Dipentaerythritol

Dipentaerythritol from Jiangsu Ruiyang Chemical Plant is a multi-functional polyol with the molecular formula C15H30O5, designed for use in high-durability coatings and crosslinked polymer systems. The supplier references export-grade purity and compatibility with solvents and resins, but provides no numerical data for melting point, density, or moisture content. It is described as a white crystalline powder suitable for industrial-scale formulation.

This material is typically produced through esterification of pentaerythritol and formaldehyde, resulting in a structure with five hydroxyl groups that enable dense crosslinking. In paint systems, it improves hardness, chemical resistance, and gloss retention. The absence of specified impurity limits suggests the product meets general industrial standards, but buyers should request chromatographic analysis for unreacted intermediates.

Primary buyers include manufacturers of powder coatings, wood varnishes, and high-temperature adhesives in Asia, Europe, and North America. Packaging is in 25 kg bags, with bulk container options available. Trade terms are typically FOB or CIF from Chinese ports. MOQ and lead time are not stated; buyers must confirm these directly with the supplier.

Jiangsu Ruiyang Chemical Plant is listed as a supplier based in Liyang, Jiangsu Province, China. The supplier is classified as harbor-tier, indicating basic export verification, but no company history, certifications, production volume, or facility details are disclosed. There is no mention of whether the plant manufactures the material or sources it from third parties.
