Sintra

Has anybody here used SINTRA and if so what do they think about it?
How does it cut, shaped, can it be carved, cut by hot-wire and so on and so forth.

Is "sintra" the same as "celtec"?

Nope, I guess Sintra is foamed polystyrene, and Celtec is foamed PVC.
I wouldn't breath any of the fumes if you use a hot wire to cut either.

I've had a look at some Celtec samples, my impression was that it was lighter for its thickness than a standard thin sheet of the same material.
This allowed a more rigid build without substantially increasing the weight.

The boat and bridge deck here are built of Celtec.

I would imagine that the "Sintra" handles similarly.

Sintra is a closed cell PVC, same as Celtec Umi.

I *think* that Forex (UK type) is also the same.

I must have read the "Sintrex" def.
