从China供应商批发进口Adipic Acid — FOB条款

Petrochina supplies adipic acid (hexanedioic acid, C6H10O4) as a white crystalline industrial chemical with stated minimum purity of 99.5%. This dicarboxylic acid serves as the primary monomer for nylon 6,6 polyamide production, with additional uses in polyurethane synthesis, synthetic lubricants, and plasticiser formulations. The supplier packages material in 25 kg bags or 500 kg FIBC bulk bags, configurations suited to both small-batch processors and large-scale polymer plants. Petrochina operates from Karamay in Xinjiang Uygur Autonomous Region, a location tied to China's petrochemical corridor with access to feedstock from regional refining operations.

The 99.5% purity grade represents standard technical material, slightly below the 99.7% threshold of premium polymer grades, though still suitable for many industrial applications depending on end-use sensitivity to impurities. Industrial adipic acid production typically proceeds via cyclohexane oxidation to cyclohexanone and cyclohexanol (KA oil), followed by nitric acid oxidation to the dicarboxylic acid. Residual nitrate and nitrite from this route can catalyse degradation in sensitive polyurethane systems. The 25 kg and 500 kg packaging options correspond to standard export configurations, with the FIBC format reducing handling costs for volume buyers while the smaller bags suit distributors and specialty chemical blenders.

Key buyer segments encompass synthetic fibre producers spinning nylon 6,6 for tyre cord, airbag fabric, and industrial belting; polyurethane manufacturers formulating rigid and flexible foams for construction and automotive seating; and compounders creating adipate ester plasticisers for PVC modification. The food acidulant market (E355) represents a smaller but regulated niche requiring additional purity certifications. With Petrochina's state-owned enterprise status, buyers may access consolidated logistics and credit terms, though direct negotiation remains essential. The listing does not specify MOQ, pricing, or lead time, so buyers must confirm these parameters through direct inquiry.

Petrochina, headquartered in Karamay, Xinjiang Uygur Autonomous Region (postal code 833600), operates as a major state-owned petroleum and petrochemical enterprise in China. The Karamay location reflects proximity to significant oilfield operations and downstream refining capacity, providing integrated feedstock access for chemical production. The supplier carries a harbor trust tier designation on this platform, with a recorded response rate of 0.00% and zero average response hours, indicating no tracked inquiry activity or non-functional response measurement. The profile contains no stated production capacity, employee count, establishment date, or export volume data.

The listing presents Petrochina as a producer of adipic acid with specified material composition and packaging, though it does not clarify whether this represents direct manufacturing or trading division activity. No factory audit information, environmental compliance statements, or specific quality management system certifications are detailed in the available profile. Buyers should independently verify whether the Karamay facility produces adipic acid through integrated cyclohexane oxidation or sources material from other Petrochina group affiliates. The absence of response statistics suggests either a newly listed profile, inactive account, or platform data collection gap, necessitating direct outreach through official Petrochina channels to establish commercial contact.
