Here the thermal conductivity for rubber is given at about 0.14 W/(m K):
http://www.monachos.gr/eng/resources/thermo/conductivity.htm I notice that Rick Cantwell used 0.2 W/(m K): http://www.youtube.com/watch?v=yXTl8z_2Uqo Anyone have a reference to a better number than 0.14 W/(m K). Best regards, Horace Heffner http://www.mtaonline.net/~hheffner/
