Which is characterized by excellent thermal stability, solvent-free, no impurities, good maneuverability, excellent weather resistance, defects are obviously affected by temperature viscosity. It smear in a molten state, applying a slight finger pressure and cooled to solidify can play a role in the adhesion. Its wide range of applications, can be used for all kinds of sealing, seal boxes, paper packaging, beverage bottle labels, sealing foil, flexible packaging and other packaging, double-sided tape, labels, health, magic, wallpaper and footwear etc., which HMPSA largest consumer packaging, accounting for almost half of the total.
