Thanks, I appreciate you shareing your experience and knowledge with me... It sounded a bit too good to be true,as is usually the case, it was...kip, since no one seems to know i researched a bit for you, first let me say i have tons of experience with pvc, so i looked up the sintra brand looking for similarities and differences. from the information i gained let me say this material would make a slingshot very easily............ but!
when heated say by the sun it becomes softer, bendable.
in the cold it becomes very brittle, you could snap a fork by dropping it.
sorry dooood
