Fiberglass chopped strands are short lengths of fiberglass fibers, typically around 1 to 3 inches in length, that are used as a reinforcing material in various composite applications.

Some common applications of fiberglass chopped strands include:

Reinforcing thermoplastics: Fiberglass chopped strands are often added to thermoplastic materials such as polypropylene, nylon, and polycarbonate to improve their strength and stiffness.

Reinforcing thermosetting plastics: Fiberglass chopped strands can also be used to reinforce thermosetting plastics such as polyester and epoxy resins, which are commonly used in the manufacture of boats, automobile parts, and other products.

Construction materials: Fiberglass chopped strands can be used as a reinforcement in various construction materials such as concrete, mortar, and plaster to improve their durability and strength.

Filtration media: Fiberglass chopped strands can be used in the manufacture of filter media for air and liquid filtration applications.

Insulation materials: Fiberglass chopped strands can be used in the manufacture of insulation materials such as fiberglass batts and blown-in insulation.

Overall, fiberglass chopped strands are a versatile and widely used material for reinforcing and improving the properties of various composite materials.
