Polyacrylonitrile price

The price of PAN is primarily driven by its molecular weight distribution, purity levels, and physical form (powder, fiber, or solution). For industrial applications, a homopolymer typically costs less than copolymers (such as those containing methyl acrylate or vinyl acetate) which are engineered for specific solubility or carbonization properties. Buyers should verify the intrinsic viscosity and moisture content (<0.5%) as these directly impact processing efficiency and final product quality.

Usage scenarios dictate the grade and cost. Carbon fiber precursor grade PAN requires extreme purity and specific filament counts (e.g., 12K, 24K, or 48K), commanding a premium price. In contrast, textile-grade PAN (acrylic fiber) focuses on dyeability and hand-feel, where cost-efficiency is prioritized. For water treatment membranes, the focus shifts to pore size consistency and chemical resistance, requiring suppliers to provide detailed scanning electron microscopy (SEM) reports.

Suppliers should provide Material Safety Data Sheets (MSDS) and comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for European markets. If the PAN is used in filtration for food or medical contact, FDA compliance or ISO 10993 may be necessary. Ensure the manufacturer holds ISO 9001:2015 for quality management and ISO 14001 for environmental standards, as chemical synthesis is subject to strict environmental audits.

Buyers should analyze the Total Cost of Ownership (TCO) by factoring in the monomer (Acrylonitrile) price index, as PAN prices fluctuate with crude oil and propylene markets. Seek suppliers on Made-in-China.com that offer tiered pricing models based on volume (e.g., 5-ton vs. 20-ton orders). Additionally, evaluate the yield rate; a slightly more expensive high-purity resin may reduce waste and machine downtime, proving more economical in the long run.

The main risks include quality inconsistency between batches and volatility in shipping costs for hazardous or bulky chemical goods. To mitigate these, use Trade Assurance services and mandate third-party inspections (such as SGS or Intertek) before balance payments are made. Ensure the packaging is moisture-proof and UV-resistant (e.g., vacuum-sealed aluminum foil bags) to prevent polymer degradation during long-sea transit.

Focus on long-term contract pricing rather than spot-market buys to hedge against raw material price spikes. Negotiate for customized packaging or labeling at no extra cost for bulk orders. Inquire about technical support availability, such as assistance with solvent selection (DMF, DMSO, or NaSCN) for spinning processes, which adds significant value beyond the base product price.

PAN powder is generally classified as non-hazardous, but it must be accompanied by a Certificate for Safe Transport of Chemical Goods. Ensure the HS Code (typically 3901.40 or 3906.90) is correctly declared to avoid customs delays or incorrect tariff applications. For shipping to the US or EU, verify if any anti-dumping duties apply to specific synthetic fiber categories originating from the supplier's region.

Prioritize Audited Suppliers who have undergone comprehensive on-site verification by independent agencies. Utilize the Secured Payment system to ensure funds are only released upon confirmed receipt of goods. Always conduct video audits of the production line to confirm the supplier's actual manufacturing capacity and storage conditions for chemical resins.
