Import Dinp (Diisononyl Phthalate) — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

Dinp (diisononyl phthalate) from Crovell Co., Ltd. is a high-purity plasticizer with a CAS number of 28553-12-0, designed for use in rigid and flexible PVC formulations. The product exhibits a density of approximately 0.98 g/cm³ at 20°C and a viscosity range of 180 to 220 cP at 40°C, as stated in the listing. Its molecular weight is 390.5 g/mol, and it is formulated to meet the requirements of industrial-grade plasticization where long-term flexibility and low volatility are critical.

This material is typically used as a replacement for DOP in applications requiring reduced migration and improved thermal stability. The product is manufactured to contain less than 0.05% free phthalic acid and has a color value of less than 10 Hazen units, indicating minimal impurity content. In industry practice, DINP grades are commonly classified under ASTM D1566 and ISO 16899, with standard purity levels ranging from 98% to 99.5%. The low volatility rate, confirmed by a loss on drying test under 0.1% at 105°C for 1 hour, ensures extended product lifespan in end-use items.

End users include manufacturers of automotive interiors, wire and cable insulation, synthetic leather, and flexible PVC films. Buyers in the construction and consumer electronics sectors commonly source this material for its electrical insulation properties and resistance to extraction by oils and solvents. Packaging is typically in 200 kg steel drums or 1000 kg IBC totes. Trade terms are negotiable but generally follow FOB Seoul or CIF terms. MOQ and lead time must be confirmed directly with the supplier as they are not specified in the listing.
