Pvc

摘要

Poor Waldo Semon. Today the inventor would no doubt fly his private jet to his private island, where he would entertain VIPs in just about any industry you could name. But in 1926, when the B.F. Goodrich Co. researcher devised polyvinyl chloride (PVC), his employer had a hard time marketing it. Today, manufacturers in industries ranging from medical to building and products ranging from packaging to consumer goods such as automotive interiors, wall coverings, apparel and upholstery rely on PVC for its durability, flexibility, light weight and low cost. And yet this 50-year-old workhorse has detractors whose goal is to wipe it off the face of the earth.
