Cglass

Cglass is a term used in the glass industry and materials science that does not denote a single standardized material. Instead, it is used as a designation in several contexts to describe different glass products or families that share a focus on chemical durability, thermal stability, or specialized performance.

In some contexts, C-glass denotes a class of chemical glass or corrosion-resistant glass designed for laboratory ware, reaction vessels, and piping where exposure to aggressive chemicals is expected. These variants typically utilize a silica-rich composition with reduced alkali content and additives that enhance chemical durability, reducing leaching and attack by acids and bases.

In other usages, C-glass refers to reinforced glass fibers marketed for composites. C-glass fibers are developed to provide a balance of strength, stiffness, and chemical resistance, and they are used to reinforce polymers in automotive, construction, and industrial components.

Because there is no universal standard for C-glass, specifications vary by manufacturer. Engineers and purchasers rely on data sheets that describe composition, density, thermal properties, chemical compatibility, and mechanical performance under relevant conditions.

Related glass families discussed in the same markets include E-glass and S-glass, as well as common soda-lime and borosilicate glasses.
