Di-Isononyl-cyclohexane-1,2-dicarboxylate, commonly known as DINCH (CAS No.: 166412-78-8), stands as a modern, high-performance plasticizer, representing a significant advancement in material science. As industries increasingly prioritize safety and environmental responsibility, DINCH offers a compelling alternative to traditional phthalate-based plasticizers, providing enhanced flexibility and durability across a vast array of polymer applications.

Chemically, DINCH is recognized by several synonyms, including Bis(2-ethylhexyl) cyclohexane-1,2-dicarboxylate and Diisononyl hexahydrophthalate. Its molecular formula is C26H46O4-2, with a molecular weight of 422.64104. This substance typically presents as a colorless transparent liquid with an impressive assay of 99.5% minimum. Key technical specifications underscore its high quality and performance: a low color value of ≤15 APHA, an acid value of ≤0.1 mg KOH/g, and an ester content of ≥99.5% by weight. Its specific gravity at 20℃ ranges from 0.950-0.965 g/cm3, with a water content of ≤0.1% by weight. A high flash point of ≥190℃ ensures safety in handling, while its rotational viscosity at 25℃ is between 30-50 mPa.s, and its refractive index *n20D is 1.460-1.466. Crucially, its phthalate content is extremely low, at ≤0.01%, signifying its non-phthalate status. Furthermore, tests confirm extremely low levels of heavy metals such as Sb, As, Ba, Sn, Cr, Pb, Hg, Se, and Cd, far below regulatory limits, making it a preferred choice for sensitive applications.

Plasticizers function by embedding themselves between polymer chains, effectively reducing the intermolecular forces that hold these chains together. This process increases the free volume within the polymer matrix, allowing molecular segments to move more freely. The result is a material that is softer, more flexible, and easier to shape and mold, dramatically expanding its range of practical uses. Without plasticizers, many polymers, especially polyvinyl chloride (PVC), would be rigid and brittle, severely limiting their applicability.

DINCH's versatility makes it suitable for all kinds of high-class PVC products, including those produced through calendering, extrusion, and in both rigid and semi-rigid forms. Its exceptional profile makes it highly recommended for sensitive consumer and medical applications, such as children's toys, food packaging film, plastic wrap, medical tubes, food-contacted gloves, wall paper, decorative sheets, and medical blood bags. It demonstrates excellent compatibility with PVC and other polar polymers, and it can be used effectively with all commonly used monomeric plasticizers in PVC. Compared to older generation plasticizers like DOP (Dioctyl Phthalate) and DINP (Diisononyl Phthalate), DINCH offers significant performance advantages, including improved low-temperature flexibility and superior viscosity stability, alongside a lower initial viscosity. These properties contribute to longer-lasting products that maintain their integrity and performance under various environmental conditions.

The chemical industry is continually evolving towards safer and more sustainable solutions. Concerns regarding the environmental persistence and potential health effects of certain traditional plasticizers have driven a global shift towards alternatives like DINCH. Regulatory bodies worldwide have increasingly imposed restrictions on specific compounds, highlighting the importance of choosing well-researched and approved plasticizers. DINCH aligns perfectly with this trend, providing a robust and responsible solution without compromising performance.

For optimal product integrity, DINCH is typically available in 200kg drums or IBC drums, and should be stored in a cool, ventilated indoor area, ensuring a storage period of two years. This meticulous approach to packaging and storage safeguards its quality until ready for use. For those looking to source this high-quality Di-Isononyl-cyclohexane-1,2-dicarboxylate, it is essential to partner with a reliable DINCH manufacturer and supplier that can ensure consistent product quality and timely delivery. Inquiries about DINCH price and specifications, or to discuss purchase options, can lead to a long-term, mutually beneficial relationship in the chemical supply chain.
