Product Description
Pre-oxidized fiber sealing strips are a kind of sealing material mainly made from pre-oxidized fibers, possessing a variety of excellent properties. The following is a specific introduction:
Properties
- Outstanding Flame Retardant Performance: Pre-oxidized fibers themselves have a high Limiting Oxygen Index, generally greater than 45%, belonging to flame-retardant materials. When burning, the fibers do not melt, do not soften and shrink, and there is no molten drip. They directly turn into carbonization without generating open flames or spark splashing, which can effectively prevent the spread of flames and greatly improve the safety during the use process. They are especially suitable for places with high requirements for fire prevention.
- Good High-Temperature Resistance: Pre-oxidized fibers have undergone special treatment to form a stable molecular structure, enabling them to withstand relatively high temperatures. The long-term service temperature can reach 300 °C, and the instantaneous high-temperature resistance can reach 1000 °C. They can still maintain stable performance in a high-temperature environment and are not prone to deformation, shrinkage and other situations, which can meet the sealing requirements in high-temperature scenarios such as the edges of ovens and the outsides of high-temperature furnaces.
- Strong Chemical Stability: They have relatively strong tolerance to chemical substances such as acids and alkalis. The chemical bond structure is stable, and they are not easily damaged by chemical reactions when in contact with chemical reagents. Therefore, in the sealing applications in the chemical and environmental protection industries, even when in contact with various chemical solutions and gases, they can maintain their own performance and ensure long-term and stable sealing effects.
- Reliable Mechanical Properties: They have relatively high elongation at break and tensile strength, can withstand certain mechanical forces such as tension and bending, and are not easily broken or damaged. Meanwhile, their tear resistance is also relatively strong. When subjected to external tearing forces, they can maintain the integrity of the structure and can be used in sealing parts that require a certain degree of strength.
- Excellent Heat Insulation Performance: Due to the low thermal conductivity and good thermal stability, pre-oxidized fiber sealing strips can effectively block heat transfer. They can be applied in fields such as building insulation and industrial heat insulation. For example, as sealing materials for the external wall insulation system of buildings, they can reduce the exchange of heat between the inside and outside of the buildings and reduce the energy consumption of the buildings. In terms of the heat insulation of industrial high-temperature equipment, they can also protect the surrounding equipment and personnel from the impact of high temperatures.
- Good Processability: They are easy to be processed into various shapes and sizes. They can be made into sealing products for different purposes through processing methods such as cutting, sewing and compounding to meet diverse market demands. For example, they can be cut into appropriate shapes for making sealing strips along the edges of ovens, door and window sealing strips, etc.
- Environmental Protection Characteristics: If the raw material of pre-oxidized fibers is renewable polyacrylonitrile fibers, then from the perspective of raw materials, pre-oxidized fiber sealing strips have a certain degree of environmental protection. Moreover, after the end of the product's service life, they can be processed through recycling and other means to reduce environmental pollution.
Applications
- Industrial Field: They are widely used in high-temperature industrial filtration equipment, aerospace heat insulation components, the chemical and environmental protection industries...
