Why Traditional Elastomers Fail and How Silicone Rubber Composites Replace Them
Problem
A global power equipment manufacturer faced ongoing issues with insulation degradation, weather-related aging, and shortened service life in outdoor electrical components. Conventional elastomer materials struggled under prolonged exposure to UV radiation, pollution, moisture, and extreme temperature variations, leading to increased maintenance requirements, performance instability, and higher lifecycle costs.
Solution
The manufacturer replaced traditional elastomers with advanced Silicone Rubber Composites. These composites are engineered by combining silicone elastomers with high-performance reinforcing fillers such as silica, ATH (aluminum trihydroxide), glass fiber, or specialty ceramics. The resulting material system delivers exceptional thermal stability, electrical insulation, hydrophobicity, and resistance to aging, while also providing superior tracking and erosion resistance. Long-term hydrophobic recovery ensures sustained surface performance even in heavily polluted or wet environments.
Result
After adopting silicone rubber composites, the manufacturer achieved significant improvements in insulation reliability, weather resistance, and overall service life of outdoor electrical components. Compared with traditional rubber or polymer insulators, the new material solution delivered stable long-term performance, reduced failure rates, and lower maintenance demands. Its lightweight structure and design flexibility further enabled easier installation and improved system efficiency.
Impact
This case demonstrates how Silicone Rubber Composites solve critical durability and reliability challenges in harsh outdoor and industrial environments. By enabling long-lasting insulation performance under extreme conditions, these composites have become a key material technology across power transmission, automotive, and industrial applications. QY Research has recently published a comprehensive market study on Silicone Rubber Composites, with key findings summarized below.

Case Study for Bidding
Time: April 2024
Supplier: Wacker Chemie AG
Buyer: High-Voltage Power Equipment Manufacturer (Europe)
Product: ATH-Filled Silicone Rubber Composite (Outdoor Insulation Grade)
Quantity: 26,000 tons
Contract Value: USD 152 million
Delivery Timeline: March 2025
Detailed Application Scenario
The power equipment manufacturer adopted Wacker's ATH-filled silicone rubber composite for outdoor insulators and cable accessories used in high-voltage transmission networks. The composite's excellent hydrophobicity and erosion resistance prevented surface leakage currents and flashover even under heavy pollution and high humidity. Its inherent UV and ozone resistance ensured stable mechanical and electrical performance over long service lifetimes.
The lightweight composite design reduced installation labor and structural load compared with porcelain alternatives. Long-term field tests demonstrated minimal surface degradation and strong hydrophobic recovery after contamination, significantly lowering maintenance requirements. The project confirmed how silicone rubber composites deliver enhanced safety, durability, and lifecycle cost advantages in modern electrical and industrial infrastructure.
