Flame-retardant modacrylic fiber nonwoven cloth

The Huamaotek 470gsm Flame Retardant Needle-Punched Nonwoven Fabric (commonly referred to as fireproof felt or insulation batting) is a high-performance industrial textile engineered for applications requiring stringent fire safety standards. With a substantial weight of 470 grams per square meter, this fabric provides superior thickness, density, and durability compared to standard lightweight nonwovens.

Manufactured using advanced needle-punching technology, this fabric creates a stable three-dimensional structure that effectively combines fire resistance with physical resilience.

Key Features & Functions

• Flame Retardant & Self-Extinguishing: Treated with or made from modified fibers (such as flame-retardant polyester), the fabric stops burning once the ignition source is removed. It resists melting and dripping, preventing secondary fire hazards.

• High Thermal Insulation: The dense fiber matrix traps air, providing an excellent barrier against heat transfer, protecting components and surfaces from high temperatures.

• Superior Filtration: The porous needle-punched structure is highly effective at trapping dust, particulates, and airborne pollutants.

• Physical Protection: The 470gsm weight offers robust cushioning and impact resistance, making it suitable for padding and protective layering.

• Acoustic Dampening: The fibrous structure helps absorb sound waves, contributing to noise reduction in enclosed spaces.

Technical Specifications

Applications

Thanks to its high weight and fire-resistant properties, this material is widely used across various industries:

• Automotive Industry:

  • Engine compartment hood liners for heat insulation.

  • Firewall insulation to protect the cabin.

  • Interior trim backing and carpet underlayment requiring flame resistance.

• Furniture & Upholstery:

  • Fire barrier layer in mattresses and sofas.

  • Stuffing and padding that combines comfort with safety.

• Industrial & Welding:

  • Welding blankets and spark protection mats.

  • Heat shields for machinery and pipelines.

• HVAC & Appliances:

  • Insulation lining in air conditioners, heaters, and ovens.

  • Fireproof seals and gaskets.

• Construction & Transportation:

  • Thermal and acoustic insulation in walls, floors, and ceilings of trains, ships, and RVs.

  • Fire stop padding in building envelopes.

Advantages

• ✅ Safer Handling (vs. Fiberglass): Non-irritating to the skin and free from respirable particles, offering a safer alternative to fiberglass insulation.

• ✅ Cost-Effective Solution: Provides reliable flame retardancy at a lower cost compared to high-end materials like Aramid (Nomex®) or Pre-oxidized fibers.

• ✅ Excellent Processability: Can be easily cut, die-cut, slit, and sewn without fraying easily, allowing for custom shapes and sizes.

• ✅ Environmentally Friendly: The needle-punch process is mechanical and does not require chemical binders or adhesives, reducing off-gassing and maintaining stability under heat.

• ✅ High Dimensional Stability: Maintains structure and thickness under pressure and heat, ensuring long-lasting protection.
