Glastic® FHT
Glastic® FHT - Flexible High-Temperature Laminate
Grade Glastic® FHT (Flexible High Temperature) Laminate provides numerous high-performance features and benefits, such as high flexibility and excellent dielectric strength at elevated temperatures.
Some attributes:
- Highly flexible
- Excellent dielectric strength
- High heat resistance
- Ideal for dry-type transformers
- Easily fabricated
- Asbestos-free
It also exhibits one of the highest UL® temperature indices in the industry for a flexible glass-reinforced polyester in 0.8 mm and 1.6 mm thicknesses:
- 0.8 mm – 190° C Electrical
- 1.6 mm – 200° C Electrical
- 0.8 mm – 190° C Mechanical
- 1.6 mm – 200° C Mechanical
With its high resistance to heat, Glastic® FHT Laminate offers a cost-effective alternative to aramid paper in 220°C insulation systems. Typical applications include layer and core insulationfor dry-type transformers.
