365 Day Energy Gratitude Project. Day 48: Polyvinyl chloride (PVC) Derived primarily from naphtha or natural gas. Wire and cables sheathed with PVC prevent potentially fatal electrical accidents. In hospitals around the world PVC medical tubing – which does not break or kink – delivers fluids and medicines to the sick. In everyday life, they are all around us, from construction profiles to medical devices, from roofing membranes to credit cards, from children’s toys to pipes for water and gas. Most PVC products are long lasting – up to and over 60 years. These applications are reliable throughout their service lives and cut down vastly on maintenance or repair. Modern cars, for example, last many years longer simply because PVC protects the underside from water and corrosion. In the modern vernacular, PVC makes things more Sustainable. And PVC, like fossil fuels themselves has an excellent ratio of economic cost to performance, it allows people of all income levels access to these important benefits lifting the standard of living for all.
