Tá greamacháin leá te ar fáil, áfach, le haghaidh treochtaígreamacháin leá tebunaithe ar pholaiméirí sintéiseacha níor thosaigh siad le feiceáil ar an margadh go dtí na 1950idí. Tá aschur bliantúil greamachán hotmelt ar domhan ag dul in airde, le níos mó cineálacha éagsúlaithe agus feidhmchláir níos leithne.

        Since 1988, the world production index of greamacháin leá te 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 greamacháin leá te are also constantly developing, showing a bright future.
