The three development fields of the hottest phenol

  • Detail

The three development areas of phenolic resin demand improvement are clear.

the demand for phenolic resin is steadily increasing and the development has entered a new stage. Although new applications and new demands emerge, the three future development directions are still clear. With the continuous growth of demand in these fields, the phenolic resin Market in China is steadily improving

I. in the field of casting materials

in recent years, the downstream industries have significantly improved the performance requirements of phenolic resin. Sand mold materials for casting, refractory materials for metallurgy, sand consolidation materials for oil drilling, thermal insulation and decoration materials for construction, adhesives for wood processing, reinforcing and tackifying additives for rubber industry, plastic packaging materials for electronic industry, etc. all show special requirements for phenolic resin. As a result, the product structure of some industries has been improved. For example, the molding sand binder in the foundry industry has significantly improved the casting process and the casting quality since a large number of phenolic resins have been used in China

at present, the consumption of phenolic resin for casting is increasing at an average annual rate of 15%. Phenolic plastic is the traditional consumption field of phenolic resin, accounting for more than 30% of the total consumption of phenolic resin, which is significantly higher than the average level of foreign countries. Compared with phenolic resin for industrial use, phenolic plastic is easy, though difficult; It still accounts for the majority of phenolic resin consumption, but the proportion is shrinking

at present, the types of phenolic molding compounds in China include phenolic molding powder, rapid curing molding powder, glass fiber reinforced molding materials and phenolic foaming materials. In recent years, the development of phenolic plastics in China has slowed down, the market demand is not booming, especially the low-grade products are unsalable. With the development of injection molding technology, phenolic injection molding has developed well in recent years, and the market demand is increasing year by year; High grade heat-resistant and reinforced phenolic plastics also show great market potential

II. Field of insulating materials

in the field of insulating materials, phenolic resin will still be the preferred binder in thermal insulation and sound insulation materials. With the use of phenolic foam as a new thermal insulation and sound insulation material, it can be asserted that the consumption of phenolic resin in this field will increase greatly without moisture absorption, crystal water (except for flame retardant volume effect, also known as small size effector), acid and alkali resistance

III. composite material field

the application of phenolic composites in aerospace, military equipment, ships, transportation, construction, mining and many other fields will be eye-catching. In addition, China's coated abrasive tools have made great progress in recent years, and the output is increasing year by year. Phenolic resin binder will have a great demand in this field

in recent years, phenolic resin and plastics have made new progress in product performance and quality, development of new technologies and varieties, production process and equipment, basic theoretical research and testing methods; In China, various grades of phenolic resin can be produced in batches, and composite materials can be manufactured by different processes, which has reached a certain technical level. In the aspect of new phenolic resin and its composites, the development and research of SMC system, flame retardancy and new resin have also begun. Therefore, the traditional phenolic resin industry will enter a new stage of development. In the future, the development directions mainly include: developing high activity phenolic resins for SMC, pultrusion, etc., and developing SMC system (including curing, thickening system and reaction mechanism); Study the composite technology and process of glass fiber, carbon fiber, aramid fiber and hybrid fiber; Development of high performance phenolic resin and its composites (such as phenolic FRP); Develop applications in construction, transportation, mining, etc
