Hot melt glue is a solvent-free thermoplastic adhesive that can be repeatedly melted and bonded by heating to melt and cooling to solidify.
| Component | Function | Example |
| Resin (main polymer) | Provides adhesion and mechanical properties | EVA, SBC (SIS, SBS), TPR, Polyamide (PA), Polyolefin (PO), Polyurethane (PU) |
| Tackifier | Improves initial tack and bond strength | Rosin resin, Terpene resin, C5/C9 petroleum resin, Hydrogenated petroleum resin |
| Wax | Controls melt viscosity, adjusts open time and curing speed | Microcrystalline wax, Polyethylene wax, Synthetic wax, Fischer-tropsch wax |
| Antioxidant | Prevents heat aging and yellowing | 1010,168, 1076, etc. |
| Filler (optional) | Reduces costs or adjusts viscosity | Talc, Calcium carbonate, Silica |

| Application scenatio | Typical substrate | Formula Type |
| Carton sealing and packaging | Paper, paperboard | EVA/PO hot melt glue |
| Labels and self-adhesive labels | Paper, PET, PE | SIS/SBS pressure sensitive adhesive |
| Furniture edge sealing | Wood, PVC | PUR hot melt glue |
| Electronic component packaging | Metal, plastic | PA hot melt glue |
| Hygiene products | Non-woven fabric, PE film | SIS hot melt pressure sensitive adhesive |
