X-RAY PROTECTIVE glass because of its excellent radiation shielding capability and
high light transmittance, radiation shielding lead glass LX-57B  has many medical and
laboratory applications, as well as being widely used in nuclear power industries.
Since the LX-57B glass is melted in a tank furnace and rolled continuously, We are is
able to supply large-size and high-quality LX-57B glass readily upon demand.

Approved Product

With a lead oxide content of 55%, LX-57B glass has excellent radioactive shielding
capabilities. For example, 9mm thick LX-57B has the same X-ray shielding
capabilities (lead equivalent: 2.0mm Pb) as 2mm thick lead plating. LX-57B is a
technically approved product

Excellent Transparency

LX-57B has a grade of optical glass quality. Because both surfaces are optically
polished it allows very high light transmittance. This transmittance is almost the
same as that for a normal windows glass. Because of its excellent transmittance,
LX-57B can be used with great advantage in observation and operation windows of
radiation equipment.

Glass Characteristics

LX-57B would not be combustible even in the unlikely event of a fire because it is an
inorganic glass. It also has excellent chemical resistant properties. LX-57B is easy to
process. It can be easily formed into a disk plate, or drilled for glove box.
Large Sizes Increase the Field of Vision

The largest LX-57B product is 1,200 x 2,600mm. Using large-size LX-57B for
observation and operation windows in X-ray TV rooms, CT scanning rooms and
angiography rooms provides a wider field of vision and improves operations.
Glass over 14.0mm in thickness available on request.
