Graphite

The Protatherm® range of materials and products have been carefully developed to cater to the glass container industry's need for highly durable yet sympathetic contact materials. Not all carbon and graphite materials are made equal, and while Protahterm offers all the inherent advantages of graphite such as:

  + high mechanical strength
  + non-wetting
  + a natural lubricant
  + safe glass contact

We also believe our products offer a fine and superior balance between three key parameters for a succesful contact material.

  1. Oxidation resistance, excellent oxidation resistance which can be elevated even further using our anti-oxidation treatment
  2. Thermal conductivity, all of these material transfer heat at a low rate which greatly reduces the risks of cracks in the glass container due to extracting heat out of the glass.
  3. Hardness, the hardness too represents a balance between being hard and strong enough to hold fine detail in our take out inserts, and resist mechanical wear, while at the same time begin forgiving enough not to check the glass.

All of which adds up to a longer service life, reduced down time and greater pack rates.
