310S Direct Roving is produced by using E6 glass formulation and coated with a silane-based sizing. It is specially designed for the reinforcement of epoxy resins and suitable for internal or
external unwinding in filament winding processes.
The articles of epoxy resin reinforced with 310S possess excellent mechanical and electrical properties, and can be used to produce hollow insulation bushings, insulation rods and ultrahigh voltage composite insulators for power generation, transmission and distribution applications.
Product Features
- Suitable for high-speed and high-tension winding
- Suitable for external unwinding
- Excellent electrical properties and mechanical properties
- Excellent chemical corrosion resistance
