A Surprising Use for Salt!?
We use salt every day of our lives, but in fact it can also be used to make plastic.
The plastic we make from salt is called "polyvinyl chloride (PVC)." It is used in a lot of things, from the pipes that carry our drinking water or for reinforcing power lines to medical equipment such as transfusion bags. Thanks to PVC, we can drink safe water, live comfortable lives each day, and get worry-free medical treatment. In addition, PVC finds many uses as materials in all sorts of daily products, and as construction materials for cars or houses. In fact, the plastic erasers children love are also made from PVC.
Where PVC excels is the fact that more than half of its ingredients is salt (raw salt), so we can keep the use of precious oil to a minimum. Also, the processable and flame-retardant nature of PVC can also help reduce the risk of fire when used in wallpaper or curtains.
In spite of these advantages, people used to complain that PVC harmed the environment when it was burned. But this misunderstanding has been cleared up thanks to the presentation of data and other activities by the Vinyl Environmental Council and other groups, and its effectiveness is starting to be recognized. Recently, we have seen a rapid expansion of use in airtight plastic sashes through Housing Eco-Points, and these sashes actually use PVC.
Kaneka started mass production of PVC more than sixty years ago, in 1950. Since then, we have continued to expand as one of the top-class manufacturers of PVC. The PVC manufacturing equipment we used for mass production back then is some of the oldest in Japan, and was registered by the National Museum of Nature and Science as one of the Essential Historical Materials for Science and Technology in 2013.
In our more than six decades of manufacturing history, Kaneka PVC has been given a range of added functions. In particular, our special PVC resins are being expanded around the globe, with manufacturing bases in the United States and Asia. We will continue to support convenient and comfortable lifestyles through the technology and expertise we have attained over the years.
