Dioctyl phthalate

Dioctyl phthalate (CAS 117-84-0 ), commonly abbreviated as DNOP, is a primary plasticizer used to impart flexibility and durability to PVC and other polymer systems. It functions by reducing the glass transition temperature of the base resin. This chemical enables processors to achieve targeted softness and elongation in finished materials. DNOP is used in flexible PVC compounding for wire and cable insulation, flooring, and industrial sheeting where low volatility is required. It is particularly valued for applications needing good electrical properties. In coatings and sealants, it acts as a plasticizing modifier to control film flexibility and adhesion across a range of various industrial substrates. Personal care formulators have incorporated it as a film-forming plasticizer in nail lacquers, though regulatory pressure has driven reformulation in many markets. It also appears in adhesive formulations for viscosity control. Controlled softness and processing viscosity are critical to end-product performance in these sectors. DNOP is supplied as a clear, oily liquid in bulk quantities, typically in ISO tank containers, drums, and IBCs. Technical grade is the standard commercial offering, with purity specifications generally at 99% or above. Buyers should verify current regulatory compliance requirements for their target market before sourcing materials. Restrictions vary by region and application, making due diligence essential for procurement. This material remains a staple in the polymer industry for its reliable performance and consistent chemical properties. Contact us for supply of Dioctyl phthalate Request Quote
