Description

Fibrous Glass is a high-performance, inorganic synthetic material composed of fine, flexible fibers of glass. This versatile material is engineered for exceptional thermal insulation, acoustic dampening, and reinforcement properties, making it a critical component in demanding industrial and construction applications. Key industries that rely on its unique characteristics include building and construction, automotive manufacturing, aerospace, and industrial filtration.

Application

• Thermal and Acoustic Insulation: Primary material for insulating batts, rolls, and boards in residential, commercial, and industrial buildings.
• Composite Reinforcement: Used as glass fiber reinforcement (GFRP) in plastics, resins, and concrete to enhance structural strength and durability.
• Filtration Media: Manufactured into high-efficiency filter papers, bags, and cartridges for air and liquid filtration systems.
• Automotive Components: Found in molded parts for lightweight body panels, under-hood insulation, and interior acoustic management.
• Aerospace and Marine: Utilized in lightweight composite structures for aircraft, boats, and wind turbine blades.
• Technical Textiles: Basis for fire-resistant fabrics, electrical insulation tapes, and reinforcing scrims.

Quality Control

Our Fibrous Glass is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as fiber diameter, length distribution, chemical composition, and tensile strength are rigorously tested. Certificates of Analysis (COA) detailing specific lot characteristics are available upon request, and our quality systems support compliance with relevant industry and safety standards.

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 sources of moisture and incompatible materials. Handle with appropriate personal protective equipment to avoid irritation from loose fibers.
