Polyester Fibreglass Round Pultrusions
Superior Physical and Electrical Properties
Glastic® round pultrusions are made from fibreglass-reinforced thermoset polyester. The continuous-filament fibreglass roving of each solid round provides excellent strength. All round 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 HIR
Highest physical properties. Electrical properties and high
temperature capabilities - Class H (200°C). Dimensional stability and
100,000 psi flexural strength. Resistant to fluids commonly used around
electrical equipment. Greater cost efficiency than epoxy, phenolic, nylon,
or brass rod.
