Introduction
Kynar and silicone are two popular materials used in various industries, including construction, aerospace, and automotive. These materials have unique characteristics that make them suitable for specific applications. In this article, we will compare and contrast Kynar and silicone and discuss their respective uses.
What is Kynar?
Kynar, also known as polyvinylidene fluoride (PVDF), is a high-performance thermoplastic material. It is resistant to corrosion, abrasion, and UV radiation, making it ideal for outdoor applications. Kynar has excellent chemical resistance and can withstand high temperatures, up to 150°C. Its low coefficient of friction and electrical insulation properties make it suitable for various industrial applications, including chemical processing, oil and gas, and medical.
Properties of Kynar
- High chemical resistance
- UV resistant
- Abrasion resistant
- Low coefficient of friction
- Excellent electrical insulation
- Temperature resistance up to 150°C
What is Silicone?
Silicone is a synthetic polymer made of silicon, oxygen, carbon, and hydrogen. It is a flexible, non-reactive material that can withstand high temperatures, up to 300°C. Silicone is used in various industries, including construction, automotive, and medical. Its flexibility and durability make it an ideal material for applications that require sealing, insulating, or lubricating.
