depending on the operating condition. Values are not guaranteed.
[ ! ] It cannot be used in Class 1 or Class 2 pressure containers,
or specified facilities for high-pressure gas.
[ ! ] (4) Due to the manufacturing process of FGLKR Nextreamer,
the base plate is produced using rollers,
so it is standard for the product to appear blurry when viewed through,
compared to other types of glass.

Product Specifications
Specifications / Overview
■ About heat-resistant glass (TEMPAX Float). It is a
borosilicate glass. Both faces are shaped into flat and uniform surface by floating method. Has optical quality with good light transmittance and no optical distortion.
■ Reinforced Glass
Float transparent glass with reinforce treatment applied. Configurable product can now be selected.
As the glass is heat-treated, processing such as cutting, chamfering, and hole machining is not possible after purchase.
■ About Heat-resistant Crystallized Glass (Nextrema 724-3)
high temperature range and has excellent thermal shock resistance.
In addition, can withstand high bending stress. Can be specified freely.

■ Characteristic Value
[ ! ] Values of thermal shock resistance indicate temperatures from which rapid drop does not lead to cracking.
[ ! ] Listed values are for reference, not guaranteed. Temperature characteristics and strength vary depending on the operating environment.
[ ! ] It cannot be used in Class 1 or Class 2 pressure containers, or specified facilities for high-pressure gas.
