積水フーラー Company Overview

Total support for battery packs, from thermal runaway measures to structural bonding. Flame-retardant foam solutions that enhance safety, durability, and productivity.

With the expansion of renewable energy and energy storage systems for data centers, advanced safety measures are required for ESS. Our flame-retardant two-component reaction polyurethane foam utilizes technology from the EV battery sector to suppress thermal propagation between cells. This contributes to reducing the risk of thermal runaway and improving the overall safety of battery packs. Additionally, it combines waterproof and moisture-proof properties, lightweight design, and shock absorption, supporting the longevity and manufacturing efficiency of ESS. ■ We want to strengthen thermal runaway measures with the adoption of high-capacity cells. ■ We aim to promote automation and labor-saving while accommodating complex cell shapes. ■ We want to achieve both safety and lightweight durability. ■ We want to realize the longevity of energy storage systems. ▼ Features ■ Suppression of thermal runaway chain reactions Contributes to improving the overall safety of the system by suppressing thermal propagation between cells. ■ Compatibility with all cell types Applicable to a wide range of designs, including cylindrical, prismatic, and pouch cells. ■ Increased productivity Compatible with automated coating processes due to low viscosity and fast curing. ■ Lightweight and highly durable Achieves waterproof and moisture-proof properties in addition to shock absorption and NVH performance. ■ Flame retardant Complies with UL94 V-0.
