Potting Compounds for Battery Management Systems Include:

Epic RM2018 - Polyurethane Potting Compound for Battery Management Systems

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 S7527 - Potting Material with Long Gel Time

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 S7475 - Battery Management System Applications

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.

Benefits of polyurethanes over silicone potting

  • Lower cost of materials results in a more economical polymer
  • Better bond strength to substrates and cases
  • Durable and efficient in optimal operating temperatures range
    • Low temperature: -60°
    • High temperature: 150°C
  • Higher chemical resistance to more chemical compounds
  • Reduced water vapor permeability increases water-resistance of sensitive components
  • More flexible formulation allows polyurethanes to be formulated soft or rigid
  • More strength, elongation, and abrasion resistance
  • Reduced outgassing from material
