As international regulatory frameworks continuously tighten around chemical safety, the demand for clean, compliant raw materials is reshaping modern manufacturing. Plasticizer DOTP (Dioctyl terephthalate) stands at the forefront of this green transition. Chemically categorized under CAS No. 6422-86-2, DOTP is a structural isomer of DEHP (DOP) but is classified as a non-ortho-phthalate (terephthalate). This crucial chemical divergence frees it from the stringent restrictions placed on traditional phthalates while delivering matching plasticizing efficiency, excellent electrical insulation, and superior low-temperature performance.

Why Choose Our DOTP Plasticizer?
- ✓ Seamless Regulatory Compliance: Free of restricted ortho-phthalates. It smoothly satisfies eco-friendly requirements including EU REACH, RoHS, and California Proposition 65.
- ✓ Excellent Cold & Heat Resistance: Exhibits lower volatility at processing temperatures and better low-temperature flexibility than DOP, extending the compound’s performance window.
- ✓ High Volume Resistivity: Delivers electrical properties that outclass standard plasticizers, making it highly valued for high-temperature PVC cable formulations.
Primary Applications
DOTP is widely applied where health safety, environmental certification, and long-term material stability are strictly required:
Consumer & Medical Products
An ideal choice for eco-conscious toys, children’s products, specialized medical tubing, food packaging films, and household vinyl items.
High-Spec Wires & Cables
Extensively formulated into heat-resistant electrical wire jacket sheets (such as 70°C cable compounds) requiring lasting insulation and low extraction.
Plastisols, Inks & Coatings
Provides low initial viscosity and superior shelf-life viscosity stability for wallpaper pastes, fabric coatings, and high-quality screen-printing inks.
Quality Assurance & Global Compliance
As a leading international supplier, we ensure strict monitoring of all raw materials to safeguard your batch consistency. Our chemical refining complexes work under precise manufacturing protocols to meet rigorous global standards and support seamless customs entry:
- Advanced Analytical Quality Control: Every distribution batch of our DOTP liquid undergoes exhaustive validation—including high-resolution gas chromatography (GC) purity verification, color matching checks, and rigorous moisture controls—to preserve absolute structural properties.
- Comprehensive Document Support: Our eco-friendly material is fully backed by up-to-date tracking documentation, including multilingual GHS Safety Data Sheets (SDS), technical datasheets, Certificates of Analysis (CoA), and regulatory confirmations fully matching EU REACH and US TSCA parameters.
- Flexible Bulk Logistics: We provide diverse logistics delivery choices to match your factory setup, supplying raw material through stainless steel ISO tank containers, intermediate bulk containers (IBC drums, 1000kg), and standard steel drums (200kg) packed with nitrogen padding to block moisture.
⚠ Storage & Handling Guidelines
Maintaining correct warehouse controls ensures that the ester purity of your DOTP liquid remains locked over long storage durations. Proper moisture exclusion is the primary safeguard against slow acid value increases or hydrolytic reactions.
- • Shaded Warehousing: Keep containers stored inside a cool, dry, and well-ventilated enclosure. Ensure the material lines remain completely isolated from strong oxidizing chemical compounds, open spark risks, and direct high-heat conduits.
- • Seal Maintenance: Reseal bung caps and container flanges securely immediately after fluid dispensing to prevent atmospheric humidity and moisture from entering the drum head space and triggering ester degradation.
- • Inventory Shelf Life: Under appropriate, original sealed storage parameters, our premium DOTP holds a certified shelf life of 24 months from the manufacture date. Following a strict First-In, First-Out (FIFO) material distribution pattern is highly advised.
