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:
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:
Epic RM2018 is a two-component polyurethane potting and encapsulating compound that carries a UL94 V-0 flammability rating. RM2018 is designed for potting DC/DC converters, GPS sensors, and other electronic devices that require flexibility over a wide temperature range. RM2018 also features a convenient 4:1 volumetric mix ratio, low Tg, and excellent electrical stability over various frequencies.
Epic S7475 is a two-component polyurethane compound for potting electronic control modules and a wide variety of electronic devices. Low mixed viscosity allows the material to flow into intricate areas under printed circuit boards and other tight tolerance areas. A 4:1 mix ratio allows the system to be very adaptable for meter mix and dispense processing. The very low hardness of S7475 in combination with the low Tg provides excellent flexibility, allowing delicate surface-mounted devices to expand and contract during thermal cycling and thermal shock. For applications that generate high heat, S7475 has shown extremely low weight loss at 130°C. It is UL 94 V-0 recognized at 4.8 mm and is RoHS compliant.
Epic S7553 is a two component polyurethane material designed for electronic potting applications. S7553 is a recognized UL 94V0 flame retardant system.
