What is Dioctyl Terephthalate (DOTP) CAS 6422-86-2 used for?

DOTP is a high-boiling ester plasticizer used mainly in flexible PVC and other polymer systems. Typical applications include wire and cable compounds, films, sheets, flooring, synthetic leather, and coated fabrics.

Is DOTP a non-phthalate alternative to traditional plasticizers?

Yes. DOTP is bis(2-ethylhexyl) terephthalate, a terephthalate ester rather than an ortho-phthalate. It is commonly used as a non-ortho-phthalate alternative in PVC formulations, but specific compatibility and performance should be evaluated in the target compound.

What are the key performance properties of DOTP in PVC?

It provides good flexibility, low volatility, high compatibility with PVC, and suitable electrical properties. Its high flash point and low water solubility also support use in cable insulation, sheathing, and durable flexible products.

How is industrial-grade DOTP normally supplied?

It is supplied as a liquid ester in standard industrial packaging such as drums, IBC containers, or bulk liquid systems. Packaging and transport arrangements are selected according to order volume and logistics requirements.

How should DOTP be stored?

Keep it in tightly closed original containers in a cool, dry, well-ventilated area. Avoid prolonged exposure to direct sunlight and heat sources, and keep the packaging sealed during storage and transport to prevent contamination.
