As a hot melt adhesive machine manufacturer, we know that hot melt adhesive is solvent-free thermoplastic material, which can use at a temperature between 120 ° C to 180C in a molten state mixed.
The hot melt adhesive composition mainly consists of three parts,first,it's a high molecular weight polymers (such as EVA or synthetic rubber),which is equivalent pillar for hot melt glue adhesive,the adhesive provides the main mechanical properties. Second,it's a tackifying resin, which provides wetting and bonding properties, Thirdly, it's a plasticizers,such as oils or waxes,to control the viscosity of the mixture,and ensure to the binder by a simple mechanical treatment.
In addition, hot helt adhesive is widely used in packaging, product assembly,imber processing and pressure sensitive tapes and labels etc.
