Silicone pads for electrical equipment accessories

Silicone pad blocks, as a common accessory for electrical equipment, are widely used in fields such as electronics, industry, and home appliances, primarily serving key functions like heat conduction, insulation, vibration damping, and sealing. Their product characteristics and design fully meet the demands of modern electronic products for efficient heat dissipation and safe operation.

Basic Materials and Physical Properties

The silicone pad is made of silicone material, which is a highly active green product with excellent softness, elasticity, and chemical stability. At room temperature, it can undergo significant deformation even under minimal external force and quickly return to its original state, demonstrating outstanding compressibility and flexibility. Silicone is a completely amorphous polymer with a low glass transition temperature (Tg), typically exceeding several hundred thousand in molecular weight. It possesses thermoplastic and thermosetting characteristics, and its molding and curing process is significantly influenced by the type of vulcanizing agent and environmental temperature and humidity.

Additionally, the silicone pads are odorless, insoluble in water and any solvents, with some products meeting food-grade standards, making them environmentally friendly, safe, and free of any unpleasant odors.

2. Core Functions and Application Advantages

Thermal conductivity performance

Thermal conductive silicone pad blocks are essential thermal management materials in the electronics industry, commonly used for heat dissipation in high-power components. They effectively transfer heat generated by components such as CPUs, GPUs, LED aluminum substrates, and power modules to heat sinks or enclosures, improving overall thermal conversion efficiency. Compared to thermal conductive grease, although the thermal resistance is slightly higher, their sheet-like form facilitates easy cutting, clean operation, and minimal tolerances, making them suitable for automated assembly. They are particularly well-suited for space-constrained devices such as laptops, LED lighting, and automotive electronics.

Typical thermal conductivity ranges include:

Standard thermal conductive silicone pads: 1.0~2.0 W/m·K

Strong adhesion/strong toughness type: approximately 1.0 W/m·K

Electrical Insulation and Withstand Voltage Performance

Silicone spacer blocks exhibit excellent electrical insulation properties, typically meeting the UL-94V0 flame retardant grade requirements and are RoHS-compliant as certified by SGS. However, under high-voltage conditions (e.g., above 8kV), certain models may experience reduced insulation performance, necessitating selection based on actual operating conditions.

Buffering, shock absorption, and sealing functions

The white latex composite silicone gasket also features excellent shock-absorbing capabilities, capable of absorbing mechanical vibrations and reducing noise to protect precision instruments from impact damage. Its superior adhesion and flexibility make it suitable for both flat and curved surfaces, ensuring effective sealing in uneven or complex structures to prevent dust and moisture intrusion.
