Jinzhou Runda Chemical Co., Ltd.

Based in China, Jinzhou Runda Chemical Co., Ltd. lists 26 active products across Chemicals & Allied Products, Petroleum By‑Products, Lubricants and Adhesive, Sealants & Lubricants categories. The catalogue includes generic lubricant additives, specialized anti‑wear hydraulic fluid packages, and a 4‑Stroke Motor Engine Oil Additive recorded under HS code 3403.19 as a multi‑component detergent‑dispersant concentrate with a petroleum oil carrier. Other entries feature a 2‑Stroke Gasoline Engine Oil Additive Package (HS 3403.19, mineral‑based detergent‑dispersant), a phenolic antioxidant (RD501, HS 2907.19), zinc dioctyl dithiophosphate (ZDDP, HS 3811.21) and several calcium‑based sulfonate detergents (HS 3811.29 and HS 3403.19). Additional products cover silicone‑based antifoam agents (HS 3824.99 and HS 3402.13), pour‑point depressants, and an ethylene‑propylene rubber (EPM, HS 3901.30).

The supplier’s catalogue concentrates on additive chemistry for engine, gear and hydraulic oils. Products such as zinc‑butyl octyl primary alkyl dithiophosphate and ZDDP are typical anti‑wear agents supplied at 5‑12 % phosphorus‑based concentration and are evaluated against ASTM D4740. Calcium sulfonate detergents are offered in high‑base (120‑150 mg KOH g⁻¹) and middle‑base (80‑100 mg KOH g⁻¹) grades, matching common ACEA C3 specifications. Antifoam agents are silicone‑based formulations with cloud points below - 20 °C, while polymeric pour‑point depressants are designed to lower the pour point by 10‑20 °C in mineral‑based oils. The EPM polymer is supplied as a raw copolymer used for EPDM‑type elastomers, typically characterized by Mooney viscosity 40 - 70.
