Lead
Main products（Lead Unit）
Mobility Energy Raw materials / Resources / Recycling
raw materials
Lead is primarily used as electrodes for lead storage batteries. We manufacture JIS-compliant lead with a purity of 99.99% or higher.
Mitsui Perlite
Main products（Perlite Business）
Energy Life / Environment Parts / Building materials / Structural materials
raw materials Parts / materials
Mitsui Perlite is formed by crushing pearlstone, a natural volcanic glass, or pitchstone. This is then rapidly heated and allowed to expand, resulting in an airtight amorphous structure that is very light and has a white sand-like appearance.
