PTFE Graphite Packing – Type: CH PT2 -200°C+280°C 120 bar 25 m/s 0-14

Carsten Holms CH PT2 is 100% GORE® fibre packing. This remarkable yarn is constructed from PTFE and Graphite intimately blended and locked and then treated with a high temperature, break-in lubricant. CH PT2 is an outstanding packing for use in aggressive or arduous duties including the most difficult chemical environments. It is essentially chemically inert over the entire pH range. The unique combination of locked graphite and PTFE creates a yarn with very high thermal conductivity, that does not harden, shrink, swell nor dry out and that is exceptionally smooth running with negligible shaft wear. In practically all cases, greatly extended service life can be expected.
In order to obtain maximum benefit from this fibre, CH PT2 is square interbraided via a CROSS-LOK process. The construction of CH PT2 increases the durability of the packing and reduces the gland pressure required to perform a seal. Periods between gland maintenance and packing replacements are thus even further extended and CH PT2 CROSS-LOK braiding helps overcome extrusion problems, which can be the one negative of this fibre, particularly in lower quality braids.

PRODUCT ADVANTAGES
• Easy installation and removal
• Excellent resistance against chemicals
• Inert over the entire pH range     
• High thermal conductivity
• Extended service life

APPLICATION
For use wherever the value of the best quality and material packing can be realised. Since the actual purchase cost of a packing is typically only 3% of the true utilisation cost, Carsten Holm A/S recommend these PTFE Graphite packings for all possible applications. They will increase service life whilst minimising wear and gland adjustments, against nearly all media in static, rotary and reciprocating uses.
