Hot Melt Adhesive Grade Polycaprolactone
Product name：Hot Melt Adhesive Grade Polycaprolactone
Product name(cn)： 热熔胶级聚己内酯
Hot melt adhesive grade polycaprolactone is a kind of polyester polymer material, suitable for the production process of reactive moisture curing hot melt adhesive (PUR), and also suitable for the production process of physical curing hot melt adhesive, without inorganic powder and other auxiliary materials. PCL is a semi-crystalline material with low melting temperature, low activation energy for making hot melt adhesives, low melt viscosity, relatively low melt surface tension, strong penetration, and good toughness after curing, which is beneficial to textile fabrics, leather, Bonding of wood, etc. The hydroxyl group on the molecular weight chain segment of the hot melt adhesive grade polycaprolactone can react with the isocyanate group to form a firm chemical bond, which is especially suitable for reactive moisture curing hot melt adhesive system.
