DuPont Zytel. Strengths and Uses 1

[MechEng13]

Group,

I have a potential customer that would like to have an extrusion die made from Dupont's Zytel Polymide. I am wondering what are it's advantages/disadvantages. All I know to this point is its a glass reinforced Nylon, but on Matweb there are 140 varieties. Any Help you can offer will be greatly appreciated.

A polymer extrusion die will have low wear resistance, low stiffness, low heat resistance, and creep due to sustained loading. What material would be extruded? There may be problems if the material isn't soft (like Play-Doh).

I believe it's going to be lawn care type stuff...not sure of the actual extrudate yet. The customer is asking for designs in 440C SS, Delrin, and Zytel...The Zytel has a melt point in the low 600 F Range.

No offense MechEng13, but melting temperature is not important - see the properties I listed above. It may be that a polymer will have sufficient resistance to stresses and temperatures of this application, but caution is warranted.

No offense taken. I am just trying to find out as much as I can to discuss with the customer. Maybe the conversation will light the bulb. At this point I don't understand the concept behind having a polymer extrusion die. My knowledge of extrusion says the the pressures building up behind the die are quite high and would cause problems with a Nylon die. There must be a reason they want it, or they wouldn't have asked for it. Just trying to find the reasoning behind it.

We'll see what the customer says.

Thanks for the help so far.
