We offer two types: one with excellent insulation properties and heat resistance, and another with excellent thermal insulation properties.
"Polyimide coating" is a dry lubrication coating that offers heat resistance and insulation. There are two types: "Type ST," which excels in insulation properties, heat resistance, and wear resistance, and "Type BP," which has excellent heat resistance and insulation properties due to its porous structure. "Type ST" has excellent chemical resistance against organic solvents, gasoline, automotive oils, alkalis, acids, and more. "Type BP" features breathability and liquid permeability, providing outstanding insulation due to its porous nature. [Features] ■ Supports high-temperature processes up to 500°C (Type ST) ■ Highest level of mechanical properties among polymers (Type ST) ■ Thermal expansion is close to that of metals, providing excellent adhesion (Type ST) ■ Excellent heat resistance (approximately 300°C) (Type BP) *For more details, please refer to the PDF document or feel free to contact us.
