 Direct Roving for Filament Winding

 

308 Direct Roving For Filament Winding

308 Direct Roving is produced using E6 glass formulation and coated with a silane-based sizing. It is specifically designed to reinforce epoxy resins and is suitable for amine or anhydride curing systems.

The combination of 308 and epoxy resin delivers excellent mechanical properties and fatigue resistance. 908 is suitable for high tension filament winding process to manufacture small-diameter sucker sods. High pressure pipes, storage tanks, and pressure vessels.

Product Feature

l         Complete and fast west-out

l         Good abrasion resistance and smooth transfer between packages under high tension

l         High mechanical strength and good fatigue resistance

l         Superior chemical corrosion resistance

Storage

Unless otherwise specified, the fiberglass products should be stored in a dry ,cool and moisture-proof area. The room temperature and humidity should be always maintained at 15C~35C and 35%~65%.It is best if the product is used within 12months after production date .The fiberglass products should remain in their original packaging until just prior to user.

To ensure safety and avoid damage to the product, the pallets should not be stacked more than three layers high. When the pallets are stacked in 2 or 3 layers, special care should be taken to correctly and smoothly move the top pallet
