Where can I get polydimethylsiloxane

can someone help me please

Thank you

I'm not a chemist but unless I misread your question, aren't you just asking about silicone oil? Look at the results from http://www.amazon.com/s/field-keywords= ... ylsiloxane and see if that gets you close. If not, maybe explaining more in detail of what you're looking for will help the chemists here help you.
