Haysite Ultratrac® H950 Glass Reinforced Polyester Sheet, Electrical Grade (GPO3)
Categories: Polymer; Thermoset; Composite SMC; Filled/Reinforced Thermoset; Polyester, TS; Thermoset Polyester Glass SMC

Material Notes: This new generation of high performance material meets or exceeds all requirements for NEMA GPO-2 or GPO-3. ULTRATRAC ® H950 is recognized by U.L. as a 94V-0 material and offers greater arc and track protection with no increase in cost. Testing at an independent laboratory shows H950 to be non- toxic as defined by MIL M-14H. Excellent flame resistance and low smoke generation is also characteristic of this material. ULTRATRAC® H950 carries a U.L. thermal recognition of 160ºC electrical/150ºC mechanical. This is the highest rating ever assigned to a flame retardant glass polyester laminate. Applications are typical for GPO-3 materials, but also include components for transportation applications where flame, smoke, and toxicity is of great concern.
