BOROFLOAT® 33 - Borosilicate glass

The world´s first floated borosilicate glass – Made in Germany with IQ 

More than 20 years ago, SCHOTT set up the first mi­crofloat pro­duc­tion line for the man­u­fac­tur­ing of what would soon become one of the most in­flu­en­tial spe­cialty glass ma­te­ri­als. The result was BOROFLOAT® 33 – the world’s first floated borosil­i­cate glass. With high-qual­ity German en­gi­neer­ing at its core, BO­ROFLOAT® 33 quickly became an out­stand­ing example of what happens when advanced knowl­edge, in­no­v­a­tive tech­nol­ogy and pro­fes­sional cu­rios­ity are com­bined.  The long-stand­ing in­ter­na­tional success of BO­ROFLOAT® is what drives us to improve. We work closely with our cus­tomers to offer high-qual­ity so­lu­tions that help to unlock new markets and meet the most tech­no­log­i­cally de­mand­ing ma­te­r­ial re­quire­ments. With BOROFLOAT® the key to it all!

Outstanding thermal resistance

Outstanding thermal resistance
BOROFLOAT® is the glass that specialists rely on when working with high fluctuations in temperature. Temperatures as high as 450 degrees Celsius pose no problem whatsoever for our specialty float glass. Not even in the case of unexpected cooling.

Exceptionally high transparency

Exceptionally high transparency
BO­ROFLOAT®´s ex­cep­tion­ally high trans­parency makes it a key ma­te­r­ial of choice for optical applica­tions in re­search and in­dus­try. Its unique light trans­mis­sion over a wide spec­trum offers cus­tomers a vast wealth of new pos­si­bil­i­ties.

High chemical durability

High chemical durability
High chem­i­cal sta­bil­ity is another key feature that dif­fer­en­ti­ates BO­ROFLOAT® glass from other ma­te­ri­als. Neither acids, alkalis nor other types of fluid can impair the per­for­mance of our special float glass, making it an ideal en­abling ma­te­r­ial for the chem­i­cal in­dus­try, as well as for use in medical and an­a­lytic tech­nol­ogy.

Excellent mechanical strength

Excellent mechanical strength
Spe­cialty glass must be able to with­stand a number of chal­leng­ing factors. Par­tic­u­larly when used in some of the most tech­ni­cally chal­leng­ing fields. A study con­ducted by the renowned Fraun­hofer In­sti­tute has proven that BO­ROFLOAT® has higher me­chan­i­cal strength than other spe­cialty glass types – and it is even lighter! *
