Thermally Conductive UL 94 VO Potting Compound


UL 94 V-O listed 50-2369 FR is the fastest self extinguishing Thermally Conductive Polyurethane Potting Compound available on the market today. It offers a unique combination of properties seldom seen in a Thermally Conductive Potting Compound. 50-2369 FR provides a quick heat dissipating system in a polyurethane chemistry, while also passing UL's 94 V-O self extinguishing test. There is no other Potting Compound that is UL 94 V-O Listed with this unique combination of properties: • Thermally Conductive- 50-2369 FR is the perfect solution for today's electronics, which are getting smaller and are generating more heat, since this two component polyurethane compound helps to cool down electronic assemblies and provides quick heat dissipation away from hot components. • Polyurethane Potting Compound- Many UL 94 V-O listed products are rigid epoxies that stress sensitive components during or after cure. The 50-2369 FR is a tough urethane that cushions and protects electronic components. Also, polyurethanes are often the best choice for outdoor applications due to their moisture and overall weather resistance. • Self Extinguishing- This is the fastest self extinguishing Thermally Conductive Polyurethane Potting Compound. 50-2369 FR has been tested to Underwriter Laboratories (UL) stringent flame retardant UL 94 V-O test. The listing of this product is under UL File Number E235584. • Electrically Insulating- 50-2369 FR provides excellent electrical insulation properties. It therefore protects assemblies and components while helping to maintain the assemblies’ electrical integrity.
