  • Silicone-based polymers are hybrid polymers that combine the properties of organic and inorganic materials, boasting outstanding physical properties and stability that far surpass those of general organic polymers. They exhibit excellent performance in various characteristics such as heat resistance, chemical resistance, flexibility, electrical insulation, and light transmittance, making them widely used as key materials across many industries.
  • The most prominent characteristic is their superior heat resistance. Unlike general plastics or polymer materials, silicone-based polymers maintain their physical properties with minimal change even at high temperatures, allowing for stable use in environments ranging from 150℃ to over 300℃. Some specially formulated silicone materials can even retain their properties without decomposition at extreme temperatures above 500℃. This characteristic is crucial in industries exposed to high temperatures, such as semiconductors, automotive, and aerospace.
  • Additionally, they exhibit excellent chemical resistance, maintaining stable tolerance against various chemicals such as acids, alkalis, and organic solvents. As a result, they are widely used in chemical plants, pharmaceuticals, biotechnology, and semiconductor processes, where the risk of chemical corrosion is high.
  • Their light transmittance is also exceptional, offering transparency that allows a wide range of light from ultraviolet to infrared to pass through. This property is applied in LEDs, optical lenses, display materials, and other fields that demand high transparency, further enhancing the value of silicone-based polymers.
  • Silicone-based polymers also provide outstanding electrical insulation. They maintain stable insulating properties even in high-voltage and high-frequency environments, making them suitable for use as insulation materials and wire coatings in the electrical and electronics industries.
  • Flexibility is another important feature. Silicone remains soft even at low temperatures and can accommodate deformation without cracking, making it ideal for use in high-performance materials such as packing, sealing, and waterproofing. It also offers excellent weather and moisture resistance, maintaining its properties even after long-term exposure to external environments, making it an outstanding material for construction and disaster prevention.
  • Above all, silicone-based polymers are gaining attention for their eco-friendliness. They generate minimal harmful gases when burned and have excellent long-term durability, making them highly suitable for use as high-performance, eco-friendly building materials. Recently, the market has been expanding through the development of high-value-added application materials such as fireproof coatings, fire-resistant materials, and insulation. In particular, fire-resistant and insulating composite materials that combine silica fiber and aerogel are attracting attention as next-generation materials that overcome the limitations of existing materials.
