# S-Glass Fiber Cloth
Compared with conventional alkali-free (E) glass fiber, high-strength S-glass offers higher tensile strength, higher elastic modulus, better impact resistance, superior chemical stability, higher heat tolerance and better fatigue performance.
Key Advantages
- Strong mechanical performance: tensile and flexural strength markedly above E-glass
- Heat tolerance: higher sustained service temperature than ordinary glass fiber
- Chemical stability: resists acids, alkalis and aggressive media
- Fatigue resistance: suitable for cyclic-load duty
- Cost effective: more economical than carbon fiber for large-area reinforcement
Applications
External reinforcement of pressure pipes and pressure vessels — particularly where high temperature, corrosive media, large coverage area or electrical insulation are required.
