High-performance insulation type (viscose based carbon fiber felt)
High-performance insulation type (viscose based carbon fiber felt)
product Description
Imported high-quality viscose fiber short filaments are used to optimize the needle-punched structure, and then high-quality graphite felt is made through impregnation catalysis, pre-oxidation, carbonization and graphitization processes. Its appearance is regular, with uniform thickness and width; the surface color is uniform and black gray; it is soft to the touch and has low basic ash content; the fiber diameter is thinner, and the heat insulation performance is better.
