DOTP vs DINP vs DOP — Technical Comparison
DOTP vs DINP vs DOP — Technical Comparison
DOTP, DINP and DOP are among the most widely used plasticizers in the PVC industry. Each has distinct performance characteristics, migration behavior and regulatory implications.
1. DOTP
Non-phthalate
REACH & RoHS compliant
Low migration, low odor
Excellent heat stability
Ideal for cables, hoses, footwear and compounds
2. DINP
Widely used phthalate
Strong mechanical properties
Moderate migration
Restricted in toys and childcare articles
3. DOP (DEHP)
Classified as SVHC
Restricted in EU
High migration and odor
Low-cost but non-compliant for exports
4. Performance Comparison Table
| Property | DOTP | DINP | DOP |
|---|---|---|---|
| Regulatory compliance | Excellent | Moderate | Poor |
| Migration | Very low | Medium | High |
| Odor | Very low | Medium | High |
| Mechanical strength | High | Very high | Moderate |
| Long-term stability | Excellent | Good | Weak |
Conclusion
DOTP is the most future-proof, export-compliant and environmentally responsible choice for modern PVC applications.
