What is a Silicone Free Thermal Pad
Like silicon-based materials, GALLOP INNOTEK’s silicone-free thermal pad is a thin-sheet channel that achieves heat conduction by adhering to the surface of materials used in daily applications.
Silicone-free thermal pad, also called Non-Silicone thermal pad. Certain specialized industries, such as those involving medical equipment and optical instruments, have specific requirements that preclude the use of silicone-containing materials, thereby driving the development of silicone-free alternatives.
Unlike traditional silicone-based thermal pads, GALLOP INNOTEK silicone-free thermal pads utilize a highly conductive bonding material made from special resins and other materials. These pads address the issues of oil seepage and volatility associated with traditional silicone-based materials, and some even incorporate metal oxides as auxiliary additives.
What are the Key Features of the Silicone-free Thermal Pad?
Silicone-free
The use of special resins and polymer materials prevents silicone oil from volatilizing and leaching, which could contaminate sensitive components. In electrical components, this characteristic ensures longer-lasting, reliable stability of your devices. Even after high temperatures or chemical treatments, the silicone-free nature prevents the release of gaseous silicone oil. While silicone-based materials are popular, they also present numerous challenges. The advent of silicone-free thermal pads has effectively addressed the thorny issue of corrosion in electronic component thermal conductivity, making GALLOP INNOTEK silicone-free thermal pads an ideal choice for heat transfer pathways in precision electronic components.
Excellent Thermal and Mechanical Properties
GALLOP INNOTEK silicone-free thermal pads offer you excellent thermal conductivity. For example, the GTP080-NS has a thermal conductivity of 8.0W/m.K, making it suitable for a wide range of precision components. Their soft and compressible properties allow them to accommodate the tight tolerances of precision component surfaces, making them an ideal choice for precision components in specialized industries.
Highly reliable and environmentally friendly
GALLOP INNOTEK silicone-free thermal pads are suitable for applications sensitive to silicon. They exhibit no performance degradation over long-term use and are resistant to aging and wear, significantly outperforming traditional silicone-based thermal pads prone to silicon leaching. Furthermore, since GALLOP INNOTEK silicone-free thermal pads release no volatilization of silicon compounds during use, they significantly reduce environmental pollution during disposal.
Silicone V.S. Silicone Free Thermal Pad
GALLOP INNOTEK thermal pads are crucial for your thermal management in electronic devices. Both silicone-based and silicone-free materials offer distinct characteristics and advantages.
Common silicone-based thermal interface materials are primarily composed of silicone polymers, such as silicone oil, mixed with other fillers. Due to their excellent vibration and chemical resistance, as well as ease of application and removal, they are widely used in various electronic products, particularly those requiring frequent maintenance and replacement. While they offer you excellent heat dissipation, they suffer from significant drawbacks: outgassing and precipitation caused by high temperatures can lead to contamination, corrosion, and wear on smooth surfaces. Furthermore, their high cost has led to the emergence of alternatives.
GALLOP INNOTEK silicone-free thermal interface materials are fundamentally different from silicone-based materials. They are formulated without silicone and rely on non-silicone polymers such as acrylic, metal, or ceramic to achieve their desired performance. They are particularly suitable for applications requiring high electrical insulation. If environmental risks are a concern when selecting a material, GALLOP INNOTEK silicone-free thermal pads may better suit your application requirements compared to silicone-based thermal pads.
Both silicon-based and silicon-free materials have their place in modern electronics thermal management. Silicon-based materials are suitable for high-temperature, rugged environments, while silicon-free materials are more suitable for applications requiring superior electrical insulation and a certain degree of protection against contamination risks.
How does a Silicone Free Thermal Pad Work?
Filling and Lamination
As you know, silicone-free materials use a polymer matrix combined with oxide-based thermally conductive fillers to create a highly conductive thermal path. Once manufactured, the soft, compressible properties of GALLOP INNOTEK silicone-free thermal pads allow for a tight fit between heating components and heat sinks. Their excellent electrical insulation properties allow for precise bonding, even without tools, resulting in superior mechanical isolation.
Heat Transfer Mechanism
Unlike previously described thermal pads, for example, the graphene material’s longitudinal network-like heat conduction and the silicon-based material’s unique ceramic particle bonding are notable differences. GALLOP INNOTEK silicone-free thermal pads mainly transfer heat through your thermal composite structure – physical contact of thermal conductive fillers, the support and fixation of the polymer matrix to prevent sliding, and the ability to maintain good thermal conductivity for you in high temperature environments, which effectively avoids contamination and even circuit failure caused by the migration of silicone oil and silicone resin.
Electrical Insulation
GALLOP INNOTEK silicone-free thermal pads also offer you excellent electrical insulation, effectively preventing the risk of short circuits during use. Furthermore, the GALLOP INNOTEK GTP015NS REV01 silicone-free thermal pad, for example, boasts an astonishing thermal conductivity range of -60°C to 125°C. This means that even in environments with temperatures exceeding boiling water, GALLOP INNOTEK silicone-free thermal pads offer excellent high-temperature and high-pressure resistance, as well as excellent mechanical stability, ensuring long-term, reliable operation under harsh conditions.
