The first paragraph (core: basic physical properties, structural support and processing stability for high-temperature scenarios)
This pre-oxidized fiber nonwoven fabric, with a basis weight of 470±10% g/㎡ and a thickness of 3.7±0.2 mm, creates a thick and dense substrate, suitable for automated processing such as cutting and molding in production workshops for high-temperature protection and industrial sealing products. During processing, the material is less prone to deformation and uneven thickness, maintaining the required three-dimensional structure of the finished product and providing a reliable base for subsequent functional layer lamination. Finished products produced in such settings (high-temperature protection product factories, industrial sealing component processing plants) can be used in industrial furnace sealing, fireproof and heat-insulating gaskets, fire protection linings, etc., ensuring the structural regularity of the finished product from the substrate layer and preventing collapse and deformation after long-term high-temperature use.
Customization: Customized materials: All properties of the material, as well as indicators such as basis weight and thickness, can be customized to meet specific needs.
Leveraging its longitudinal tensile strength of ≥400 N/5cm and transverse tensile strength of ≥200 N/5cm, this pre-oxidized filament nonwoven fabric provides robust mechanical support for finished products. In the molding process of industrial sealing components, its high tensile strength withstands equipment pressure and assembly stress, making it resistant to tearing and damage. In fire protection applications, it resists external pulling and friction, ensuring the integrity of the protective structure. The finished product is suitable for applications such as sealing high-temperature industrial equipment and providing insulation layers for fire suits, maintaining stable structure and function under complex working conditions.
With longitudinal elongation at break ≥40% and transverse elongation at break ≥140%, this pre-oxidized fiber nonwoven fabric exhibits excellent deformation adaptability: during the production of fireproof and heat-insulating liners, the material can be appropriately stretched to conform to the curved surfaces of equipment or the contours of the human body, avoiding problems such as loose adhesion, wrinkling, and cracking due to excessive rigidity; under high-temperature conditions, it can buffer stress changes caused by thermal expansion and contraction, maintaining a tight bond with the substrate. This type of finished product is suitable for applications such as heat insulation for irregularly shaped industrial equipment and protective linings for human bodies, improving sealing and protective effects in high-temperature environments.
The fourth section (Core: High Temperature Resistance and Flame Retardant Properties, Building a Solid Safety Barrier in Extreme Environments)
describes this pre-oxidized fiber nonwoven fabric as having a high temperature resistance of 350-450℃ and a flame-retardant/fire-resistant Class A safety characteristic, perfectly matching the needs of extreme high temperature and fire protection scenarios. In the assembly of finished products in high-temperature protective equipment factories, it serves as a core insulation layer, maintaining structural stability and delaying the spread of flames under high-temperature conditions. In industrial furnaces, fire rescue, and other scenarios, it effectively blocks heat transfer, reducing the risk of fire and high-temperature burns. The finished product is suitable for diverse scenarios such as industrial high-temperature protection, fire-fighting equipment, and building fireproof sealing, helping manufacturers create high-safety-level protective products and expand into the high-end industrial and emergency protection market.
