Special Chemical Industry,是什么?
Specialty chemicals are a category of relatively high valued,rapidly growing chemicals with diverse end product markets.Typical growth rates are one to three times GDP with prices over a dollar per pound.They are generally characterized by their innovative aspects.Products are sold for what they can do rather than for what chemicals they contain.Products include electronic chemicals,industrial gases,adhesives and sealants as well as coatings,industrial and institutional cleaning chemicals,and catalysts.Coatings make up about 15 percent of specialty chemicals sales,with other products ranging from 10 to 13 percent.
Specialty Chemicals are sometimes referred to as "fine chemicals"
