Dioctyl Terephthalate (DOTP) CAS 6422-86-2

Dioctyl Terephthalate (DOTP) is supplied as a general-purpose plasticizer for PVC and other polymer systems, positioned as a non-phthalate alternative to traditional ortho-phthalate plasticizers. It is commonly used in flexible PVC formulations where processability, compatibility, and balanced mechanical properties are required.

Typical downstream applications include wire and cable compounds, films and sheets, synthetic leather, and coated fabrics. DOTP is generally supplied in liquid form suitable for direct use in industrial compounding processes. Standard export packaging, bulk supply, and technical documentation such as COA, TDS, and SDS are available to support procurement and formulation work.

  • Flexible PVC products such as films, sheets, and flooring materials
  • Synthetic leather and coated fabric formulations
  • Polymer processing where non-phthalate plasticizers are preferred for regulatory or formulation considerations

Packaging

DOTP is supplied as a liquid ester and is typically packed in clean, sealed drums, IBC containers, or bulk liquid systems suitable for industrial handling. Packaging is selected based on transport conditions and order volume to ensure product integrity during storage and shipment. Containers are handled to minimize contamination and maintain consistent quality throughout the supply chain.

Storage

Store in a cool, dry, and well-ventilated area in tightly closed original containers. Avoid prolonged exposure to direct sunlight and sources of heat. Properly sealed packaging should be maintained during storage and transportation to prevent contamination and preserve product stability.
