Glastherm Grade HT is a high compressive strength, heat-
resistant composite material. Finished to a close thickness
tolerance, it is ideal for installation between the mold and the press or within the mold itself. It is completely asbestos-free and rugged to withstand rough handling during installation. It is easily cut and machined with standard metal working
equipment. Diamond cutting tools are recommended for long
life. Compression molded for high impact strength, supplied
micro-finished top and bottom, parallel within ± .002.
