GBT ViaTHERM NFP series material is high-performance, compressible, and silicone-free. Material is suitable for silicone-sensitive applications, featuring low volatile, no silicone oil penetration, and no contamination to PCB circuits.
NFP series materials has a soft texture, high compressibility, and excellent surface wetting characteristics, resulting in low thermal resistance between heat source components and heat sink or housing. This makes it ideal for applications where conventional thermal pads are used, but are sensitive to silicone. The material is self-tacky on both sides, without the need for additional adhesive coatings. The inherent tackiness of the material makes it easy to keep the pad in the desired position during assembly and usage, facilitating processing and assembly.
