Heat-Resistant Fabric Names: Kevlar, Nomex & More

What is the heat-resistant fabric called?

“Heat-resistant fabric” is a broad label, not one single material. Depending on the temperature range and how the textile is used (gloves, sleeves, welding blankets, or oven mitt liners), several fabrics may be called heat-resistant. The most common names you’ll see are aramid fabrics like Kevlar® or Nomex®, fiberglass cloth, carbon felt, and silica (high-silica) fabric. Each one handles heat differently and also varies in flexibility, comfort, and durability.

Answer

The heat-resistant fabric most often referred to by name is aramid fabric—typically Kevlar® or Nomex®. These materials are designed to handle high heat exposure and resist melting, which makes them popular in protective apparel and heat shields. Another widely used heat-resistant textile is fiberglass fabric, often chosen for very high temperatures but typically less comfortable against skin unless it’s lined.

For everyday kitchen use, many “heat-resistant” products rely on layered construction rather than a single fabric. For example, a mitt may combine an outer layer that’s heat- and water-resistant with an inner liner that adds insulation and comfort. Silicone-coated oven mitts are a common solution because silicone helps block heat transfer and improves grip while also resisting steam and splashes.

If you’re choosing something for cooking and baking, pay attention to the product’s stated temperature rating, the length of coverage (especially at the wrist and forearm), and whether it’s designed for dry heat, steam, or both. For a practical look at coverage and materials—especially longer designs that help protect the wrist—see this guide to extended silicone oven mitts with wrist protection.

For Heat-Resistant Fabric Names: Kevlar, Nomex & More, the best answer depends on fit, material, care instructions, and how the product will be used day to day.

FAQ

What material is best for oven mitts: silicone or cotton?

Silicone is typically better for grip and for handling steam or splashes, while cotton can feel softer but may absorb moisture and heat faster. Many high-performing mitts combine silicone on the outside with insulating layers inside for comfort and protection.
