Nomex® is often associated with moderate temperature applications designed to protect equipment and workers from heat and flame. That reputation is well earned, but it only captures part of how the material is used today. Industrial safety increasingly extends into technology, production lines, and infrastructure where Nomex® serves as a stable barrier against continuous heat, electrical energy, and ignition risks. Consequently, Nomex® Fabric, both coated and uncoated, not only provides protection for people, but also stabilizes the environments and processes in which they work.
Thermal Runaway Containment: Battery Bags and Pallet Covers
Lithium-ion batteries present a distinct challenge during storage and transportation. A failure in a single cell can trigger thermal runaway, releasing intense heat and initiating a self-sustaining reaction that escalates rapidly. Once underway, this process is difficult to stop, which shifts the emphasis from suppression to containment. ARMATEX® Nomex® Coated Fabrics are well suited to deliver thermal runaway containment. Battery bags and pallet covers fabricated with ARMATEX® Nomex® Coated Fabrics are engineered to withstand extreme temperatures while maintaining enclosure integrity. The goal is controlled isolation. By containing heat and flame at the pellet level, ARMATEX® Nomex® Coated Fabric used in battery bags helps prevent fire from spreading to nearby materials, equipment, or building structures. This localized containment slows escalation within the facility and provides vital time for personnel to execute established emergency procedures safely.
RobotCovers: Precision Protection for Automation
The use of automation in manufacturing operations can improve consistency and throughput, but can also introduce new exposure risks for equipment. Robots deployed in welding, casting, and finishing environments operate in close proximity to radiant heat, sparks, molten splash, and chemical overspray. Such exposure is continuous and cumulative, and, over time, it can degrade cables, sensors, and control components that are essential for precise, repeatable robotic motion.
THERMOPAK® Robot Covers manufactured with ARMATEX® SBN 13 Robotex provide a protective cover for high-value automation equipment in environments characterized by intense thermal exposure, hot particulates and incandescent debris, molten metal splatter, and aerosolized chemical exposure. Designed to shield sensitive components while preserving full range of motion, these robot covers allow robots to operate as intended without unnecessary restriction. The benefits of using THERMOPAK® Robot Covers extend beyond equipment longevity. When heat or contamination compromises electronics or sensing systems, machine behavior can become inconsistent or unpredictable. In automated environments where technicians must work near active systems, predictability is crucial. THERMOPAK® Robot Covers help reduce risk during maintenance, troubleshooting, and routine interaction between people and machines by stabilizing operating conditions around the robot, ensuring consistent, predictable system behavior through their resistance to heat, sparks, and chemical contamination.
Electrical Infrastructure: High-Dielectric Barriers
Electrical systems introduce hazards that often remain hidden until a failure occurs. In high-voltage environments, insulation integrity is critical for preventing arc events, short circuits, and secondary fires. If insulation degrades, even localized faults can escalate rapidly, posing risks to equipment, infrastructure, and personnel. HYTEX® Nomex® Textiles are widely used to form high-dielectric barriers that isolate energized conductors and withstand elevated operating temperatures. Within electrical cabinets, switchgear, and transformers, they are fabricated into phase barriers, insulating shrouds, and custom separators that manage heat build up and enable electrical separation. These components are designed to contain faults at their source, limiting the potential for propagation into larger incidents. In this role, HYTEX® Nomex® Textiles are able to preserve insulation performance under demanding operating conditions, supporting long-term system reliability and overall facility safety.
Industrial Filtration and Fluid Handling
High-temperature filtration is one of the most demanding continuous-duty applications for HYTEX® Nomex® Fabric (uncoated). In industries such as asphalt and cement production, exhaust temperatures frequently exceed the operating limits of standard filter media. Nomex® used in filter bags allow baghouse systems to operate at elevated temperatures, as well as enable effective particulate capture. This supports steady production while reducing premature media failure and unplanned downtime. HYTEX® Nomex® Fabric is also used in fluid handling systems where flexibility and heat resistance must work together to accommodate movement and thermal expansion without compromising system integrity. When combined with specialized coatings, Nomex Fabric can be used for expansion joints, ducting, and seals that accommodate vibration and temperature variation and also preserve airtight performance. These components help prevent leaks and secondary hazards in environments where pressure, vibration, and thermal cycling place continuous stress on seals and joints.
Specialty Fabrications
Not all high-temperature challenges exist on the production floor. ARMATEX® Nomex® Coated Fabrics are used in specialty fabricated components where heat exposure is intermittent and variable, but still consequential. Equipment covers used during transport and storage can benefit from ARMATEX® Nomex® Coated Fabrics when solar loading, exhaust proximity, or nearby heat sources generate localized temperature spikes that conventional materials cannot tolerate. Aerospace components are a common example. During transport, staging, or ground operations, sensitive equipment may be exposed to fluctuating temperatures, radiant heat, and environmental stressors that change rapidly over time. In these conditions, protective materials must perform reliably without becoming brittle, deforming, or degrading between exposure events. HYTEX® Nomex® Fabrics coated with various coatings can provide this margin of safety, allowing protective covers to maintain structural integrity and consistent performance across a wide range of operating and environmental conditions, from prolonged solar exposure on the tarmac to transient radiant heat during ground support operations.
Redefining Protection in the Modern Workplace
The expanding use of HYTEX® Nomex® Fabrics and ARMATEX® Nomex® Coated Fabrics beyond traditional industrial applications reflects a broader shift in how facilities approach safety. Battery containment, robotic protection, electrical insulation, filtration, and specialty covers all rely on the same principle: surrounding high-energy hazards with materials that remain stable under stress.
