Our lithium-ion battery potting materials protect from moisture and chemical exposure while guarding against damage from mechanical and temperature shock. Lightweight lithium batteries are ideal power sources for smaller consumer products exposed to environmental stresses.

We design, formulate, and manufacture polyurethane and epoxy resin potting and encapsulating compounds for lithium-ion (Li-Ion) battery packs. Our products can overcome and work to avoid thermal runaway propagation. Where applicable, we will help you choose the right compound for mitigating thermal runaway in your lithium-ion battery. We partner with our customers, managing issues with thermal conductivity, thermal cycling, thermal shock chambers, and extremely high and low temperatures.

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 S7527 is a two component polyurethane potting compound formulated for applications requiring thermal stability at high temperatures. S7527 carries a UL 94V-0 flame rating and a 150°C RTI rating per UL 746. Epic S7527 is excellent for potting and encapsulating sensitive electronics which will be exposed to harsh environments.

Epic S7571 is a two component urethane potting compound that was developed for the lithium-ion battery market. It features a very low Tg (<-60°C), is flexible (80 shore A), is designed to pass UL 94 V-0 at ¼", and has decent thermal conductivity (0.6-0.7 W/mk) for material that has a lower density than most other UL 94 V-0 systems. The reduced density decreases the weight of the finished product while maintaining the thermal conductivity needed.

Epic S7591 is a two component epoxy that is designed for high temperature applications. S7591 features a low thermal expansion rate coupled with a high glass transition temperature. The S7591 is also designed to provide an extremely high 3W/mK thermal conductivity for rapid removal of heat generated by electrical/electronic components.
