Polyurethane adhesives will replace traditional products due to their low cost and good performance. Hot melt has been widely developed during book binding.
Mainly because of the unprecedented development in the production of paperback books in China in recent years, EVA hot-melt adhesives have been widely used in book binding because of their good adhesion and elasticity. However, its high price and memory characteristics, so the development of polyurethane hot melt adhesive will replace the traditional products. Polyurethane hot melt adhesive has simple production process, low cost, better elasticity and toughness of adhesive, high adhesive strength, can be repeatedly used for melting, and has high product utilization rate and has a wider application prospect.
