Polyimide (PI)
Engineering materials experts for extreme environments, renowned for exceptional high-temperature performance, outstanding mechanical strength, and superior electrical insulation properties. They play a critical role in industry, from high-temperature fuel cells to displays and various military applications, addressing diverse extreme-environment requirements.
FacingHigh-temperature failure, insufficient insulation, environmental corrosionWhen facing such challenges, you need more than just a material supplier—you need a technical partner who truly understands your needs.
Chengxin Seal KingSpecializing in polyimide (PI) materials for over 20 years,We understand the unique challenges of every industry. From aerospace and defense to consumer electronics, from new energy to industrial equipment, we provide not only world-class PI materials but also comprehensive technical support and customized solutions.
Let us start from the very source of materials to craft products that are truly reliable and stand the test of time.
Are you facing these challenges?
- Equipment frequently malfunctions under high temperatures, with maintenance costs continuing to rise.
- Traditional materials cannot meet the temperature resistance specifications of the new product.
- Material thermal deformation leads to unstable production yield rates.
- Frequent part replacements impact delivery times and production efficiency.
These issues not only erode profits but also potentially undermine product competitiveness. In industries such as aerospace, automotive, and energy, a material's high-temperature resistance directly determines product reliability and market standing.
In the electronics, power, and telecommunications industries, the performance of insulating materials directly impacts equipment safety and personnel protection. Traditional insulating materials gradually degrade in dielectric properties during prolonged use or exposure to high-temperature environments, increasing the risk of short circuits and electrical leakage.
- High-voltage equipment requires more reliable insulation protection.
- Miniaturized products demand thinner insulation layers without compromising performance.
- Insulation materials are prone to aging and failure under harsh conditions.
- The selection of materials compliant with international safety regulations is limited.
PI materials deliver the industry's highest level of electrical insulation performance, ensuring your products operate safely under any conditions.
For equipment requiring long-term exposure to outdoor or harsh environments, the weather resistance of materials determines the product's lifecycle cost. Environmental factors such as ultraviolet radiation, ozone, chemicals, and temperature/humidity fluctuations continuously attack material structures, leading to diminished mechanical properties, appearance degradation, and even structural failure.
