JNS is a premier distributor and fabricator of Schott Borofloat® 33 glass.  JNS can provide full un-fabricated sheets, crates of Borofloat® glass or Borofloat® parts made to print.  SCHOTT Borofloat® 33 is a versatile borosilicate glass with excellent light transmission, thermal properties, and chemical resistance. Its unique properties make it desirable in many different applications, from high temperature lighting windows, view ports in extreme conditions, to the medical and semiconductor industry. Borofloat® wafers are an excellent substrate for MEMS (micro-electro-mechanical systems), as its coefficient of thermal expansion is very similar to silicon and allows for anodic bonding between the two. The low density of Borofloat® also makes it an excellent choice for lighter weight laminated glass systems such as bulletproof glass.
