What is DOTP (Dioctyl Terephthalate)?
DOTP is a non-phthalate plasticizer that serves as a drop-in replacement for DOP in most PVC applications. It offers similar performance with improved regulatory compliance.
How it works
Same mechanism as DOP — reduces intermolecular forces in PVC chains — but with a terephthalate ester backbone instead of phthalate.
Applications
- PVC cables (REACH compliant)
- Toys and childcare articles
- Food contact packaging
- Medical devices
- Flooring
- Automotive interiors
Advantages
- +Phthalate-free — no regulatory issues
- +Drop-in replacement for DOP
- +Lower migration than DOP
- +Growing availability in India
Limitations
- −10-15% more expensive than DOP
- −Slightly lower efficiency at very high loadings
