Introduction and application of fiberglass chopped strands

Chopped glass fiber is also called glass fiber chopped strand. Quartz sand is melted at high temperature, and the fiberglass raw filaments drawn with special sizing agent (softening agent) are chopped online by wet method, or the product glass fiber is chopped.

It has functions that other glass fibers are difficult to fight, and has an extremely wide range of applications.

Properties of fiberglass chopped strand

1) The strands have good bundling and low dander content.

2) Excellent dry fluidity, which is very beneficial for continuous feeding, and the distribution of glass fibers in the product is very uniform.

3) Excellent wet dispersibility and fluidity, easy to be impregnated by trees.

Application of chopped strands

Mainly used to strengthen thermoplastics. Because of its good cost performance, it is especially suitable for compounding with resins as fiber reinforcement materials for automobile, train and ship shells: used for high temperature resistant needle-punched felt, automobile sound-absorbing sheet, hot-rolled steel, etc. Its products are widely used in automobile, construction, aviation daily necessities and other fields. Typical products include auto parts, electronic and electrical products, and mechanical products.

It can also be used to strengthen the inorganic fiber with excellent anti-seepage and crack resistance of mortar concrete. It is also a very competitive product for reinforcing mortar concrete such as polyester fiber and lignin fiber. It can also improve the high temperature stability and low temperature crack resistance of asphalt concrete. performance and fatigue resistance, and prolong the service life of road surfaces.
