The ducts, most preferably provided as plastic tubes, are characterized by inner sidewall compositions of a modified polyvinyl chloride (PVC)-based compound, the compound consisting at least predominantly of PVC polymer but additionally containing up to about 20% by weight of fluorocarbon polymers compounded directly with the PVC.
