Antimony Foil (Light Tight)

Formula: Sb

Form: Foil (Light Tight)

Material: Antimony

CAS Number: 7440-36-0

Commodity: Metals

Light Tight: Light Tight

Hazard Pictogram: GHS06, GHS09

Antimony Foil (Light Tight) is notable for blocking visible light while remaining flexible and thin. With thicknesses from 0.025mm to 0.5mm, we offer this foil in multiple sizes for applications like optical filters, radiation shielding and x-ray collimation. The light blocking properties of antimony combined with the flexibility of a thin foil make this an ideal material when visible light must be precisely controlled.
