HEAT-MX

FR-MX

Flame-retardant padded insulation with high thermal efficiency for demanding cold-weather workwear and gear.

FR-MX is a padded non-woven thermal insulation engineered to support anti-flammability requirements in finished products while delivering high warmth efficiency through HEAT-MX thermal design. It is intended for apparel, gloves, footwear, and textile systems where protection, comfort, and reliable winter warmth need to coexist.

Key benefits of HEAT-MX™ FR-MX

Flame-retardant insulation layer
FR-MX is engineered for applications where anti-flammability performance is required in the finished system, supporting protection-focused apparel and gear designs.
High warmth efficiency
Built on HEAT-MX’s proprietary thermal platform to trap and retain body heat efficiently, helping brands reach warmth targets without excessive bulk.
Comfort in real weather
Designed to support comfort through moisture management and warm-even-when-damp performance—important for active work and variable winter exposure.
Integration-friendly for apparel, gloves & footwear
A padded insulation format that fits common manufacturing flows (patterning, stitching, quilting/lamination strategies), enabling practical adoption for industrial and consumer products.

Ideal applications

FR-MX is designed for cold-weather products that need both warmth and FR-oriented protection in the final construction.

For application-specific guidance (e.g., gloves, footwear, workwear), please see our Application pages or contact our technical team.

Performance & care

FR-MX combines flame-retardant behavior with HEAT-MX insulation performance features (warmth retention, moisture control, and day-to-day maintainability). Specific outcomes depend on the product code and full construction.

Flame retardancy & compliance considerations

FR insulation layer
Engineered to support anti-flammability requirements in apparel, gloves, footwear, and similar product systems.
Material-level test references
FR-MX reports results under standards such as ASTM D6413, ISO 6941, and BS 5852 (see datasheet).
Critical note
FR-MX test results do not represent the final product’s anti-flammability performance. Finished goods must be validated by the brand/manufacturer to the required specification.
LRTD™ thermal platform
Optimized heat retention for cold exposure.
Cold-air resistance / warm-air retention
Supports perceived warmth in wind and cold conditions.
Lightweight insulation strategy
Designed for warmth without unnecessary mass.
Moisture management
Supports comfort in active use and variable humidity.
Warm even when damp
Maintains warmth more reliably when exposed to moisture in real conditions.
Easy maintenance
Finished goods made with HEAT-MX insulation may be home laundered and/or dry cleaned depending on the brand care label and construction.
Always follow
the finished-goods care instructions and code-specific datasheet guidance.

Actual performance and care instructions depend on the specific FR-MX article and garment construction. Always follow the care label and datasheet guidance.

Sustainability & circularity options

FR-MX can be specified with HEAT-MX environmental and social innovation options depending on the product code and supply configuration. Availability is program-dependent—confirm during specification.

Clean Recycling Initiative™ compatibility

Selected programs may align with HEAT-MX Clean Recycling Initiative™ principles to reduce industrial waste and improve material flows.

Microplastic reduction (NMF™ platform)

HEAT-MX’s NMF™ innovation platform targets minimizing microplastic contamination, supporting more responsible textile lifecycles.

Chemical-free performance approach

Certain HEAT-MX performance platforms emphasize structure-driven performance to reduce reliance on added performance chemicals (option and code dependent).

Care-related impact reduction

When paired with appropriate care instructions and constructions, easier maintenance pathways can help reduce long-term impact versus more complex care routines.

Not all sustainability options apply to every FR-MX configuration. Confirm code-specific availability with your HEAT-MX representative.

Awards & industry recognition

FR-MX is part of the HEAT-MX insulation platform recognized by the ISPO Top of Innovation Awards, highlighting HEAT-MX’s innovation in thermal insulation performance and responsible technology development.
