Temperature-resistant fireproof silicone cloth used for high-temperature material conveyor belt lining

Aramid composite silicone fabric is typically made by using aramid woven fabric or non-woven fabric as the reinforcing framework, coated or calendered with a layer of silicone rubber on both sides, and then compounded through a high-temperature vulcanization process.

The key feature of aramid composite silicone fabric lies in its stable and synergistic performance across an extremely wide temperature range (-60°C to 300°C). This not only means it can withstand extreme high and low temperatures, but more importantly, the material maintains reliable flexibility and dimensional stability throughout the entire temperature range, laying the foundation for dynamic applications.

On this solid foundation, it demonstrates excellent mechanical and protective performance combining rigidity and flexibility. The internal aramid framework provides metal-like high-strength support, while the outer silicone layer significantly enhances surface tear resistance, wear resistance, and overall flexibility, as well as puncture resistance, achieving robust protection in a lightweight form.

The performance dimension is further expanded as the silicone layer endows the material with comprehensive dynamic sealing and isolation barrier functions. It can effectively block the intrusion of water vapor, dust, oils, and various chemical media, and can also achieve self-cleaning ability through hydrophobic treatment, thereby maintaining long-lasting protective integrity in harsh environments.

Aramid composite silicone fabric maintains long-term reliability and inherent safety under harsh conditions. Its outstanding ozone resistance, aging resistance, and fatigue resistance (such as over 2 million folding fatigue cycles) ensure an ultra-long service life. At the same time, its environmentally friendly characteristics of low smoke and non-toxicity during combustion eliminate secondary hazards, integrating high-performance protection with absolute safety for personnel and the environment.

Applications of aramid composite silicone fabric:

1. High-temperature industrial protection and sealing

Aramid composite silicone fabric features lightweight, insulation, high-temperature resistance, environmental friendliness, and excellent sealing properties, simplifying design and maintenance with multifunctional material.

Welding protective curtains/shields: Directly block welding sparks and slag; its silicone surface resists slag adhesion, and its flame-retardant properties prevent sparks from igniting.

Heat treatment equipment insulation covers: Wrapped around furnace bodies or high-temperature pipes to effectively reduce heat radiation loss and improve the working environment; its flexibility facilitates installation on complex structures.

High-temperature pipe wrapping materials: Not only provide insulation but also excellent sealing to prevent moisture and corrosion, extending pipe lifespan.

Non-metallic compensators (expansion joints): Utilize the material's flexibility and temperature resistance to absorb displacement and vibration caused by thermal expansion and contraction of pipes while maintaining sealing.

Conveyor belt liners: Used in high-temperature material transport lines to protect conveyor belts from heat damage and reduce material adhesion.

2. Special safety protection

Aramid composite silicone fabric integrates physical protection (cut resistance), thermal protection (flame retardant and insulation), and chemical protection (liquid-repellent sealing) into a single material layer, achieving lightweight and functional integration of protective equipment.

Fire blankets/extinguishing blankets: Compared to traditional fiberglass blankets, it is more flexible and stronger, and the silicone surface layer resists chemical corrosion, suitable for high-risk environments such as laboratories and chemical plants.

High-performance protective clothing lining: Serves as a key lining layer for cut resistance, protection against high-temperature metal slag splashes, or chemical protective clothing. Aramid provides cut and tear resistance, while the silicone layer acts as a dense barrier against liquid chemicals or high-temperature penetration.

Special occupational equipment: Such as aprons and sleeves for industries like metallurgy and glass manufacturing that require resistance to high-temperature baking and occasional contact with molten materials.

3. High-end equipment and transportation

The lightweight, high strength, and fatigue resistance of aramid composite silicone fabric directly contribute to weight reduction, efficiency improvement, and reduced lifecycle maintenance costs of equipment.

Flexible connecting components: Such as soft connecting pipes in engine systems and ventilation ducts (especially transition ducts for locomotive traction motors), capable of compensating installation errors, absorbing equipment vibration and thermal displacement, with temperature resistance ensuring long-term operation under high-temperature airflow.

Equipment protective covers: Provide lightweight insulation, dustproof, and moisture-proof covers for precision instruments or pipelines, especially advantageous in compact spaces like ship cabins or spacecraft.

Insulation and soundproofing components: Used for cabin partition padding or wiring harness wrapping with high fire protection requirements, combining electrical insulation and flame retardant properties.

4. Electrical and new energy

Motors and transformers: Used as slot insulation, phase insulation, or overall padding, providing long-term stable electrical insulation and high-temperature resistance in compact spaces.

Power battery packs: One of the fastest-growing applications currently. Used as thermal insulation and flame-retardant separators between battery cells, module end plate padding, or inner lining of battery pack covers. Its critical role is to effectively delay or block heat spread to adjacent cells during thermal runaway of individual cells, buying crucial time for system safety warnings and handling.

Charging facilities: Used for insulation protection of high-voltage components inside charging piles.
