Introduction to F4BTMS1000:
The F4BTMS series represents an advanced iteration of the F4BTM series, featuring significant breakthroughs in material formulation and manufacturing processes. This high-reliability material is enriched with a substantial amount of ceramics and reinforced with ultra-thin, ultra-fine glass fiber cloth, resulting in enhanced performance and a broader range of dielectric constants. It is particularly suitable for aerospace applications and can effectively replace comparable foreign products.
By incorporating a carefully balanced mix of ultra-thin glass fiber cloth and specially distributed nano-ceramics combined with polytetrafluoroethylene resin, the negative impacts of glass fiber on electromagnetic wave propagation are minimized. This innovation reduces dielectric loss, enhances dimensional stability, and decreases anisotropy in the X/Y/Z axes. Additionally, it improves electrical strength, thermal conductivity, and exhibits excellent low thermal expansion characteristics.
