Product physical property:

Borosilicate glass has a very good homogeneity and very high transparency in the UV/visible/near IR range. The glass has low thermal expansion and high thermal resistance that make it particularly suitable for areas of application where high temperatures and thermal gradients are involved.

Thermal Properties

Borosilicate glass has one of the lowest coefficients of thermal expansion for conventional glass materials, this provides with good thermal shock resistance. Combined with a maximum long term use temperature of 450°C, which makes borosilicate glass a good choice for applications requiring good thermal stability.
