We offer "low dielectric constant black dispersion liquid" as an item to easily achieve low dielectric constant.
It is considered that "low dielectric constant" is an effective factor in achieving "low latency" in next-generation communication systems. Features: - The black nanoparticles are uniformly dispersed, resulting in good coloration and excellent long-term stability. - They have a significant advantage in terms of low dielectric constant compared to conventional black nanoparticles (carbon black) (they can maintain a low dielectric constant). - We are designing for dispersion (and compatibility design) using NMP/DMAc as the main solvent, with the intention of imparting color (black) to low dielectric materials such as polyimide (PI) and liquid crystal polymer (LCP), as well as for circuit concealment. - Please consult us for customization options such as solvent changes to cyclohexanone (anon)/MEK/toluene for low dielectric materials like epoxy/bismaleimide/cycloolefin polymer (COP)/polyphenylene ether (PPE), as well as improvements in compatibility.
