Glass Handling Graphite Grades

Heat-resistant, durable, hot glass-handling graphite materials that perform under the most rigorous conditions and reduce cost of ownership.

Our portfolio of GLASSMATE® graphite materials are specifically designed for use in hot glass-contact applications. These materials have the heat resistance, strength, durability, and non-absorption characteristics that enable our precision-machined parts to perform under the most rigorous conditions without damage. Creation of tightly controlled isotropic grains produce finished parts with predictable behavior, enabling reliable, repeatable production runs. Our hot glass-handling materials offer excellent performance and reduce mechanical damage, increasing pack rates.

Our graphite grades are available as billets, semi-finished rods, blocks, plates, and fully machined parts.
