In 1985, in recognition of the arrival of the electronics age, Hayashi Pure Chemical (HPC) was quick to incorporate electronic materials into its product line.
To bolster its R&D framework, HPC established its Techno Center in 2005 as a development hub.
HPC evolved into a quality-centered enterprise that supports the manufacture of LCD panels and semiconductors.
Looking to fill emerging market needs, HPC grew through technological innovation.
