Import Epoxidized Soybean Oil — Buy in Bulk from Supplier in China

Longkou Longda Chemicals Co., Ltd., based in Longkou, Yantai, China, supplies epoxidized soybean oil (ESO) as a renewable plasticiser and stabiliser. The supplier specifies a maximum epoxy value of 180 Pt‑Co and a minimum epoxy content of 6.2 % (equivalent to 6.8 % under ASTM D1652). Purity is reported to meet stringent industry standards, and the product is derived from soybean oil, supporting sustainable formulations. This ESO complies with ISO and SGS certification programmes offered by the supplier.

In the broader market ESO typically exhibits a density around 0.92 g/mL and a flash point above 150 °C, characteristics that aid processing safety. Standard industrial grades maintain a viscosity of 30‑50 cSt at 40 °C and an acid value below 0.5 mg KOH/g, parameters that align with the specifications listed by Longda. The high epoxy value enables strong compatibility with polyvinyl chloride and other polymers, while the renewable origin reduces the carbon footprint of end‑products. Such typical properties are recognised across plastics, coatings and adhesive sectors.

The material is widely used in PVC formulations, coating resins and adhesive systems where flexibility and durability are required. Buyers such as polymer manufacturers, coating producers and adhesive formulators typically request flexible minimum order quantities and may select FOB or CIF shipping terms. The supplier indicates that packaging can be customised to buyer needs, and ISO/SGS certifications are available on request, providing a clear quality assurance pathway for importers.

Longkou Longda Chemicals Co., Ltd. is listed with an address in Zhangzheng Village, Xinjia Town, Longkou, Yantai, China. The company is classified as an imported‑tier supplier and carries a harbor trust tier; however, the platform records a 0 % response rate and no average response time, indicating that direct communication has not been documented on the marketplace.

The firm markets epoxidized soybean oil among its chemical offerings, highlighting its renewable origin and performance benefits.
