AOK thermal gap fillers are well-regarded for their high-performance thermal management solutions, particularly in automotive, electronics, and industrial applications. AOK thermal gap fillers are versatile, reliable, and highly suitable for automotive electronics applications, offering a range of thermal conductivities and physical properties to suit different thermal management needs.

1. Thermal Conductivity Range

Variety of Conductivities: AOK offers a broad range of thermal gap fillers, with thermal conductivities ranging from 1.0 ~ 15 W/m·K. This allows engineers to select materials based on the specific heat dissipation needs of their application. Low Conductivity (1 ~ 5 W/m·K): Suitable for moderate heat dissipation in standard applications. High Conductivity (5+ W/m·K): Used in high-performance or high-power applications where significant heat transfer is required.

2. Softness and Conformability

Excellent Compressibility: AOK thermal gap fillers are designed to be soft and easily compressible, which allows them to conform to irregular surfaces and fill even small gaps between components and heat sinks. Reduced Pressure on Components: Their softness ensures that the gap filler does not apply undue pressure on delicate electronics, helping to protect sensitive components while maintaining good thermal contact.

3. Wide Operating Temperature Range

AOK thermal pads are designed to work effectively across a wide temperature range, often from -40°C ~ +200°C or more. This makes them suitable for automotive electronics, where the components are exposed to extreme temperatures in both hot engine compartments and cold climates.

4. Electrical Insulation Properties

High Dielectric Strength: Many AOK gap fillers are also electrically insulating, which is critical in applications where thermal management needs to be combined with electrical isolation. This quality ensures that heat can be dissipated without causing short circuits or electrical interference.

5. Durability and Reliability

Vibration and Shock Resistance: AOK gap fillers are built to withstand the mechanical stresses of automotive environments, including vibrations, shocks, and movement. This ensures that the thermal pad remains in place and effective over the lifetime of the device. Aging Resistance: These gap fillers are engineered to be long-lasting, maintaining their properties over time without degradation due to heat, cold, or mechanical stress.

6. Environmental Certifications

RoHS Compliance: AOK products comply with Restriction of Hazardous Substances (RoHS) directives, ensuring that they meet environmental safety standards, which is crucial in automotive and consumer electronics. UL and ISO Ratings: Some gap fillers have certifications like UL 94 V-0, indicating flame retardancy, and may also meet ISO 9001 standards for quality management.

7. Various Thicknesses and Form Factors

AOK offers thermal gap fillers in a variety of thicknesses, generally ranging from 0.2 ~ 12mm or more, depending on the application’s requirements. This ensures that different gap sizes and configurations can be adequately filled. Custom Shapes: Some AOK products can be custom-cut or shaped to fit the precise dimensions of complex electronics, offering flexibility in design.

8. Reinforced Options

AOK also offers reinforced thermal pads with materials like fiberglass, which provide additional mechanical strength while maintaining thermal conductivity. These are particularly useful in applications where the pad may need extra durability.
