- Medical Plastics: Ideal for medical devices, IV bags, syringes, and blood storage containers.
Why Choose DOTP Over Traditional Plasticizers?
When compared to dioctyl phthalate (DOP) and other conventional phthalates, DOTP, Dioctyl Terephthalate offers several advantages:
- Higher Heat Resistance – Maintains stability at elevated temperatures.
- Improved Cold Resistance – Performs efficiently under low temperatures.
- Better Electrical Insulation – Ideal for high-voltage cable applications.
- Low Volatility – Reduces emissions and improves durability.
- Superior Resistance to Extraction – More resistant to external substances like soapy water and solvents.
- Minimal Migration – Prevents plasticizer leaching, ensuring long-term performance.
Versatile Industrial Uses of DOTP
DOTP, Dioctyl Terephthalate has excellent plasticizing effects with low volatility, making it a preferred choice in:
- Medical and Food Packaging: Safe for use in pharmaceutical packaging, food wrap films, and disposable syringes.
- Rubber and Synthetic Applications: Enhances flexibility and chemical resistance in rubber products, artificial leather, and nitrile rubber.
- Paint and Coating Additives: Functions as a plasticizer in precision instrument lubricants, nitro varnishes, and interior decoration coatings.
- High-Quality Lubricants: Used in synthetic lubricant additives and specialty coatings.
DOTP for Electrical Cables – A Superior Choice
Manufacturers widely use DOTP, Dioctyl Terephthalate in electrical cables due to its high thermal stability and flame resistance, particularly for 70°C temperature-resistant materials that comply with IEC (International Electrotechnical Commission) standards. Its low volatility and excellent insulation properties make it the best choice for long-lasting, high-performance wiring solutions.
