To protect sensitive PCB electronics in battery management systems (BMS).

POLYURETHANE POTTING COMPOUNDS FOR BATTERY MANAGEMENT SYSTEMS

We supply polyurethane electronic potting compounds to protect sensitive PCB electronics in battery management systems (BMS).Our custom potting compounds meet standards for performance, reliability, and safety. Protective resins engineered to function under extreme parameters ensure your battery management system keeps batteries working within safe and efficient operating ranges. Typical problems managed in choosing or formulating your best encapsulant/potting compound:

Avoiding/overcoming thermal runaway propagation
Mitigating thermal conductivity
Thermal shock chambers
Thermal cycling chambers
Performance in extreme temperatures (high and low)

BMS Potting Compound Advantages

Polyurethane is preferred for use with electronics because of its electrical insulation, thermal shock resistance and thermal conductivity. Our BMS potting compounds such as EPIC RM2018, S7527 and S7475 offer:

Excellent flexibility
Thermal shock and cycling protection
Low weight loss at elevated temperatures
Convenient mix ratios for meter mix and dispense applications
UL94 V-0 flammability rating
Low Tg and component stress
