What is the difference between ground fiberglass powder and chopped fiberglass?

2023-02-17

In the market, many people don't know much about ground fiberglass powder and fiberglass chopped shreds, and they are often confused. Today we will introduce the difference between them:

Grinding  fiberglass powder is to crush fiberglass waste (scrap) into different lengths (mesh numbers) by crushing process, and fiberglass chopped strands are produced by cutting process to produce different lengths

Advantages of fiberglass chopped strands: high fiber length accuracy, high fiber content, consistent single filament diameter, good fluidity in segmented fiber before dispersion, because it is inorganic, it does not generate static electricity, high temperature resistance, in The tensile force in the product is consistent and can form a three-dimensional network structure, so that the product has good willfulness and tensile strength, high impact strength, and the length of fibers dispersed in each corner of the product is consistent, so the tensile strength of the product is consistent.

Grinding fiberglass powder cannot be done, because it is a crushing process, and the length of the fiber cannot be guaranteed. The diameter is not guaranteed, and the fibers are thick or thin, so after adding it to the product, the strength cannot be guaranteed. The strength values of each corner are different, and it is easy to stagger and form lumps.
