Polyester Fibreglass Dogbone Pultrusions
Superior Physical and Electrical Properties
Glastic® dogbone pultrusions are made from fibreglass-reinforced thermoset polyester. The continuous-filament fibreglass roving of each solid dogbone provides excellent strength. All dogbone pultrusions feature:
 | High physical strength |
| Excellent dielectric properties |
| Dimensional stability |
| Resistance to common solvents |
| Heat resistance |
| High strength to weight ratio |
| Low water absorption |
Grade MTS
Most economical system for electrical use; designed for 155°C service, 50
000 psi tensile and 80 000 psi flexural strength.
Grade SG-200
Highest temperature - rated for 210°C service. Excellent thermal
endurance. Ideal replacement for silicone rod.
