Regional Insights
In Southeast Asia countries like Thailand, Indonesia, Malaysia, Vietnam, and the Philippines PI binder usage is emerging alongside nascent battery assembly and EV plans. While currently small in absolute value share, the region benefits from lower-volume cell producers and growing interest in advanced binders for higher safety and irreversibility. Short term growth is moderate, but expansion is anticipated as local EV and battery manufacturing matures.

PI binders remain more expensive than legacy options like PVDF. Adoption is constrained by the need to validate performance gains against added cost and integration complexity. Water-based PI formulations require battery manufacturing line adaptations. Furthermore, material supply chains are still concentrated in Japan and China, potentially exposing Southeast Asian buyers to dependency risks and pricing volatility.

To drive market penetration, binder producers should invest in regional pilot partnerships with Asian battery cell manufacturers to validate lifecycle gains in real-world EV packs. Co-development with Si-anode or high-Ni cathode OEMs can anchor demand. Incentivizing local Southeast Asian battery cell lines through trials and subsidies may accelerate usage. Technology education and manufacturing process support will help bridge integration gaps for water-based binders
