fiberglass yarns can be braided to produce tubular structures. The flexibility of the braid structure, as well as the mechanical, thermal and electrical characteristics of glass, make braided fiberglass ideal for many products.
A circular braiding machine is composed of two rotating sets of bobbins on which glass filament yarns have been wound. One set runs clockwise; the other runs counterclockwise around the center of the machine along a defined path. The bobbins of the two sets pass alternatively inside and outside along the path, forming the tubular braid structure. Its width is determined by the take-up speed of the braiding machine. In some applications, the tubular sleeve can be braided on a core because the braiding structure can easily conform to any complex shape. The resulting product is called rope. The rubbing forces are high during braiding, therefore, plied yarns are often used to avoid break and fuzz accumulation.
Tension control systems ensure that the fiberglass strands are appropriately tensioned during the braiding process. Consistent tension is important for maintaining uniformity and quality in the braided structure. Furthermore, the braids can undergo additional treatments such as coating, impregnation, and partial or full heat cleaning to impart specific characteristics desired by the end user. The final product is commonly called sleeving“.
The specific details and parameters of the fiberglass braiding process can vary based on the machine design, application, and desired product specifications.
Heat resistant sleeves are used to cover cables, wires, and hoses to protect them from heat and flame or to provide electrical insulation. Heat resistant sleeves also protect from oil, water, and grease around fuel lines and hydraulic equipment in industrial applications. In addition to high temperature industrial environments, heat resistant sleeves are commonly used for thermal management in the automotive aftermarket.
HardTape offers fiberglass sleeves , ceramic sleeves in a range of diameters. We can also manufacture aluminized sleeving and coated heat resistant sleeves for custom orders.
Woven from continuous filament ceramic oxide fibers, the ceramic Sleeves are the most temperature resistant sleeves that HardTape offers. These heat resistant sleeves can withstand continuous operating temperatures up to 2000F / 1095C.
Woven from continuous filament DE Glass yarns, fiberglass sleeves can withstand temperatures up to 1000F/540C. These heat resistant sleeves can also be treated with a vermiculite coating for improved temperature resistance and abrasion resistance.
HardTape Silicone Coated Fiberglass sleeving is engineered from E-glass fiber that is knitted and braided into a flexible tubing that is coated with a high-performance silicone coating for improved abrasion and chemical resistance. our Silicone Coated Fiberglass sleeving can be used for operating conditions up to 500°F (260°C).
Two grades of HardTape Silicone Coated Fiberglass sleeving are available: Industrial Grade (S-GSI) sleeving is knitted while the Aerospace Grade (S-GSA) sleeving is braided with a thicker wall thickness to meet Aerospace insulation requirements. Standard colors are iron oxide red and grey. Additional colors are available for specific grades.
HardTape Silica Sleeving is used for high temperature applications requiring outstanding thermal protection. It is made with a braided flexible tube of amorphous silica fiber with a silicon dioxide content over 96%. our Silica Sleeving is specifically designed for operating conditions up to 1800°F (982°C). A proprietary surface finish is applied to all our Silica sleeving to improve handling properties.
Diameters from 12.7mm to 76.2mm.
