Röchling GLASTHERM HT250 Insulation Sheet
Categories:	Polymer; Thermoset; Composite SMC; Filled/Reinforced Thermoset; Polyester, TS
Material Notes:	Glastherm Grade HT250 is a high compressive strength, heat-resistant composite material. It is ideal for insulation between the fold and the press or within the mold itself. Grade HT250 is asbestos-free and rugged to withstand rough handling during installation. Grade HT250 is employed to save energy during pressing and is mainly used in hydraulic, wood and tire presses.
