Dioctyl Terephthalate (DOTP)
DOTP High-Performance Plasticizer
Molecular Formula
C₂₄H₃₈O₄
DOTP is a high-performance main plasticizer engineered for superior electrical and thermal properties. With a volume resistivity 10-20 times higher than traditional DOP, it is the ideal choice for demanding cable material applications.
Key Advantages
- Superior Electrical Performance: High volume resistivity for enhanced insulation
- Excellent Durability: Exceptional resistance to heat, cold, and extraction
- Low Volatility: Maintains stability under varying temperature conditions
- Processing Efficiency: High growth rate and excellent soap water resistance
Applications
Widely used in cable materials, insulation skins, advanced paints, coatings, and other products requiring heat resistance and high insulation.
