Aramid 1313 grid fabric is used for automotive silicone hose clamps and high-temperature filtration
Jul 07,2025
Main characteristics of Aramid 1313 grid fabric:
① High temperature resistance
Long-term use temperature up to 220°C, short-term withstand 300°C (no shrinkage or embrittlement after several hours of exposure).
Starts to decompose above 370°C, carbonizes at 400°C, low thermal shrinkage.
② Flame retardancy and safety
Limiting Oxygen Index (LOI) >28%, belongs to flame-retardant fiber, does not burn or melt in air, and has self-extinguishing properties.
When encountering fire, the fabric surface thickens and enhances sealing, without cracking or releasing toxic gases.
③ Mechanical and chemical stability
High strength: The grid structure makes the warp and weft strength consistent, wear-resistant and tear-resistant, suitable for high-pressure environments.
Chemical corrosion resistance: Resistance to high-concentration inorganic acids, organic solvents, oils and hydrolysis.
Radiation resistance: Stable to α/β/χ rays and ultraviolet rays.
④ Functional adaptability
Adhesion performance: Strong bonding with silicone rubber and high-temperature rubber, it is an ideal material for hose reinforcement layers.
Lightweight: Weight range 60–360 g/㎡, combines high strength and low weight. [The above data comes from the internet and laboratory]
Main application fields of Aramid 1313 grid fabric:
(1) Automotive industry
High-pressure hose reinforcement layer: Used for turbocharger pipes, oil-resistant pipes, and cooling water pipes, withstanding high-temperature and high-pressure environments (such as engine peripheral pipelines).
Silicone hose reinforced fabric: The grid fabric is embedded in the silicone hose wall to improve pressure resistance and anti-deformation ability, suitable for large-diameter straight pipes.
(2) High-temperature filtration
Industrial flue gas filter bags: Used for dust removal of high-temperature flue gas in chemical plants, thermal power plants, and cement plants (temperature resistance above 260°C), with chemical corrosion resistance.
Hot air purification system: Hot air filtration for incinerators and arc furnaces, effectively intercepting dust and recovering precious metal particles.
(3) Safety protection equipment
Firefighting and industrial protective clothing: Blended grid fabric (weight 135–350 g/㎡) is used for fire suits and welding suits, which are flame-retardant and breathable.
Military uniforms and petrochemical work clothes: Enhance sealing to protect the human body when encountering fire.
(4) Special industrial materials
High-temperature sealing and gaskets: Used as heat insulation layers for aircraft fuel tanks and firewalls, or as high-temperature wire tube wrapping materials.
Composite material substrate: Composite with resin for bulletproof products and honeycomb structures (such as aerospace components).
