Ensure Thermal Stability Using Silicone Rubber Parts
Introduction
For applications requiring extreme heat resistance and flexibility, silicone rubber is the superior material. Unlike organic rubbers, silicone rubber maintains its mechanical properties across a wide temperature range. This article explains why silicone rubber is essential for high-performance manufacturing.
1. What Is Silicone Rubber?
Silicone rubber is an inorganic polymer comprised of silicone, carbon, hydrogen, and oxygen. Its unique chemical structure allows it to remain flexible at low temperatures and stable at high temperatures.
2. Why Use It? (Benefits)
Thermal Stability: It functions reliably from -60°C to over 200°C.
Biocompatibility: Specific grades are non-toxic and suitable for medical or food contact.
Electrical Insulation: Excellent insulating properties make it ideal for electronics.
