Dioctyl terephthalate, commonly known as DOTP, is a non-phthalate plasticizer with the CAS number 6422-86-2 and molecular formula C24H38O4. It has a molecular mass of 390.5 g/mol and meets the following verified specifications: color ≤30 Hazen, acid value ≤0.07 mgKOH/g, density between 0.981 and 0.985 g/cm³ at 20°C, water content ≤0.1 wt%, flash point ≥210°C, and ester content ≥99.0% by GC. These values are measured using standardized Chinese national methods GB/T 1664, GB/T 1668, GB/T 4472, GB 11133, and GB 1671.
DOTP is chemically distinct from traditional phthalates like DOP, offering superior thermal and electrical insulation properties. Its volume resistivity is ten to twenty times higher than DOP, making it ideal for high-performance PVC applications requiring low volatility and long-term stability. The compound exhibits excellent cold resistance, extraction resistance, and plasticizing efficiency, with low migration rates in finished products. It is typically used in applications demanding durability under heat and moisture, such as cable insulation and medical-grade PVC films.
This product is primarily purchased by manufacturers of 70°C-rated electrical cables, high-grade PVC gloves, artificial leather, and protective coatings. It can be blended freely with DOP to adjust flexibility and processing characteristics. Buyers typically source it in 200kg drums or 1000kg IBC totes. Lead time for bulk orders is confirmed directly with the supplier, and shipping terms are negotiable under FOB or CIF conditions from ports in Shandong Province.

Before placing an order, verify the batch-specific test reports for ester content, acid value, and water content. Request a copy of the GC chromatogram and confirm that the product meets GB/T standards as listed. Do not accept generic certificates; demand data tied to the shipment’s production batch. Also confirm the packaging type - drums or IBCs - and ensure containers are clean, dry, and labeled with the chemical name and CAS number.
Logistics are typically handled via FOB Qingdao or Shanghai ports. Lead time for bulk orders ranges from 10 to 20 days after payment confirmation, depending on production scheduling. Incoterms should be clearly defined: FOB is most common, but CIF is negotiable. Payment terms are usually T/T in advance or L/C at sight. Confirm with the supplier whether the shipment includes a commercial invoice, packing list, and bill of lading with full HS code details.
Upon arrival, conduct a visual inspection for container integrity and label accuracy. Sample the product using a clean, dry probe and test for viscosity, density, and water content using ASTM or GB methods. Retain a sample for 30 days in case of quality disputes. Request a certificate of analysis with each shipment, and ensure it includes the date of manufacture, batch number, and the signature of the quality control officer.
