Bulk Wholesale Dioctyl Terephthalate DOTP Non-Phthalate Plasticizer Low Price
Product Overview
Dioctyl Terephthalate (DOTP)
CAS Number: 6422-86-2
Molecular Formula: C₂₄H₃₈O₄
Molecular Weight: 390.56
Dioctyl Terephthalate (DOTP) acts as a high-performance main plasticizer that is professionally engineered to possess exceptional electrical performance and reliable thermal resistance. In comparison with traditional DOP, its volume resistivity reaches 10-20 times higher, effectively improving the insulation capability of PVC compounds. This unique advantage makes DOTP the perfect high-grade plasticizer for all industrial scenarios that require strict insulation standards, especially demanding wire and cable material applications.
Key Advantages
- High plasticizing efficiency
- Wide resin compatibility
- Good low-temperature toughness
- Stable anti-migration property
- Compatible with rubber vulcanization
- Cost-efficient industrial plasticizer
Applications & Performance
- Widely used in cable materials, insulation skins, advanced paints, and coatings
- Ideal plasticizer for temperature resistant 70℃ cable materials and PVC products requiring volatility resistance
- Excellent cold resistance, heat resistance, extraction resistance, and volatility resistance
- Can be mixed with DOP in any proportion
- Reduces viscosity and increases storage life when used in plasticized paste
