There are significant differences in fiber length, strength, and application scenarios between ground fiberglass powder and fiberglass chopped strands.
Fiber length and strength
Fiber length: Grated glass fiber powder is used to crush glass fiber waste wire (scraps) into powders and staple fibers of different lengths through a crushing process. Therefore, the fiber lengths are different and may contain powder. The fiberglass chopped strands is manufactured by cutting process, with high fiber length accuracy, consistent monofilament diameter, and the fiber remains segmented before dispersing, which has good fluidity.
Strength: Due to the different fiber lengths of the ground fiberglass powder, the strength is difficult to guarantee. The strength values of all corners may be inconsistent, and it is easy to stagger and clump. The tensile strength of the fiberglass chopped strands in the product is consistent, it can form a three-dimensional mesh structure, and it has high elasticity, tensile strength and impact strength.
Application scenario
Ground fiberglass powder: Due to its unstable strength, it is usually not used alone, but is added to other materials as a filler to enhance the overall performance of the material.
Fiberglass chopped strands: Due to its high strength, good fluidity, no static electricity and other characteristics, it is widely used in composite materials, electrical insulation materials, thermal insulation materials and other fields. The high-grade supply of fiberglass wire is also used in the manufacture of electrical equipment parts with high strength and good dielectric properties.
Production process and characteristics
Production process: Ground fiberglass powder is made by crushing process, while short shredded fiberglass is made by cutting process.
Characteristics: Because the ground fiberglass powder is made from waste materials, there are many impurities and the diameter of the monofilament varies. The short shredded glass fiber has a high fiber content and consistent fiber length, no static electricity, high temperature resistance, and is suitable for use in application scenarios that require high strength.
