Technical tips |
|
Premium mechanical properties (Tg temperature 8~10 degree higher). |
Equal to "Hitachi chemical" HN-2200 |
Equal to "Hitachi chemical" HN-2200. But color sensitive applications, color constant after add accelerator (dielectric loss tangent lower than others). |
Exceptional color properties for MTHPA (good optical properties, mainly used in the same industries as the MHHPA). |
