1. Introduction
The hot melt adhesive for furniture is a kind of adhesive specially used for artificial plate paste, which is an environmentally friendly and solvent-free thermoplastic adhesive. When the hot melt adhesive is heated to a certain temperature, it is transformed from a solid state to a molten state, and when it is coated to the surface of the wood-based panel substrate or edge sealing material, it is cooled into a solid state, and the material and the substrate are bonded together.
2. Ingredients
The basic resin of hot melt adhesive is the copolymerization of ethylene and vinyl acetate under high temperature and pressure, that is, EVA resin. This resin is the main component of the production of hot melt adhesive, and the proportion and quality of the basic resin determine the basic properties of hot melt adhesive.
3. Application
More and more varieties of hot melt adhesive, more and more widely used, can be bonded leather, glass, metal, wood, luggage plastic, medical, textiles, etc., but mainly used in packaging corrugated paper and thick cartons, books wireless binding and woodworking welt.
Ethylene market is full of enthusiasm
In 2007, the domestic price of ethylene oxide experienced a steady and significant upward trend. At the start of the year, the price stood at 12,500 yuan per ton, and by November, it had surged to 17,500 yuan, reaching a record high. Notably, the sharp increase of over 1,500 yuan in November drew considerable attention from industry observers.
Despite a growing production capacity and output of ethylene oxide in China in recent years, and an expected continued rise in the coming years, the demand from sectors like polyester and surfactants has outpaced supply. As a result, the tight supply situation is unlikely to improve in the short term.
One key factor contributing to this imbalance is the large-scale production facilities but limited actual output. Currently, there are 12 ethylene oxide production units in China, with most operating alongside ethylene glycol plants. In 2007, total ethylene oxide capacity reached 2.1 million tons. However, many of these facilities do not fully produce ethylene oxide, instead focusing on ethylene glycol. As a result, only about 33% of the total capacity actually produces ethylene oxide. The real output was approximately 650,000 tons that year, showing a modest increase from 2006, but still insufficient to meet market needs.
Another challenge lies in the geographic concentration of production. Most ethylene oxide facilities are located in Jiangsu, Zhejiang, and Shanghai. Major players such as Nanjing Yangtze-BASF, Sinopec Yangzi Petrochemical, and Shanghai Petrochemical have significant capacities, accounting for nearly 58% of the national total. This concentration makes the region highly sensitive to supply fluctuations, which can ripple across the entire domestic market.
Additionally, the physical properties of ethylene oxide—its low boiling point at atmospheric pressure (10.7°C)—make long-distance transportation risky, increasing the likelihood of self-explosion. Therefore, relying on imports to fill the supply gap is not feasible. Domestic production remains the only viable solution.
On the demand side, the growth of downstream industries, particularly in ethylene glycol, synthetic detergents, and specialty chemicals, has been rapid. Ethylene oxide is widely used in the production of ethoxylates, pyridazines, ethylene carbonates, and hydroxyethyl compounds, which find applications in sectors such as textiles, pharmaceuticals, and industrial cleaning. The demand for fine chemicals derived from ethylene oxide has been rising at an annual rate of around 10%.
Moreover, the import of downstream products has surged, with over 70% of domestic ethylene oxide production directed toward ethylene glycol, glycol ethers, and ethanolamine. By December, the spot price of imported ethylene glycol hit an all-time high of $1,700 per ton, with analysts predicting further increases. Since 2003, more than 2.4 million tons of ethylene oxide-derived products have been imported, highlighting a persistent supply-demand gap.
Industry experts emphasize that the domestic market for ethylene oxide is vast and holds great potential, but requires urgent development. They recommend accelerating the adoption of advanced foreign technologies, investing in large-scale ethylene oxide/ethylene glycol units, and promoting domestic innovation in reactor and boiler design to enhance production efficiency and ease the supply shortage.
