New Fashion Design for PTFE Envelope EPDM Gasket to Istanbul Manufacturer

PTFE envelope EPDM gasket utilizing PTFE jacket have become popular for use in severely corrosive services because of its low min. Seating stress, excellent creep resistance, high deformability and choice of a variety of filler materials to assure optimum performance on any specific application.

Product Feature:

l Virtually 100% chemically resistance

l Temperature resistance: -200~+260℃

l Pressure resistance: 4Mpa

Application

PTFE envelope gaskets are widely used in food and process industrial where contamination of the medium can not be permitted. Suitable for medium strong alkalis, cryogenic fluids, oxygen, chlorine gas 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?
