DOWSIL™ EF-6559 Silicone Foam

What is DOWSIL™ EF-6559 Silicone Foam?

Two-part, room temperature cure silicone foam which is fire resistant, has dielectric properties and is used for battery fire protection. It can be applied by automated dispensing systems.

Uses

1:1 mix ratio
Low viscosity
Medium density foam (~0.45 g/cm³)
Resists thermal propagation, high heat, and fire by forming a protective ceramic layer to help reduce thermal runaway risk
Low thermal conductivity and lightweight, medium-density foam which provides effective insulation without adding significant mass
Designed for production of automated, high-volume series production and compatibility with standard meter mix dispense equipment
Strong electrical insulation with high dielectric strength and CTI 600 which supports safety in high-voltage battery environments
Stable elastomeric foam which offers uniform cell structure, compression resistance, and durability across wide operating temperatures

Benefits

EV Battery fire protection for potting and cavity filling in high-voltage systems, especially for pouch cell designs
EV Battery modules assembly
EV Battery stock potting
