Borosilicate glass balls are made from the special glass of the first hydrolytic class, which is wellknown for its stability and
pressure resistance,good workability and high thermal shock resistance due to its low rate of thermal expansion.
Characteristic:
Borosilicate glass balls are resistant to corrosion and remain absolutely neutral, even to aggressive chemicals in nearly all fields of chemistry. It is extremely resistant to water, acids, organic substances and halogens and it also has a high alkali resistance.
In all:
(1).Borosilicate glass balls can withstand high thermal shock;
(2).extend exposure to temperatures of up to 600'F(290'C)
(3).It have very high electrical resistivity and dielectric strength;
(4).It have high chemical stability, withstands high applied torque loads..
