List of Removable Types for Hot Melt Adhesive Particles: 3 Scenarios and Corresponding Models Quick Check

When does it need to be detachablehot melt adhesive pellets？

Some application scenarios require non-destructive disassembly after bonding, such as fixing the inner lining of gift boxes, bonding sample display cards, temporary positioning assembly, etc. Ordinary hot melt adhesive particles can damage the material when peeled off after curing, while detachable adhesive particles have a special balance between adhesion and separability.

3 types of detachable scenarios and selection list

• 1. Fixed inner lining of gift box (low adhesive and removable type)
  Requirement: Stick the inner lining to prevent transportation displacement, and the user can easily remove it without leaving any residue when unpacking the box
  Recommendation: Pressure sensitive low viscosity hot melt adhesive particles, with a peeling force of 0.5-1.0N/cm, and no residue after peeling off
• 2. Sample display card/hang tag (medium adhesive positioning type)
  Requirement: During the exhibition, it should be firmly adhered and not moved. When the exhibition is removed, the entire piece can be peeled off
  Recommendation: Modified EVA medium viscosity adhesive particles with a peeling force of 1.5-2.5N/cm, and residual adhesive can be rubbed off after peeling off
• 3. Temporary assembly positioning (high viscosity, heat detachable type)
  Requirement: The assembly process should be firmly positioned, and the subsequent heating should be separable
  Recommendation: Low softening point EVA adhesive particles, can be softened and separated by heating at 60-70 ° C, with a peeling force of 3-4N/cm

Selection Attention

Detachable ≠ Non stick – the key is “able to stick, remove, and leave no residue”. The Sunlife hot melt adhesive detachable series covers the above three levels of adhesion, and Guangzhou Sunlife Trading provides free comparison samples with a starting weight of 1kg.

Frequently Asked Questions

• Q: How long can the adhesive force of detachable rubber particles last?
  A: The low viscosity type takes about 3-6 months, the medium viscosity type takes about 12 months, and the high viscosity type is equivalent to ordinary adhesive particles, but can be separated by heating.
• Q: How to clean any residual glue after uncovering?
  A: Low viscosity type generally has no residue; Medium adhesive residue can be rubbed off with fingers or lightly wiped with alcohol; High viscosity type needs to be wiped off after heating at 60 ° C.
