Since PVC is somewhat porous and hygroscopic, I think the Microwave Test might give false results unless the PVC were properly dried first.... ----- Original Message ---- From: Tesla list <tesla@xxxxxxxxxx> To: tesla@xxxxxxxxxx Sent: Tuesday, January 9, 2007 5:56:52 PM Subject: PVC Original poster: StephenTetorka@xxxxxx Certain PVC formulations contain heavy metals which are used to stabilize the material...Cadmium and Lead are two such metals. An easy way to determine if a PVC has metal is to put the material in a microwave oven...say 1 to 2 minutes....if it gets hot ( some of my samples actually melted )...that PVC indeed has metal in it. Note: the frequency of my mobile loading coil changed after placing the PVC cover over the assembly....it got hot in the microwave. Also...dielectric constant for "PVC" is around 4...FYI...wonder has this changes with formulation?? Kind regards, Steve WA2TAK __________________________________________________ Do You Yahoo!?
