Material Notes:
Haysite’s family of mold and platen insulation products are specially engineered fiberglass reinforced thermoset polyester composites which offer superior energy efficiency, temperature control, and durability for high temperature mold and platen thermal applications. Haysite Thermalate® composites offer a number of specific advantages over other insulation materials:Asbestos FreeCost Effective: Increased efficiency allows for short paybackLow Thermal Conductivity/Energy Efficient: Saves and allows more precise temperature controlHigh Heat Resistance: Designed to operate at temperatures up to 550ºFHigh Compressive Strength: Will not take a compressive “set”, causing mold alignment problems, when subject to extremely high molding pressuresTough and Durable: Does not crack or break easily during mold setup or tear down. More durable than mica or asbestos materialsResists Oils and Fluids: Other more absorbent insulators, such as concrete asbestos, can deteriorate or alter their thermal conductivityNo MaintenanceInformation provided by Red Seal Electric Company.
