Product Advantages
  • Outstanding Thermal Resistance: Features an extremely wide operating temperature range. Suitable for long-term use from -269°C to +260°C, and capable of withstanding short-term exposure up to 400°C without melting or deformation.
  • Excellent Electrical Insulation: High dielectric strength effectively blocks electrical current, preventing leakage and short circuits. Ideal for high-voltage applications or insulation protection of miniature electronic components.
  • Low Outgassing: Exhibits minimal volatile release under vacuum conditions, preventing contamination of semiconductor process chambers and meeting high-cleanliness standards.
  • Superior Mechanical Strength: Tough, wear-resistant, and creep-resistant material with good elastic recovery after compression, making it suitable as a cushioning interface in precision machinery.
  • Chemical Resistance: Offers good resistance to most organic solvents, acids, and alkalis, suitable for complex chemical processing environments.
