Key Differences from DOP and DOTP

Discover the essential differences between DOP (Dioctyl Phthalate) and DOTP (Dioctyl Terephthalate), two popular plasticizers used in PVC plastics. Both are colorless, oily liquids with similar molecular structures and weights, but their unique properties set them apart:

1. Plasticizing Efficiency: DOP offers slightly higher plasticizing efficiency, providing broader applicability across various uses.

2. Electrical Performance: DOTP excels in electrical performance, boasting 20 times the volume resistivity of DOP. Ideal for electrical applications.

3. Heat Resistance: With a flash point 10°C higher than DOP, DOTP ensures stable electrical performance after heating and has half the residual volatile content, perfect for high-temperature PVC cable materials.

4. Cost: While DOTP is marginally more expensive, its benefits often justify the cost.

5. Cold Resistance: DOTP significantly outperforms DOP in cold resistance, making it the preferred choice for automotive, refrigerator, and window sealing strips, offering cost-effective solutions.

6. Environmental Safety: DOP exposure can cause health issues, including respiratory and central nervous system problems, and is heavily regulated in Europe and the US. DOTP, fully compliant with EU RoHS and US SGS standards, provides a safer alternative.
