5280 High-Performance Precipitated Silicone Rubber

Product Overview
The 5280 is a high-quality, translucent, general-purpose precipitated silicone rubber designed for industrial applications that require a perfect balance of durability and cost-efficiency. Engineered for excellent processing performance, it provides high mechanical strength and superior electrical insulation when paired with the T-1A vulcanizing agent.

Key Features & Benefits
Exceptional Physical Durability: With a tensile strength of 8.4 MPa and a tear strength of 17 KN/m, this material ensures that finished products are resistant to mechanical stress and tearing.

Superior Thermal Stability: The 5280 grade is designed to withstand extreme environments. After 10 days of continuous exposure to 200°C, it maintains stable hardness and physical integrity, making it ideal for high-heat applications.

Excellent Dielectric Properties: Boasting a dielectric strength of 26 MV/m and high volume resistivity, it serves as a reliable insulating material for sensitive electronic and electrical components.

Balanced Hardness: At a Shore A hardness of 70, it offers the ideal structural support and resilience needed for precision molded parts.


Typical Applications
Electronics & Electrical: High-insulation gaskets, seals, keypad components, and protective sleeves for electrical assemblies.

Industrial Sealing: Heat-resistant O-rings, gaskets, and seals designed for long-term use in demanding industrial machinery.

Automotive Components: Heat-shielding parts, vibration dampeners, and internal seals that require consistent performance under the hood.

General Silicone Goods: A versatile choice for various molded silicone products where transparency and mechanical reliability are essential.
