Non-Silicone Lightweight Thermal Material
LiPOLY’s NL-putty series is Non-Silicone Lightweight Thermal Material, low-density gel filling material. Its low density and lightweight characteristics enhance product performance, reduce production costs, and minimize material usage and energy consumption. Commonly used in electronic products and automotive electronic devices, this series has a thermal conductivity of 4.0-10.0 W/m*K. The non-silicone property ensures no volatilization of low-molecular-weight siloxane, preventing electrical contact failures. It features high deformability, flexible gap adaptation, and tolerance compensation. The material overcomes overflow and drying issues, improves thermal conduction, and is suitable for automated dispensing production.
What is Low-molecular-weight siloxane?
The chemical formula indicates that the non-reactive cyclic polydimethylsiloxane Ho-[Si(CH3)2O]nH is volatile and volatilizes at any time. For example, when electronic products are in a closed space, the low volatile siloxane will cause obstacles to electrical contacts.
Non-Silicone Lightweight Thermal Material
For applications where silicone is not ideal, non-silicone TIMs offer a viable alternative. These materials provide many of the same benefits as silicone-based TIMs but are better suited for specific environments.
- No Outgassing Concerns: Non-silicone TIMs are often preferred in environments where contamination must be strictly controlled. Since they do not release VOCs, they are ideal for use in optical devices, medical equipment, or in environments with cleanroom requirements. Additionally, non-silicone materials are widely used in automotive applications, where silicone contamination can affect paint adhesion and other surface treatments.
- High Performance in Harsh Environments: Many non-silicone TIMs are designed to withstand harsher environmental conditions, such as exposure to oils, fuels, and other industrial chemicals. This makes them particularly well-suited for automotive and aerospace applications, where components are exposed to more aggressive environments.
- Thermal Conductivity and Stability: Like silicone TIMs, non-silicone alternatives can also offer high thermal conductivity and excellent stability over a range of temperatures. They are designed to provide reliable heat transfer while maintaining their structural integrity under various mechanical stresses. This makes them a good fit for applications such as LED lighting, industrial machinery, and telecommunications equipment.
- Variety of Materials: Non-silicone TIMs come in a wide variety of material compositions, including phase change materials, metal-based compounds, and synthetic polymers. Each of these offers specific advantages depending on the application. For instance, metal-based TIMs provide excellent thermal conductivity but may not be as flexible, while phase change materials can transition from solid to liquid to fill gaps more effectively under heat.
