1. DOTP (Dioctyl Terephthalate)
Features
Non-phthalate → reach and RoHS compatible
Low migration
Excellent temperature stability
Ideal for the production of cables, hoses, shoes, granules
Advantages
✔ High performance
✔
Low odor
Fully compliant with the✔ European market
2. DINP (Di-Isononyl Phthalate)
Features
Medium migration
High mechanical resistance
Extremely wide range of applications
Limited use in toys (EU)
DOP 3 (DEHP)
Features
Toxicologically risky
SVHC in the list of
Prohibited / Restricted in many sectors
Low cost but export incompatible
4. Performance Comparison
| Feature | DOTP | DINP | DOP |
|---|---|---|---|
| Compliance | ★★★★★ | ★★★★ | ★ |
| Migration | ★★★★★ | ★★★ | ★★ |
| Odour | A lot low | Medium | High |
| Mechanical performance | High | Very high | Medium |
| Regulatory compliance | Full | Partially | Low |
Conclusion
For long-term and export-oriented manufacturers, DOTP is → the safest and most sustainable choice.
