The FTIR concludes the presence of an Oil similar to Castor Oil or Tall Oil.

There is a plastic casing an a wire wrapped comming inside of the casing.

Any idea or where does it can came, Wire wrap, plastic case....  

RE: HELP plastic cracking/breaking HELP

What kind of plastic?

"There is a plastic casing an a wire wrapped comming inside of the casing. "

Maybe a picture would help, as that description just doesn't work for me.

"Any idea or where does it can came, Wire wrap, plastic case....  "

Ok, please translate that into English? :)  Again, a picture would help.

And you might get more help on plastics...in a plastics material forum?

RE: HELP plastic cracking/breaking HELP

It could be a cheap-arse mold release agent.   I've seen companies use FISH OIL in molds to save money, often with hysterical results.    Soap, vegetable oil, CRISCO...

Another possibility, post production.   It could be a lube used on a secondary assembly machine or process.

Failing that,  maybe one of your operators has greasy hands.
