Mold and Platen Insulators
Why Thermal Insulation:
With prices skyrocketing for Electricity, Natural Gas and Oil, one simple and economical way to achieve significant energy savings is to upgrade or install Thermal Insulation. When installed, Thermalate sheets will decrease heat transfer between the Mold and Press Platens. This results in more even temperatures throughout the process. Press insulation is a particularly demanding application for any material since it is subjected to high temperatures and molding pressures, as well as exposure to Oils and Hydraulic Fluids.
Our Thermalate grades are Compression Molded Glass Mat reinforced Thermoset Polyester laminates. Their physical properties include High Heat Resistance, high Compressive Set, low Thermal Conductivity, low Moisture Absorption, durability, and good machinability. These laminates provide for more precise temperature control as well as uniformity of temperature, reducing or eliminating “Cold Spots” in a mold.
Our Thermalate Advantages:
Thermalate composites offer a number of specific advantages over other insulation materials.
- Thermalate composites are asbestos-free
- Cost effective: increased efficiency allows for short payback period
- Low Thermal Conductivity/Energy efficient: Thermalate composites save energy and allow more precise temperature control
- High Heat Resistance: Thermalate is designed to operate at temperatures up to 550°F
- High compressive strength: Thermalate composities will not take a compressive strength “set”, causing mold alignment problems, when subjected to extremely high molding pressures
- Tough and durable: does not crack or break easily during mold setup or tear down. More durable than Mica or Asbestos materials
- Resist Oils and Fluids: Other more absorbent insulators, such as Concrete asbestos, can deteriorate or alter their thermal conductivity
- No Maintenance
What Differentiates Us:
Since we are a major fabricator, we are able to provide you not only with many varying sizes of Thermalate sheets but are able to fabricate to your drawings’ specifications. With our complete machine shop your Insulating Plates will be ready to bolt on when shipment is received with no further machining. This saves time, saves your equipment, blades and bits as well as keeps the dust out of your air.
Standard Stock Sheet Sizes:
As well as complete machining, we can also supply these standard size sheets 36 x 72 or 48 x 96.
Sheet size 48 x 60 is available upon request - minimums will apply. Special thicknesses from 1/4 to 2.00 are available.
Thermalate sheets up to ½ thick are sanded on both sides to a tolerance of +/-0 .002.
Thicknesses over ½ are sanded on both sides to a tolerance of +/- 0.005.

Unless otherwise indicated, all properties published are based on test performed on standard ASTM test samples and according to ASTM test methods. Values shown are for test samples made from production materials and they are believed to be conservative. No warranty is to be construed, however, in fabricated or molded form, parts may vary considerably from this standard test data. Where specific or unusual applications arise, test should be made on actual parts, and test procedures agreed upon between Synthane Taylor and the customer.
