Description

Glass Fibers CAS NO 308066-84-4 are high-performance inorganic materials engineered for reinforcement and composite applications. They are valued for their exceptional tensile strength, dimensional stability, and resistance to heat and chemical corrosion. These fibers are essential for manufacturers in the automotive, aerospace, construction, and electronics industries seeking to enhance the mechanical properties of their products.

Application

• Polymer Composite Reinforcement: Primary reinforcement in thermoset (polyester, epoxy) and thermoplastic composites for automotive parts, wind turbine blades, and sporting goods.
• Construction Materials: Used in fiberglass-reinforced concrete (GRC), gypsum boards, and roofing materials to improve crack resistance and durability.
• Electrical & Thermal Insulation: Manufacture of circuit boards (FR-4), electrical insulation tapes, and high-temperature insulation blankets.
• Filtration Media: Production of high-efficiency air and liquid filter bags and cartridges for industrial applications.
• Aerospace Components: Reinforcement in lightweight structural components for aircraft interiors and secondary structures.
• Marine Applications: Key material in boat hulls and marine structures due to its resistance to water and salt corrosion.

Quality Control

Our Glass Fibers are manufactured under a stringent quality management system. Each batch is tested to ensure consistency in fiber diameter, tensile strength, and chemical composition. We provide comprehensive Certificates of Analysis (COA) detailing key parameters, and our production can adhere to relevant ISO standards. Custom specifications for different glass types (E-glass, S-glass, etc.) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and strong alkalis. The product is hygroscopic (moisture-sensitive); ensure packaging integrity is maintained to prevent moisture absorption which can affect performance.
