1906 Glastic Grade SG-200

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

  • Extremely Strong
  • Excellent Retention Of Properties At Elevated Temperatures
  • Ideal For High Temperature Applications
  • Easily Fabricated
  • Asbestos-Free
Glastic Grade SG-200 High-Strength & High-Temperature Laminate offers the same high-performance features and benefits as Glastic’s FHT Laminate. In addition, SG-200 offers much higher mechanical strengths than FHT with temperature ratings of up to 210ºC.

Because of its capabilities, Glastic SG-200 is ideal for a wide variety of product applications requiring high temperature NEMA GPO-1 products. Grade SG-200 is also a superior replacement material for epoxy-bonded mica in layer insulation applications. SG-200 has a UL Temperature Index of 210ºC Electrical and 210ºC Mechanical. Glastic Grade SG-200 is available in thicknesses of 1/32″ to 1-1/4″ and in a natural tan color. Special sheet sizes of 64″ x 64″ are available for large lifting magnets.
