Its stability under UV exposure and low volatility ensure long-lasting performance in cables, artificial leather, and films.
Reliable Storage and TransportPackaged in robust steel drums or ISO tanks, DOTP is classified as non-hazardous under transport regulations. It remains stable under normal storage, ensuring consistent quality for up to one year when kept in a cool, dry, and ventilated space away from sunlight.
FAQs of Dioctyl terephthalate (DOTP):
Q: How is Dioctyl terephthalate (DOTP) typically used in industrial applications?
A: DOTP is widely added to PVC resins and polymer blends as a plasticizer to enhance flexibility, durability, and processability. Common applications include cables, flooring, artificial leather, toys, and polymer films.
Q: What benefits does DOTP offer compared to conventional phthalate plasticizers like DOP?
A: DOTP provides a comparable plasticizer efficiency to DOP but offers greater environmental safety, lower toxicity, improved UV resistance, and better overall stability, making it preferable for sensitive applications.
Q: When should DOTP be chosen for manufacturing polymer products?
A: DOTP should be selected when environmental considerations, low volatility, and excellent UV stability are priorities, especially for products like toys, flooring, and cables where safety and longevity are required.
Q: Where is DOTP most effectively stored to ensure optimal shelf life?
A: DOTP is best stored in a cool, dry, well-ventilated area, away from direct sunlight and ignition sources. Under these conditions, DOTP remains stable and maintains its quality for at least one year.
Q: What is the process for applying DOTP as a plasticizer in PVC formulations?
A: DOTP is typically mixed directly with PVC resins or plastisols during compounding. Its liquid form and excellent solubility in organic solvents ensure smooth integration and dispersion, resulting in uniform flexible products.
Q: How does DOTP benefit electrical cable production?
A: DOTPs good electrical properties, low volatility, and high thermal stability make it ideal for flexible cable insulation, reducing risks of degradation and maintaining performance over prolonged use.
Q: Is DOTP compliant with current environmental and safety regulations for import/export?
A: Yes, DOTP conforms to international plasticizer specifications and is considered non-hazardous under transport regulations, ensuring easy distribution by importers, exporters, and suppliers worldwide.
