Textured glass yarn is one of the primary products in the B&W Fiberglass catalogue. It’s suitable for a wide variety of industries ranging from recreation to boating to aerospace thanks to its versatility and strength.

What is Textured Glass Yarn?
Textured glass yarn can be produced from many varieties of glass thread. The most commonly used is high-strength E-glass, although alternatives such as HR-glass, S-glass, and basalt fibers can also be used. Once processed, the yarn becomes suitable for an array of resins, polymers, and bitumen.

There are several different methods for producing texturized glass yarns. In some cases, an air nozzle can be used to bend glass filaments into entangled loops. In others, passage over a high-pressure air jet accomplishes the same goal. The purpose is to create a voluminous strand of glass filaments that is sufficiently texturized for further processing.

How is Texturized Glass Yarn Used?
Because of its inherent bulk, texturized glass has unparalleled insulative properties. It is also incredibly well suited for additional processing applications such as braiding, weaving, and warping; the “texture” of the yarn provides an additional layer of strength to the end-product.

Additionally, the texture of volumized glass makes it especially receptive to reinforcement. When coated with polymers and/or resins, textured glass provides higher strength-to-weight ratios than standalone glass strands. It’s possible to find texturized glass thread in everything from brake pads to tile backing to thermal insulation in industrial applications.

The Different Kinds of Texturized Glass
Textured glass strands can be made from a variety of materials. Certain materials imbue certain characteristics. For example, Silica textured yarns are extremely heat-resistant and can be used in a variety of high-tech applications. Aluminosilicate glass, conversely, contains no boron oxide and thus provides excellent thermal resistance and dialectic properties.

Not all glass threads can be made into textured glass yarn. Threads must measure a certain diameter to be compatible with the process, typically around 6 microns or more. In many instances, pure glass threads are blended with plastic fibers to create an ultra-strong end-product.
