Global PIB and butyl rubber market shows steady demand growth as of late August 2026. The photovoltaic glass and new energy battery sealing sectors become major consumption drivers. Medium & high viscosity PIB for insulating glass hot melt sealants keeps tight spot supply, overseas buyers from Southeast Asia, Middle East and Europe place frequent small batch orders.
Butyl rubber (IIR) domestic quotations stay firm. New production lines are still in capacity ramp-up phase, unable to fully release supply to ease market tension. Downstream manufacturers of waterproof tapes, tire inner tubes and anticorrosion pipelines maintain rigid purchasing needs.
Upstream ethylene and C5 petroleum resin prices stay high, continuously squeezing profit margins of PIB and butyl compound factories. Many manufacturers hold limited inventory and resist low-price shipments.
Export side, RCEP tariff preferences boost cross-border shipments of rubber sealing raw materials. Traders expect obvious demand surge in September with the arrival of overseas construction peak season.
Market participants suggest tracking crude oil trend, domestic petrochemical plant maintenance schedules and overseas infrastructure order volume to judge future price movement of PIB and butyl rubber.
