Which Hot Melt Chemistry Fits Your Application?
Answer 3 questions to see whether PES (copolyester), TPU, or EVA hot melt film best matches your bonding requirement — based on Teng Yang’s chemistry comparison data (dry-cleaning resistance, post-wash flexibility, relative cost).
1. Does the finished product need to survive dry-cleaning solvents?
2. Will it undergo frequent washing after bonding?
3. What matters more for this order?
| Property | PES | TPU | EVA |
|---|---|---|---|
| Dry-cleaning solvent resistance | High | Moderate | Low |
| Post-wash flexibility retention | High | High | Moderate |
| Relative material cost | Higher | Highest | Lowest |
Based on Teng Yang’s published chemistry comparison (see Performance Comparison table above). Peel/shear performance is substrate- and process-specific per ASTM D1002 — confirm with a technical data sheet and sample test before finalizing chemistry.
