Udviklingstendensen for smeltelim

Smeltelim har været tilgængelige i århundreder, dogsmeltelimbaseret på syntetiske polymerer begyndte ikke at vises på markedet før i 1950'erne. Verdens årlige produktion af hotmelt-klæbemidler har været en opadgående tendens med mere og mere varierede sorter og bredere anvendelser.

        Since 1988, the world production index of smeltelim has been higher than that of solvent-based adhesives and water-based adhesives. Hot melt adhesive has the advantages of pollution-free, suitable for automated production lines, fast operation speed and low cost. It is gradually replacing various traditional bonding methods or adhesives, and has received more attention. The performance of hot melt adhesives is gradually improved and improved through grafting modification, blending modification and reaction curing technologies. New varieties and new processes of smeltelim are also constantly developing, showing a bright future.
