China PUR glue demand in recent years have increased, including automotive, electronics, packaging, construction applications have increased significantly.
Silicone, polyurethane, epoxy resin and other high-performance synthetic adhesives and hot melt adhesives, VAE emulsion, acrylic emulsion and other environmentally friendly safety adhesives have a greater growth. China's synthetic adhesive industry for the actual situation, the industry believes that the future development of the focus, first, the development of low formaldehyde emission of urea-formaldehyde resin adhesive. Such adhesive production is currently about 1/3 of the total output, but the production process level in general, we must further improve the technology and reduce production costs. Second, the development of polyamide adhesive. Polyamide adhesives in the automotive, construction, footwear, packaging applications have a wide range of prospects, which is a very promising and have a large potential market varieties. Third, silicone adhesive. The current world developed countries in the construction industry mainly use silicone sealing adhesive, and gradually become the leading varieties.
Fourth, automotive PVC plastic plastic adhesive. In the automotive production, PVC plastic adhesive is the main adhesive, in 2000 the domestic demand is about 20,000 tons. Fifth, hot melt adhesive. Hot melt adhesives are mainly used in the field of clothing, packaging and printing, domestic production is less, some rely on imports. Six is the epoxy resin adhesive. At present, domestic and electronic epoxy resin adhesive is of poor quality, mainly dependent on imports. Seven is a safety glass with polyvinyl butyral adhesive. Such adhesives are mainly used in the construction and automotive industries.
Hot melt adhesive is the most common synthetic adhesive, with thermoplastic resin as the matrix. It is usually a single component, with a very fast curing speed, for a variety of materials, including some other adhesives difficult to glue the non-polar plastic, have good wetting and high bonding strength. It is rich in raw materials, low prices, it has become one of the most promising adhesive.
