Di-N-Octyl Phthalate

Di-N-Octyl Phthalate (DNOP) — Chemical name: Di-n-octyl phthalate. CAS: 117-84-0. DNOP is a colorless to pale-yellow oily liquid with low water solubility and good compatibility with many resins. It is used as a conventional phthalate plasticizer that provides balanced plasticizing performance, low volatility and good processing stability.

Performance Advantages

Balanced plasticizing efficiency — imparts softness and flexibility to PVC and many polymer matrices.
Low volatility & good thermal stability — reduces plasticizer loss during processing and service.
Excellent compatibility with PVC, nitrocellulose and other common resins.
Stable processing behavior — suitable for extrusion, calendaring and coating applications.

Typical Applications

Wire & cable insulation and sheathing — flexible compounds for general wiring and building cable.
Flooring, vinyl sheets & films — improves flexibility and wear properties.
Synthetic leather & coated fabrics — upholstery, automotive trim and leatherette.
Medical tubing & components (where permitted and compliant with local regulations).
General PVC items: hoses, seals, profiles and sealants.

Packaging, Supply & Logistics

Standard packing: 200 kg drums, 900 kg IBCs; flexibag or bulk orders by arrangement.
Storage: keep in a cool (2–8 °C recommended for long-term), well-ventilated place away from strong oxidizers and heat sources.

Safety & Environmental Notes

DNOP is combustible at high temperature—handle with appropriate PPE and avoid release to the environment. Note: some end-uses (toys, childcare articles, food contact) may be subject to regulatory limits in specific markets — buyers should confirm compliance for intended applications.
