About Amatex

Since 1950, Amatex Corporation is an industry leader in the design and manufacturing of industrial textile products for high temperature applications. We make both broad woven cloth and narrow products. Standard fiberglass products are used for temperatures to 1000 ºF; basalt products are used for temperatures to 1200 ºF; silica fabrics are used for temperatures up to 1800 ºF. Industries include welding, power, chemical, automotive, marine, and hearth.


Amatex has been manufacturing textile products for high temperature applications for over 70 years. Manufacturing locations include Norristown PA, Laconia NH, Juarez MX, as well as distribution warehouses throughout the country.

Our Innovation

Amatex Corporation is an innovative supplier of Thermoglass ™ fiberglass and silica woven fabrics, tapes, tubing, braids, wicks, rope, and knitted sleeving. In the design and engineering of Amatex textile products, the requirements of their end uses determine the yarn size and construction, weave pattern, fabric construction, and fabric finish. The filament diameter, count, twist, and the ply of the yarn all affect the thickness, weight, pliability, surface texture, and tensile strength of the fabric. The weave pattern controls its stability and directional strength. The fabric construction influences strength, pliability, and appearance. And finally, fabric finish stabilizes the weave and may improve its resistance to high temperature, moisture, flame, or abrasion.

Amatex was the first US firm to use DREF friction spinning as a means to produce yarns with a fiberglass core and fiber wraps that include fiberglass in combination with other high temperature fibers. Throughout the years, Amatex has purposefully modified standard textile equipment in order to make quality fabrics with hard-to-process fibers. In addition to DREF yarn spinning,Amatex is skilled at fiberglass yarn texturing and at the inclusion of metallic filament wires into its varied yarn constructions. Upon request, all of these yarns may be fabricated in widths from 3/16 inch up to 60 inches and beyond.

Amatex offers a variety of high temperature finishes for its range of fiberglass and silica fabrics. Finishing options include heat treating, Vertex™ treatment to increase temperature resistance, durable water repellent finishes, rewettable finishes, adhesives, silicone treatments, acrylic coating, neoprene coating, vinyl coating, and laminated products including foil and film aluminization.

Throughout the second half of the last century and up to now, Amatex has remained strongly committed to development, service, and quality to meet the changing needs of our valued customers. Expect nothing less!
