Wholesale price stable quality Aramid Fiber Braided Packing with PTFE Impregnated Supply to South Korea

Aramid fiber PTFE packing is braided from high quality Dupont aramid fiber with PTFE impregnated and lubricant additive. This packing can bear higher pressure applications than other types of braided packing. Due to its steel like strength, this yearn can used separately or as back up rings with other types of packing. This packing has been developed to replace asbestos packing for pump systems. It covers all the service ranges which asbestos packing provides and even much better.

Technical Data Sheet

Application Area

It affords longer service life under severe conditions which conventional asbestos packing can bot provide satisfaction, such as mine, tin ore, paper pulp, feed water pump of power stations, etc.

I built a physical deposition chamber, for now it’s just evaporative deposition but I plan on adding a few other variants. The thin films created can be used in many ways.
The chamber still has a ton of space leftover and I have some more equipment coming so hopefully I can do more interesting things.
Sorry there’s no footage of lathing the feedthroughs, they worked nice with a cut o-ring and some heat shrink. Make sure you cut a slot down the holding screw threads to vent behind em. The 2 copper feedthroughs allow (with a center tap) 2 tungsten boats with different metals so I can avoid opening the chamber in a multi layer coating.
The pump down takes about 45 min. to get to 10e-5. I can use a small steel hemisphere with a kf40 hose on the top for use with a secondary high vacuum chamber. The shutter was aluminum flashing with some steel stuck on one side so a neodymium magnet on the outside of the bell jar could move it around without a feedthrough.
This build was really fun

I got everything from mcmaster, K.j lesker, ebay and what I already had

This did cost a bit to make:
diffusion pump- $160
mechanical pump-$140
plate- $270 (ouch!)
valves- $90
gauges- $200
misc vacuum stuff -$120
bell jar – $140 (stupid)
other stuff – maybe $100?

he has done some neat stuff with his setup and a bunch of other things
