot melt adhesive, this hot melt adhesive can be divided into two types with filler and without filler. Using EVA as the base material is the most common production technology for furniture edge sealing adhesives, and its main limitation is poor heat resistance. The ambient temperature of panel furniture sealed with EVA hot melt adhesive shall not be higher than 120°C;
POL YAMIDE (polyamide) based hot melt adhesive, this hot melt adhesive has good heat resistance and fast curing characteristics, the main disadvantage is that it is expensive.
1. Viscosity of furniture edge sealant
The viscosity of furniture edge sealing glue does not directly reflect the performance of the glue. In general, the higher the viscosity of the furniture edge sealant, the better its initial tack strength, but the worse the coating performance. Low-viscosity hot melt adhesives have a smaller amount of glue and better wetting properties. Some hot melt adhesives with low viscosity and fast curing speed may also have high initial tack strength.
2. Density of furniture edge sealing glue
The density of furniture edge sealant is generally 0.95-1.6g/cm3, and its density depends on the amount of filler.
3. Softening point and use temperature of furniture edge sealing glue
The softening point is an indicator of the heat resistance of the furniture edge sealant. The higher the softening point, the less likely the furniture edge sealant will melt. At the same time, softening point is also an important aspect to measure the temperature resistance of panel furniture.
4. The opening time of the furniture edge banding glue and the feeding speed of the edge banding machine
Furniture edge sealant is widely used in the market because of its solvent-free, water-resistant, and environmental-friendly features.
