Platen insulation is available in a variety of grades

All grades of platen insulation sheets offer both high physical strength and low thermal conductivity.

Grade HT Sheet

Our thermal platen insulation Grade HT is ideal for plastic and zinc die cast molds with operating temperatures up to 550o F. It effectively reduces heat loss, providing faster start-ups and greater operating efficiency.

Grade HT is durable enough to provide a long service life and rugged enough to withstand rough handling during mold changes.


  • Reduces heat loss
  • Helps control temperature
  • Enables faster mold start-up
