AVS textiles provide thermal protection to prevent heat from damaging equipment or to protect personnel from high temperature conditions.

Temperature Levels

Exposure temperature and length of time at that temperature should be taken into consideration when determining the type of textile required to provide optimum thermal protection.

Low to Moderate: 0 – 1000°F (-17.8° – 537°C)
Moderate to High: 1001 – 1300°F (538° – 704°C)
High to Very High: 1301 – 1800°F (705° – 982°C)
Extreme: >1800°F (> 982°C)

Thermal Protection Types

AVS Industries manufactures the following types of textiles in various weights, widths, thicknesses, and/or diameters to meet specific end use requirements:

Fabrics: Fiberglass, Silica and Wire Inserted Ceramic
Insulation: Silica
Sewing Threads: Fiberglass, Kevlar, Metallized and Quartz
Tapes: Aluminized Fiberglass and Silica (with or without PSA Backing)
Ropes: Twisted and Braided Silica Ropes
Sleeving: Silica and Fiberglass

AVS Industries develops and manufactures a diverse portfolio of high temperature fabrics to meet all types industrial end-use applications. Many of our fabrics are engineered with very specific properties to enhance product handling or thermal performance.

Fiberglass Fabrics (E-Glass)

Manufactured from premium grade E-Glass fiberglass fabric with a plain weave construction. Fabric is typically heat treated to remove residual sizing additives used during the weaving process.

AVShield™ Mid-Silica Fabrics

AVShield™ Mid-Silica Fabrics will not burn through when exposed to a Propane and MAPP gas torch for two minutes. Propane torch temperature is approximately 2000°F (1093°C). AVShield™ Mid-Silica Fabrics are an excellent choice for thermal protection for industrial and shipyard welding operations that involve sparks and light levels of molten splatter. AVShield™ Mid-Silica Fabrics can be fabricated into protective curtains and blankets.

Silica and Aluminized Fiberglass Slit Tapes

A Pressure Sensitive Adhesive (PSA) with release liner is laminated to AVSil® 84CH and 188CH satin weave silica fabrics and AVS FG ALUMF2025HTH aluminized fiberglass fabric. AVS slit tapes are typically used to protect electrical lines, hydraulic lines, and all types of tubing from radiant heat, welding sparks and splatter. The adhesive backing helps with installation on the item to be protected. Additional wire wrap may be required in continuous high temperature applications. The melt point of the adhesive system for the PSA backing is approximately 160°F (71°C) and is considered to be sacrificial. AVS can manufacture slit tapes from most of our high temperature fabrics. If you would prefer slit tapes with or without the PSA backing please give us a call to discuss your application.

Fiberglass Sleeving

AVS engineers this sleeving from a dense fiberglass sleeve and a thick coating of self-extinguishing high temperature silicone rubber that withstands 500°F (260°C) continuous exposure, and molten splash up to 2,000°F (1093°C).
