According to the directory, silicone rubber typically operates from -60°C to 230°C, but this range should be confirmed for the specific grade and application.
Common standards include ISO 7619-1 for hardness, ISO 37 for tensile and elongation, ISO 812 for temperature range, and IEC 60243-1 for dielectric strength. Always verify compliance with the supplier.
Yes, it has high dielectric strength and volume resistivity, but the exact values depend on the formulation. Check the datasheet for the specific product.
Silicone rubber exhibits excellent UV and ozone resistance due to its inorganic backbone, making it suitable for outdoor applications. However, long-term exposure should be validated with the manufacturer.
