Ironclad HeatWorx® Reinforced HW4 Gloves Features
The Ironclad HeatWorx® Reinforced HW4 glove delivers intermittent contact-heat protection up to 450°F using a DuPont™ Kevlar® blended shell, inner liner, and stitching. Patented Hotshield® palm technology holds dexterity while adding cut, abrasion, and shrink resistance. An extended gauntlet cuff guards the wrist and lower forearm during hot-handling tasks.
Most heat gloves advertise a temperature but hide the underlying test data, leaving safety officers unable to match the glove to a hazard assessment. This model resolves that gap with documented ANSI/ASTM F1060 Level 5 heat performance, ANSI 105 A2 cut resistance, and an EN388 3222 mechanical rating. Buyers verify suitability before deployment.
Maintenance stays simple for high-turnover shops. These gloves are oil-repellent, water-repellent, and 100% machine washable, so crews launder rather than discard them. Reinforced Hotshield® zones protect wear points, extending service life across welding, fabrication, and hi-temp automotive cycles.

Laboratory and Industrial Applications
Materials labs, foundry assay stations, and pilot-scale fabrication shops use the HW4 for handling heated crucibles, hot stock, and freshly welded assemblies. The Kevlar® liner adds cut protection when manipulating sheet edges or removing parts from furnaces, where bare or single-purpose gloves fail.
Maintenance and QA teams deploy these in hi-temp automotive and equipment-servicing bays. Engine work, exhaust handling, and machinery cool-down inspections all benefit from a glove that resists heat while retaining the dexterity needed for fasteners and small components.

Frequently Asked Questions
Is the 450°F rating for continuous or intermittent contact?
The 450°F figure reflects intermittent contact heat under ANSI/ASTM F1060 Level 5. These gloves are not rated for sustained grip on objects at that temperature; use them for brief handling of hot stock.
What cut level do these gloves provide?
HW4 gloves carry an ANSI 105 A2 cut rating with an EN388 3222 mechanical score, suitable for moderate cut hazards alongside heat exposure in fabrication settings.
Can these gloves be laundered for reuse?
Yes. The Kevlar® construction is 100% machine washable and oil/water repellent, allowing repeated cleaning cycles without significant degradation of heat or cut performance.
