To carry out the test you will need a small propane torch and a copper wire (a penny could also be used). Copper by itself burns cleanly but produces a green flame (copper chloride) when combined with a compound containing chlorine ( e.g., PVC)</font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2"><b>Steps:</b></font></font></p><p><font face="Verdana"><font size="2">Heat the copper wire in the flame of the torch until it burns cleanly. This serves to burn off any unwanted residues that might be on the wire. Make sure that you hold the wire with pliers or an insulator to avoid injury. Touch the hot wire to the holder. Some of the holder will melt and be stuck to the wire. Be sure to hold the holder close to the air intake of the torch in order to draw away the fumes from the burning plastic. Put the wire back into the flame. If the flame bums yellow or clear, no PVC present. If the flame burns bright green, then some PVC is present.</font></font></p><p>&nbsp;</p><p><font face="Verdana"><font size="2">Or</font></font></p><p>&nbsp;</p><p><font face="Verdana"><font size="2"><b>Stretch Test</b></font></font></p><p><font face="Verdana"><font size="2">For the stretch test, pull on the plastic and determine how easy it is to stretch it. The tear test is similar. Try to tear the plastic film as you would a piece of paper.</font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2"><b>Steps:</b></font></font></p><p><font face="Verdana"><font size="2">Polyester (MylarTM) hard to stretch hard to initiate a tear; once tear begins material tears easily; tear has a rough edge </font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2">Polypropylene easier to stretch than polyester hard to initiate a tear; once tear begins material tears easily; tear has a clean edge similar to cellophane </font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2">Polyethylene easier to stretch than polyester hard to tear tends to tear in directions </font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2">Polyvinylchloride easier to stretch than polyester moderately easy to initiate a tear ragged tear edge </font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2">&nbsp;</font></font></p><p><font face="Verdana"><font size="2">I now use </font></font>E&amp;T Kointainer Saflip </p><p><font face="Verdana"><font size="2"><a href="http://www.brent-krueger.com/howtopvc.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.brent-krueger.com/howtopvc.html" rel="nofollow">http://www.brent-krueger.com/howtopvc.html</a></font></font></p><p><font face="Verdana"><font size="2"></font></font>[/QUOTE]</p><p><br /></p>
