Film-Grade PES Hot Melt Adhesive Granules for Heat Transfer Film Production
Hot melt adhesive (HMA) granules are small, solid pellets made from thermoplastic polymers that melt when heated and solidify upon cooling to form a strong bond between surfaces. They are a solvent-free, fast-curing adhesive widely used in industrial and consumer applications.
Typical Processing Conditions
Pressing temperature: 130°C - 150°C
Pressure: 1.0 - 3.0 MPa
Time: 10 - 15 seconds
Cooling: 5 - 10 seconds on a cold press table to stabilize bonding
(Actual parameters should be adjusted according to fabric and equipment)
Key Characteristics
Thermoplastic: Can be repeatedly melted and solidified without chemical changes
Solvent-free: Eco-friendly, with low or no VOC emissions
Fast-setting: Bonds quickly once melted and cooled
Versatile: Can bond metals, plastics, textiles, wood, and more
Easy to handle: Granular form allows precise dosing and automated feeding in production lines
Applications
Packaging (e.g., carton sealing, can bonding)
Automotive components
Textiles and footwear
Electronics assembly
Powder coating and lamination processes
Frequently Asked Questions
What is the shelf life?
12 months.
Why are they called "film-grade"?
"Film-grade" refers to the resin's ultra-low impurity levels, consistent molecular weight distribution, and optimized viscosity, all of which are critical for producing defect-free films or membranes with uniform pore structures and stable performance.
