General-Purpose Plasticizer for Flexible PVC
Diisononyl Phthalate DINP is a high-molecular-weight general-purpose plasticizer mainly used in flexible PVC and related polymer systems. Its molecular formula is C26H42O4, and its CAS number is 28553-12-0. The product is supplied as a transparent, low-color oily liquid with an ester content of at least 99.5%.
DINP helps improve the flexibility and processing performance of PVC materials. It also offers relatively low volatility loss and good plasticizer retention. These properties make it suitable for PVC formulations that need stable processing performance together with long-term flexibility and aging resistance.
Applications in Flexible PVC Products
- DINP can be used in a wide range of flexible PVC products, including wires and cables, artificial leather and synthetic leather, PVC flooring, PVC films and sheets, wallpaper, and coated fabrics.
- Compared with some traditional general-purpose plasticizers, it provides a balanced combination of volatility control, migration stability, aging resistance, and long-term flexibility. This makes it especially useful for PVC products that need to remain soft during extended use.
- For manufacturers of artificial leather, films, flooring, cable compounds, and other flexible PVC products, Diisononyl Phthalate DINP provides a broad formulation range. Its stable plasticizing performance allows manufacturers to adjust formulations according to different processing conditions and end-product requirements.
Quality Control and Supply Support
Jiaxing Xiaolan Import and Export Co., Ltd. focuses on the supply chain of plasticizers and chemical raw materials. Its product range covers plasticizers, PVC resin, PVC additives, and related acid and alcohol raw materials.
The company works with large chemical manufacturers in China. Team members with chemical industry experience participate in supplier coordination, quality follow-up, and order execution. Quality control and logistics personnel can follow production progress, batch sampling, packaging, and delivery at the factory side. This helps keep the order process clear from specification confirmation through shipment.
Each batch can be supplied with a COA analysis report and MSDS. If additional inspection is required, SGS, BV, or other third-party inspection arrangements can also be supported according to the purchasing project.
Packaging and Purchasing Options
- DINP can be supplied in several packaging formats to match different storage, transportation, and production requirements. Available options include 200L iron drums with a net weight of approximately 200 kg per drum, IBC tanks of approximately 1000 kg, ISO tank bulk shipment, and flexitank shipment.
- Customers can select drum, IBC, or bulk supply according to actual consumption, warehouse conditions, transportation methods, and feeding requirements. Flexible repacking requirements can also be discussed.
- For continuous production, bulk purchasing, or projects involving several PVC raw materials, the combination of product specification confirmation, batch quality documents, packaging selection, factory-side quality follow-up, and logistics coordination provides a clearer and more manageable purchasing process.
