Advanced Hot Melt Glue for Durable and Heat-Resistant Bonding

Industrial hot melt glue is a thermoplastic bonding material widely used across packaging, automotive, construction, hygiene, textiles, and electronics. It is classified by chemical composition, each with distinct performance characteristics and application areas.

• EVA (Ethylene-Vinyl Acetate)
  • Features: Good adhesion, flexibility, and cold resistance; limited strength; poor heat and oil resistance.
  • Applications: Bookbinding, woodworking, carton sealing, shoemaking, furniture edging.
• Polyolefin (PE/PP)
  • Features: Non-toxic, chemical-resistant, low water absorption; suitable for porous materials but slower setting.
  • Applications: Food packaging, non-woven laminating, automotive carpets, box sealing.
• Polyester (PET/PES)
  • Features: High strength, impact- and heat-resistant (up to 150 °C), excellent insulation; requires specialized equipment due to high viscosity.
  • Applications: Garment interlining, electronic parts fixing, automotive interiors, construction surfaces.
• Polyurethane (PUR/TPU)
  • TPU: Elastic, strong, efficient for high-speed production.
  • PUR: Moisture-curing, highly durable, heat- and water-resistant (up to 180 °C).
  • Applications: Automotive wiring, structural bonding, premium furniture edging.
• Styrenic Block Copolymers (SBS/SIS)
  • Features: Elastic, good low-temperature performance; SIS has low viscosity, suitable for precise coating.
  • Applications: Hygiene products, pressure-sensitive labels, automotive interiors.
• Polyamide (PA)
  • Features: High strength, resistant to heat, oil, and chemicals.
  • Applications: Automotive engine parts, electronic encapsulation, footwear bonding.

• Packaging: EVA and polyolefin dominate box and food packaging, ensuring fast curing.
• Automotive: PUR and PA used for interior bonding, wiring, and heat-/oil-resistant parts.
• Furniture & construction: EVA and PUR applied in MDF/PVC edge banding and structural adhesion.
• Hygiene & textiles: SBS/SIS for diapers and sanitary products; EVA for garment interlinings.
• Electronics:Polyester and polyamide for insulation and component encapsulation.

• Softening point: Determines heat resistance (automotive glue requires > 100 °C).
• Viscosity: Affects coating efficiency (low viscosity enables precise spraying).
• Open time: PUR provides longer assembly time; EVA sets within seconds.
• Environmental safety: 100% solid, solvent-free, compliant with food and medical standards.

The hot melt glue industry is moving toward higher performance and eco-friendly solutions, highlighted by heat-resistant PUR grades, gentle medical formulations, and lightweight options for EV applications.
