March 17, 2026 — Driven by rising upstream crude oil prices and cost pass-through along the benzene-adjipic acid chain, the engineering plastics market is experiencing a new wave of price adjustments. Among these, products like PA12, high-temperature nylons (PA12T/PA10T, etc.), PA66, and long-carbon-chain nylons (PA12 elastomers) continue to see price strength. The 5%-10% price increase across the entire PA12 series announced by Wanhua Chemical earlier this month has now been fully implemented.

Clear Industrial Chain Transmission Path

The transmission path for this round of price increases is exceptionally clear: rising crude oil prices → benzene → adipic acid → polyamide (nylon). Data from ICIS shows that while the recent escalation of the Middle East conflict has no direct substantive impact on domestic PA66 import and export trade, it drives up bulk commodity prices through the top-down transmission along the crude oil industry chain. The cost-side support for the domestic PA66 industry chain is strong, and product prices are actively rising in line with high raw material costs.

As one of the few companies globally mastering the entire PA12 industry chain, Wanhua Chemical has previously completed multiple rounds of price increases for core products such as MDI, TDI, and TPU, giving it strong pricing power. This latest adjustment for the PA12 series further consolidates its leading position in the high-end nylon market.

High-Temperature Nylons Like LCP/PPA Attract Attention

Meanwhile, specialty engineering plastics such as Liquid Crystal Polymer (LCP) and high-temperature nylons (PPA) are also receiving significant market attention. These materials, with their excellent high-temperature resistance and dimensional stability, are irreplaceable in fields like consumer electronics and automotive connectors. Despite increased cost pressures, downstream customers, to ensure supply chain stability, maintain a strong willingness to purchase high-end materials with core technologies.
