Blue Cavern

Hiya guys !:hiya:

As I mentioned in another thread http://www.forum.bluecavern.com/viewtop ... &start=100, I came across a very odd Santa. Somehow the colour of the overcoat has altered on some place from red to a flo yellow, furthermore the sack has turned into grey and the trumbone looks odd as well. I highly assume, that this could result from acid though. I guess Joaquin could be an expert on that topic.

Hi Dominique,

here's a small article about the properties of PVC:

...The addition of plasticizers allows the hardness and toughness of PVC vary good. It can be dyed. PVC absorbs water, is resistant to acids, alkalis, alcohol, oil and gasoline. PVC is attacked by acetone, ether, benzene, chloroform, and hydrochloric acid. Rigid PVC can be good, soft PVC handle poorly machined. At temperatures of 120 - 150 ° C can be deformed without cutting it. Connections can be made ​​with a special adhesive or by welding with hot air...

I hope it is helping you


smurfy greetings

Thank you, Benny.

I do agree with the info Benny has shared, and believe me, Dom...I am an expert in NOTHING!!!!!Jejejeje. I left the chemistry many years ago. Of course I do know the most important things a chemistru would know but things go so fast in sciences that sometimes I have the impression I studied Chemistry at XIX century

Thank you Joaquin. (Don't bother though, my brother. )

I also am no expert at this stuff. I just want to point out that the article is talking about PVC pipe and not Smurfs, Nor does it refer to the paint that is used on Smurfs. I certainly will not be the one testing my Smurfette batter to see if acid will hurt PVC.
