The NFP series material is a high-performance, compressible, and silicone-free thermal pad specifically designed for silicone-sensitive applications. This material is ideal for environments where silicone presence is a concern, as it features low volatility, no silicone oil penetration, and prevents contamination of PCB circuits.
The NFP series is characterized by its soft texture, high compressibility, and excellent surface wetting properties, which lead to minimal thermal resistance between heat-generating components and heat sinks or housings. These qualities make it an excellent choice for applications where traditional thermal pads may be unsuitable due to their silicone content.
The material is naturally tacky on both sides, eliminating the need for additional adhesive coatings. Its inherent tackiness ensures the pad stays securely in place during assembly and operation, making the material easy to handle and facilitating the processing and assembly of heat-sensitive components.
