308 single-end roving is produced with E6 glass formulation,and coated with a silane-based sizing composition.It is specifically designed for epoxy resin system and suitable for both amine and anhydride curing systems.
308 gives strong resin-to-glass bonding,which results in excellent mechanical and anti-fatigue properties of the end composites. The product is designed for high pressure applications.Typical applications include high pressure pipes,storage tanks,and pressure vessels.
Product Features
- Good bonding with epoxy resin
- Low fuzz and good choppability and dispersion
- Excellent acid corrosion resistance
- Excellent mechanical properties
- Good anti-static property
