Fiberglass chopped strand mat and seam mat are both fiberglass products, and both are glass fiber mats.Production ProcessFiberglass chopped strand mat : It is a non-woven reinforcing material made by cutting continuous glass fibers, uniformly distributing them without orientation, and applying powder or emulsion binder.Fiberglass stitched felt: It is a non-woven reinforcing material made of glass fiber rovings chopped to a certain length, laid evenly without orientation, and then sewn with threads.

Fiberglass is a composite raw material. It has strong corrosion resistance, insulation and other advantages and is used in various fields. Generally, there are three main reasons that affect the strength of  fiberglass chopped strand mat:First, the strength of  fiberglass, the strength and stiffness of  fiberglass directly affect the strength of chopped strand mat. The higher the tensile strength of the glass fiber, the greater the toughness, and the higher the tensile strength of the chopped strand mat produced.Second, the binder content. The production of Nanjing EFG fiberglass chopped strand mat needs to be produced strictly according to customer needs. When the fiber strength is determined, the strength of the chopped strand mat needs to be improved by the binder content. Generally speaking, the higher the binder content, the higher the tensile strength of the chopped strand mat.Third, the storage time. The storage time of fiberglass chopped strand mat still has some influence on its strength. After a long period of storage, the strength will decrease. This phenomenon is due to the aging of glass fiber and the chemicalization of adhesives. It is mainly caused by the erosion effect of moisture in the air on the fiberglass.

1. Fiberglass materials are used in 3D printing technology and the production of electrical insulation, and are also widely used in the production of FRP.2. Fiberglass materials are used to produce fiberglass surface mats, etc., and are also used to reinforce asphalt roofing materials.3. Fiberglass materials are used in military industry, space, bulletproof armor and sports equipment.4. Fiberglass material is a new type of green and environment-friendly reinforcing material used in high-performance reinforced (cement) concrete.

Fiberglass chopped strand mat is suitable for the production of hand lay-up or molded FRP products. Generally, 600 grams of chopped strand mat is widely used in various products such as automobiles, ship hulls, sanitary ware, electrical insulators, anti-corrosion, and pipelines.Fiberglass chopped strand mat (referred to as chopped strand mat) is a non-alkali or non-alkali or non-alkali fiber made of glass fibers chopped into 50 mm length, uniformly distributed without orientation, and bonded with polyester powder and polyester emulsion binder. Medium-alkali glass fiber non-woven felt products.
