Different product processes, the temperature resistance is also different, there are 100 degrees, 300 degrees, 1000 degrees and so on. High-temperature resins have the characteristics of aging resistance, insulation, waterproof, etc. Usually, high-temperature resins include polyimide PI, phenolic resins, bismaleimide (BMI), silicone resins, etc. The temperature resistance of polyimide PI can reach up to 400 degrees, characterized by high viscosity and high processing performance. Polyimide PI can withstand temperatures up to 400 degrees, characterized by high viscosity and poor processing performance. Phenolic resin has a softening temperature of about 100 degrees Celsius, with a high residual carbon rate. Bismaleimide molding temperature of about 180 degrees Celsius, its decomposition temperature is greater than 420 degrees Celsius, excellent mechanical properties, good toughness. The thermal decomposition temperature of silicone resin is about 380 degrees Celsius, and the weathering resistance of this resin is greater than that of general resins.
