1800 Glastic Grade FHT

Note: This is a variation of Glastic SG-200 & FHT Sheet (SG-200 is a 410ºF Fiberglass Reinforced Polyester Sheet / FHT is a 392ºF Flexible High Temp. Laminate).

SG-200 and FHT are the highest temperature FRP composite materials. They offer similar properties as the lower temperature materials, and SG-200 has excellent machinability. SG-200 is the rigid version, and FHT is the flexible version.

Additional Information

  • Highly Flexible
  • Excellent Dielectric Strength
  • High Heat Resistance
  • Ideal For Dry-Type Transformers
  • Easily Fabricated
  • Asbestos-Free
Glastic® Grade FHT (Flexible High Temperature) Laminate provides numerous high-performance features and benefits, such as high flexibility and excellent dielectric strength at elevated temperatures. It also exhibits the highest UL temperature index in the industry for a flexible glass-reinforced polyester in 1/32 inch and 1/16 inch thicknesses:
  • 1/32 inch – 190ºC Electrical
  • 1/16 inch – 200ºC Electrical
  • 1/32 inch – 190ºC Mechanical
  • 1/16 inch – 200ºC Mechanical
With its high resistance to heat, Glastic’s FHT Laminate offers a cost-effective alternative to aramid paper in 220ºC insulation systems. Typical applications include layer and core insulation for dry-type transformers. Glastic Grade FHT Laminate standard color is tan.
