Three grades of Glastherm insulating sheet are currently available. All three offer a combination of high physical strength and low thermal conductivity.
Glastherm Grade S Sheet
A general purpose insulating sheet with an economical combination of thermal and physical properties. Recommended for processes where the continuous operating temperature does not exceed 425°F. Grade S is particularly suited to the rubber molding industry.
Glastherm Grade HT Sheet
A thermal insulating sheet with superior strength and heat resistance for applications with continuous use temperatures up to 550°F. Designed for plastics and zinc die cast mold requirements.
Glastherm Grade CH Sheet
The best press insulating sheet available today. Grade CH has a unique combination of thermal endurance, high hot compressive strength and low thermal conductivity. Designed for applications where polymer-based insulators have not performed in the past. Grade CH performs well at temperatures in the area of 395°F.
