GASKET PROPERTIES

IF GASKET IS EPDM FOOD GRADE THEN WHAT IS THE m & y VALUES of gasket?

ARE TOSE SIMILER TO VEGITABLE FIBRE GASKET?

You are out of your mind!!!!!!!!!

get a life....................

Sorry, impossible to determine what do you mean with that. Try to post a consistent question again, please.

Do you know a word Gasket

If yes try to get some knowldge about its properties from ASME SECTION VIII DIV 1

While I have never worked with either foodgrade EPDM nor vegetable fibre gasketing, I will offer this:

Foodgrade EPDM will have very similar gasketing characteristics of regular EPDM (synthetic rubber);

• Below 75A shore durometer: m = 0.50; y = 0
• Above 75A shore durometer: m = 1.00; y = 200 psi

Vegetable fibre is different from EPDM and has the following factors:

• m = 1.75; y = 1100 psi

(Values from ASME Section VIII Div 1)

thanks

In ASME Section VIII Div 1, m & y values for EPDM Food Grade are not given.

From where you get these values for EPDM?

Is there any reference book?

I got those "regular" EPDM values from ASME VIII-1 as well, I assume that food grade (FDA) will have very similar (if not exact) characteristics.

You can always ask your gasket supplier.

Please turn off Caps Lock. Many readers consider the use of all-capitals rather rude.

I am currently experiencing a similar problem, when attempting to determine the m and y values for a "James Walker TC 500 14 x 14mm Nitrile ring bonded in PTFE envelope" gasket. I have consulted ASME VIII Div.1 and am unsure as to which values should be used. Any help in this regard would greatly be appreciated.
