Fiberglass Chopped Strand is a high-performance reinforcement material widely used in composite manufacturing to enhance the mechanical properties and durability of various products. These strands are short glass fibers cut to specific lengths—typically 3 mm, 6 mm, 12 mm, or 25 mm—and are coated with sizing agents compatible with different resin systems such as polyester, epoxy, vinyl ester, and phenolic resins. With a fiber diameter ranging from 13 to 24 microns and a density of approximately 2.6 g/cm³, these chopped strands offer excellent tensile strength, impact resistance, and thermal stability. The low moisture content (≤ 0.10%) further enhances their performance in various applications.

Fiberglass Chopped Strands are categorized based on their length, fiber diameter, and the type of resin compatibility. They are available in different formulations to meet the specific needs of different industries and processing methods, such as injection molding, compression molding, and extrusion. Key features include their high strength-to-weight ratio, resistance to corrosion and chemicals, and ability to maintain mechanical properties under high temperatures, making them suitable for demanding applications.

These chopped strands are used across multiple industries, including automotive, where they reinforce thermoplastic and thermoset composites for lightweight and high-strength components like bumpers and panels. In the construction sector, they are used to enhance the tensile strength and crack resistance of concrete and other building materials. In electrical and electronic applications, they provide insulation and structural integrity for components exposed to heat and electrical stress. In consumer goods, they improve the durability of products such as sporting goods and appliances. Additionally, in marine and aerospace applications, they are essential for producing lightweight, corrosion-resistant parts that can withstand harsh environmental conditions. Overall, Fiberglass Chopped Strands provide a cost-effective solution for reinforcing composites, delivering superior performance and versatility in a wide range of applications.
