Have you ever used PVC pipes in your home or school project? Then, you should know about the inventor of PVC, Waldo Semon. PVC, also known as polyvinyl chloride, is a plastic material that is durable, easy to handle, and resistant to weather and corrosion. Today, it is commonly used in plumbing, electrical wiring, vinyl flooring, and other applications.
But, did you know that PVC was accidentally discovered by Waldo Semon in the 1920s? He was a chemist working at the B.F. Goodrich Company in Ohio, where he experimented with various compounds to create rubber products. Through his innovative spirit, Waldo Semon discovered PVC and revolutionized the plastic industry. Here’s his inspiring story of how he invented PVC against all odds.
Section 1 – Early Life:
Waldo Semon was born on September 10, 1898, in Demopolis, Alabama, USA. His father, John Semon, was a farmer, and his mother, Mollie Semon, was a schoolteacher. Waldo was the youngest of nine children, and his family was struggling financially. Despite that, Waldo showed an interest in science and engineering from an early age.
He attended the University of Washington and graduated with a Bachelor of Science in Chemical Engineering in 1919. Later, he obtained a Ph.D. in Organic Chemistry from the same university in 1923. After that, he worked briefly at DuPont before joining B.F. Goodrich Company as a research chemist.
Section 2 – Rubber Research:
At B.F. Goodrich, Waldo Semon worked on several projects related to rubber research. He wanted to find a synthetic substitute for natural rubber, which was in high demand during World War II. However, his experiments resulted in failures, and he faced criticism from his colleagues for his unorthodox approach.
Section 3 – The Discovery of PVC:
Waldo Semon’s breakthrough came in 1926 when he accidentally combined vinyl chloride gas and a solvent and created a new plastic material. He initially dismissed his discovery as a failure, but later realized its potential after conducting further experiments.
The new plastic material was durable, lightweight, and weather-resistant, making it ideal for a wide range of applications. Semon called it PVC or polyvinyl chloride and filed for a patent in 1930. However, it was only in the 1950s that PVC became a widely popular material for pipes, wires, and other products.
Section 4 – Impact on the Plastic Industry:
Waldo Semon’s discovery of PVC was significant because it led to the development of other plastic materials and transformed the industry. PVC was cheaper and more functional than other materials like metal and wood, and it soon became the go-to material for various products.
Today, PVC is one of the most widespread materials used in construction, manufacturing, and packaging. From pipes and tubes to vinyl flooring and window frames, PVC has become an integral part of our daily lives.
Section 5 – Awards and Recognition:
Waldo Semon’s contributions to the plastic industry were significant, and he received plenty of awards and honors during his lifetime. In 1973, he was inducted into the National Inventors Hall of Fame, and in 1985, he received the Charles Goodyear Medal for his groundbreaking PVC discovery.
