1. Basic Material Properties and Structural Advantages
Polyimide P84 is a high-performance fiber material. After modification by adding a mesh structure, it can significantly enhance the mechanical strength and tensile resistance of the material, while endowing it with excellent non-combustible properties, thus strengthening the practical reliability of the material from the structural perspective.
2. Outstanding High-Temperature Resistance
Wide Temperature Adaptation Range
: The short-term operating temperature can reach 280℃, and the long-term stable operating temperature ranges from 260℃ to 300℃, which can meet the continuous operation requirements under high-temperature working conditions;
Excellent High-Temperature Stability
: The initial decomposition temperature is as high as 569℃, and only carbonization occurs in high-temperature environments without melting and dripping, avoiding secondary risks caused by high-temperature molten substances;
Low-Smoke Environmental Advantage
: The smoke density is only 1/200 of the value specified in China's aviation standards, which can greatly reduce smoke hazards in high-temperature scenarios and improve operational safety.
3. Excellent Weather Resistance and Chemical Corrosion Resistance
Strong Thermal Stability
: It can maintain stable physical and chemical properties in continuous high-temperature environments without obvious aging or performance degradation;
Acid-Alkali Resistance and Anti-Aging Ability
: It has certain acid-alkali resistance, oxidation resistance and hydrolysis resistance, with excellent chemical stability;
Wide Applicable Acid-Alkali Range
: It has good filtering performance for acidic waste gas and alkaline dust, and can be stably used in acid-alkali environments with a pH value of 2-12, adapting to various complex working conditions.
4. Advantages in Practical Performance and Service Life
Wear Resistance and Pressure Characteristics
: It has good wear resistance and a small pressure difference during operation, which can reduce losses caused by friction or pressure fluctuations;
High Dimensional Stability
: During long-term use and temperature changes, the size remains stable without obvious shrinkage or deformation, ensuring the matching accuracy of equipment;
Extended Service Life
: Combined with the comprehensive advantages of mechanical strength, high-temperature resistance and corrosion resistance, it greatly extends the service life of the material under harsh working conditions and reduces the frequency of replacement and costs.
5. Excellent Flame Retardancy and Low-Smoke Characteristics
The limiting oxygen index (LOI) reaches 38%, far exceeding the basic standard for flame-retardant materials (LOI ≥ 26%), and it has self-extinguishing properties (it can extinguish itself after being away from the fire source); at the same time, the smoke emission rate is low. It is especially suitable for scenarios with strict requirements on flame retardancy, such as flame-retardant protective products and high-temperature fire-proof filtration equipment.
