Thank You unclefastguy.

Will check out PTFE & the link U have given.

When you want to replace PP with PTFE you will run into a little problem: PTFE is not processable as PP, you can't use injection moulding.

Look into PTFA or PFA, which can be injection moulded, and are still superior than PP in temperature resistance.

UHDPE would be an option, depending whatcha wanna dooo.

(nice french, huh?!)

Sorry folks, I guess I was not very clear about the purpose of my question.

It is for an INJECTION MOLDED JIG used for holding PolyCarbonate Keys, which are to be pasted on to a Silicone Rubber Keypad.

Any accidental spillage of Cyanoacrylate from the dispenser should not result in the keys getting stuck to the jig.

PFA or UHDPE would work out I think.

Alternatively I can try to machine the jig out of a Teflon block ??

Thank you Gwen & Faustfix.

Hi Suresh

As you ask for dimensional stability, PTFE may not be strong enaugh, plus, it is heavy and expensive too.

However, in a recent project we tried various polymers, which we in fact needed to stick to cyanoacrylate. One which did not adhere very well, was ERTACETAL, aka POM-C, which is available both as a semi finished product or as injection mould granulate.

Dimensionally very stable, unlike PTFE which is somewhat difficult to clamp in a chuck or vice, it is easy to machine, and with some very useful friction properties in connection with metals. This material even has a good shape memory and will not flow out of shape when pressure is applied for a prolonged periond of time.

good luck

Dear Hangwaiter,

I believe POM-C is Acetal Co-polymer? If it resists adhering to Cyanoacrylate it should do the job. All other properties are what I require.

Lotsa thanx.
