Hot melt adhesive products now on the market are basically traditional products, and many of the environmental performance requirements for hot melt adhesives are high. On this basis, it is necessary to improve the traditional performance hot melt adhesive, then both be improved by what method? 

Modification of existing varieties 

     By blending, grafting and other methods for the modification of existing varieties to improve the performance of hot melt adhesive. Such as stabilizers to prevent oxidation; tackifier to improve the adhesive strength; paraffin reduce the viscosity change the surface properties; various fillers can improve viscosity, melting point and bonding strength. Study various varieties ingredients, dosage, and formulations optimized to meet different needs. 

Accelerate the development of new products 

    Curable hot melt adhesives and hot melt adhesives are currently two major functional categories of new products on the market. The former is characterized by improved high temperature properties of hot melt adhesive, to raise the softening point above 120 ℃, thereby expanding its use; functional hot melt adhesive is for a specific occasion, you can achieve a specific function to meet the needs of all aspects of the use of a class glue. Such as water soluble or dispersible adhesives, hot melt sealant, hot melt pressure sensitive adhesive and the like. The following is a description of a hot melt sealant. It is a kind of polyisobutylene rubber as the base material of the one-component, solvent-free, no fog, not curing, with a permanent plastic first of the insulating glass sealant. Hot melt butyl sealant and sealing to maintain its plasticity over a wide temperature range, and the surface does not crack, do not harden. It glass, aluminum, galvanized steel, stainless steel and other materials have good adhesion. Because of its extremely low water vapor permeability, it can be configured with a resilient sealant system with excellent resistance to moisture. Features: good sealing effect, easy quality assurance; without curing period, save floor space; are environmentally friendly products, the use of non-waste, clean environment; saves time, materials, staff, reduce production costs. 
Development of high-performance hot melt adhesive 
    At present, except more general EVA, TPR class hot-melt adhesives, the enterprises should focus on research and development of this large number of applications and the West has a huge number of potential applications tech hot melt adhesive products, including: reactive hot melt adhesives, water-dispersible hot melt adhesive, hot melt rubber lined tablets and high-end PA HMPSA high strength and so on. While the domestic manufacturers of raw materials should also be relevant to understanding the development potential of hot melt adhesive industry, to accelerate improvements in the localization rate of raw materials and reduce the loss of foreign exchange due to massive imports of raw materials caused. 
    The new hot melt adhesive for improvements, nor can be completed overnight, technological advances, product of any kind will be replaced by new products. Before new products stable, traditional hot melt adhesive products still account for a large market.
