Global Thermal Runaway Insulation Blanket Market Strategic Research Report

Scope of the Report

The global Thermal Runaway Insulation Blanket market size is predicted to grow from US$ 1,457 million in 2025 to US$ 4,138 million in 2032; it is expected to grow at a CAGR of 15.9% from 2026 to 2032.

Thermal runaway insulation blanket is a high-performance thermal barrier material used in lithium-ion battery systems to delay or prevent the propagation of heat during a thermal runaway event. It typically features high temperature resistance, low thermal conductivity, flame retardancy, electrical insulation, and structural stability. It is widely used in EV battery packs, energy storage systems (ESS), and aerospace battery safety protection. In 2025, global Thermal runaway insulation blanket production reached approximately 83.01 Kilotons. The upstream of the thermal runaway insulation blanket industry consists of high-performance raw materials, including ceramic fibers, aerogel precursors, aramid fibers, glass fibers, flame-retardant resins, and inorganic fillers.

Thermal runaway insulation blankets are critical functional safety materials in lithium-ion battery systems, primarily used in EV battery packs and energy storage systems (ESS) to isolate and block heat propagation during thermal runaway events, thereby reducing the risk of cascading failures and improving overall system safety. With the rapid growth of the electric vehicle and energy storage industries, battery energy density continues to increase, leading to higher thermal instability risks. At the same time, increasingly stringent global safety regulations, such as UN38.3, UL9540A, and China’s GB standards, are driving the adoption of advanced thermal propagation protection materials. As a result, thermal runaway insulation blankets have evolved from auxiliary fire-resistant components into standard safety structural elements in battery pack design.
