CAS NO:62929-02-6 Polyimide Resin

The core performance advantages include extremely high heat resistance, stability across the entire temperature range, high strength and rigidity with precise dimensions, low loss and high insulation at high frequencies, resistance to strong corrosion and self-extinguishing fire retardancy. All these features are combined and suitable for extreme working conditions, making them the core characteristics of high-end engineering materials.

1. Thermal runaway protection and heat spread interruption
2. Lightweighting and structural compatibility
3. Insulation fire resistance and chemical stability

1. Corrosion resistance and interface protection
2. Hydrophobicity and anti-blocking as well as structural stability
3. Low contact resistance and conductive compatibility
4. Cost and process compatibility

It is because the three core characteristics of high-frequency and low-loss electrical performance, stable flexibility and rigidity across the entire temperature range, and extremely high-temperature resistance in thermal properties perfectly match the precision, high-frequency, miniaturization, and resistance to harsh conditions requirements of these two types of devices. At the same time, it also has additional advantages such as lightweight, corrosion-resistant insulation, and stable size, which perfectly solve the performance shortcomings of traditional substrates (epoxy resin, polyester) in high-frequency, flexible, and high-temperature conditions.

The low thermal expansion coefficient of polyimide resin (CTE ≈ 20 - 30 ppm/℃) achieves dimensional stability of precision components under high and low temperature conditions through three effects: matching the thermal expansion characteristics of the substrate, suppressing thermal deformation, and maintaining structural rigidity. It eliminates dimensional deviations under high and low temperature conditions at the molecular and structural levels, precisely ensuring the dimensional stability of precision components.
