Polyurethane Foam
PORON® EVExtend® Battery Pad Material
Polyurethane battery pad material for EV pressure management, cushioning, and long-term durability
PORON EVExtend® is a family of polyurethane battery pad materials engineered to address the pressure-management challenges of EV and HEV battery designs. It is designed for modern pouch, prismatic, and solid-state battery applications where long-term support and consistent pushback force are critical.
For battery pack designs that need dependable compression performance as cells expand and contract over time, PORON EVExtend® is a strong option. These materials are engineered to help maintain pressure, support battery life, and deliver durable performance throughout the life of the battery.
