Epoxies, Etc 50-3253FR Flame Retardant Thermally Conductive Epoxy Resin
Categories: Polymer; Thermoset; Epoxy; Epoxy, Electrically Conductive

Material Notes: Description: 50-3253FR Potting and Encapsulating Compound has been formulated to meet the stringent non-burning requirements of UL 94 V-0. This medium viscosity system offers high thermal conductivity, low shrinkage, low exotherm, and outstanding electrical insulation properties. The high thermal conductivity helps extend the life of assemblies by quickly dissipating heat away from critical components. 50-3253FR is designed for ease of use. It has a convenient 1:1 mix ratio. Typical applications for the 50-3253FR include potting and encapsulating power supplies, transformers, batteries, coils, insulators, sensors, etc. The 50-3253FR is an excellent choice for applications that require a flame retardant compound with high thermal conductivity.

Features:

  • Thermally conductive
  • Easy 1:1 ratio
  • Shock and vibration resistant
  • Flame Retardant cuitry
Benefits:
  • Protects electronics by quickly transferring heat
  • Ideal for use with meter mix dispense equipment
  • Will not damage electronic components
  • Meets UL94V-0 non-burning requirements
