Item # 1494, Grade 1494 Arc/Track & Flame Resistant Laminate



  • 1,000 Minutes Track Resistance
  • Electrically Insulating
  • Highly Flame Resistant
  • Low Smoke & Smoke Toxicity
  • UL® Recognized
  • NEMA Grade GPO-3
Glastic® Grade 1494 is a fiberglass reinforced thermoset polyester material. It is available in sheet form as well as a wide selection of channel, angle, and tube sizes. These materials are the industry standard for flame and arc/track resistant electrical insulation. In addition, the excellent combination of high strength, flame resistance, and low smoke generation has given it application in many other areas such as transit and marine where safe, yet economical materials are required. Additional information and samples can be obtained through Glastic Customer Service or your local Glastic authorized distributor.
