Dioctyl terephthalate DOTP

Product Overview

Dioctyl Terephthalate (DOTP) — chemical name Di(2-ethylhexyl) terephthalate, CAS 6422-86-2 — is a colorless to slightly yellow oily liquid used as a primary plasticizer in PVC and other polymer applications. DOTP delivers a mix of high-temperature stability, low migration/volatility and good low-temperature flexibility, making it an excellent non-phthalate alternative to traditional phthalate plasticizers in cables, flexible PVC, artificial leather and specialty formulations.

Performance Advantages

High heat resistance & thermal stability — suitable for wire & cable formulations and other high-temperature applications.
Low volatility & migration — improves long-term flexibility and reduces plasticizer loss vs many alternatives.
Excellent extraction and soap-water resistance — ideal for products exposed to oils, detergents or outdoor conditions.
Good electrical insulation properties — preferred for PVC electrical cable insulation meeting IEC 70 °C and similar specs.
Broad compatibility — works well in PVC, acrylonitrile derivatives, nitrile rubbers, nitrocellulose and specialty polymer systems.

Typical Applications

1. PVC cables & wiring insulation (heat-resistant cable compounds).
2. Flexible PVC products: hoses, profiles, sealants, gaskets and films.
3. Artificial leather / PVC leather films & synthetic leather production.
4. Specialty polymer formulations where low migration and long durability are required (e.g., nitrile rubber, PVB, nitrocellulose).
5. Additive uses: lubricant additives, processing aids and specialty coatings.

Packaging, Supply & Commercial Information

Standard packing: 200 kg drums, 900 kg IBC, flexibag; bulk orders possible.
Purposes: sample orders available (customer pays courier); bulk / contract supply for OEMs.
Trade & export: stable global supply network and pre-shipment COA sharing.

Safety & Storage

Store in a cool, dry place (recommended 2–8 °C for long term storage). Avoid exposure to strong oxidizers and high temperatures. Handle concentrated product with suitable PPE (gloves, goggles); DOTP is generally stable under normal industrial use; follow local regulatory guidance for use in consumer or food-contact applications.
