What is driving the shift from DOP to DINP in the Chinese plasticizer market?

The INA feedstock gap is the real bottleneck. With Qixiang Tengda's 200,000 t/y project still ramping, expect import dependency to persist through 2025. Buyers should watch INA spot prices as a leading indicator for DINP contract negotiations.

How does DINP compare with DOP in performance for PVC applications?

That 10% efficiency penalty matters more in thin-film applications where cost per unit softness is critical. For wire and cable, though, the thermal stability advantage justifies the premium. Always check the end-use temperature spec before substituting.

What are the key technical specifications and safety data for DINP buyers?

The LD50 data is reassuring, but don't overlook the regulatory angle. Even though DINP is 'safer' than DOP, it still faces restrictions in toys and childcare articles. If your downstream is in those sectors, consider DINCH or citrates instead.

Overview

Dinonyl phthalate (DNP, CAS 84-76-4) is a colorless, oily liquid with a density of 0.98 g/mL at 20°C, a melting point of -33.15°C, and a boiling point of 279-287°C. It is a high-molecular-weight plasticizer used primarily to impart flexibility and durability to polyvinyl chloride (PVC) and other polymers.

Industrial: serves as a general-purpose plasticizer for PVC, improving flexibility, low-temperature performance, and resistance to heat and extraction.
Cables & wiring: provides good electrical insulation properties, making it suitable for wire and cable jacketing.
Automotive: used in interior films, sealants, and underbody coatings where durability and weatherability are required.
Consumer goods: found in flooring, wall coverings, and synthetic leather products.

China's production landscape for dinonyl phthalate is shaped by feedstock availability, primarily nonyl alcohol and phthalic anhydride. The market is competitive, with a mix of large integrated producers and smaller regional players. Recent regulatory scrutiny on phthalate migration in food-contact materials is pushing producers toward higher-purity grades and alternative plasticizers.

Key domestic producers:
Shandong Hongxin – large-scale plasticizer manufacturer.
Wuxi Liangjiang – diversified plasticizer and chemical producer.
Zhejiang Jianye Chemical – specialty plasticizers and fine chemicals.
