It seems like vinyl is in almost everything. What exactly is vinyl and is it safe to be around?
Vinyl Chloride: National Emission Standards for Hazardous Air Pollutants
“The purpose of the national emission standard for hazardous air pollutants (NESHAP) is to minimize vinyl chloride emissions from process and fugitive emission sources in ethylene dichloride, vinyl chloride and polyvinyl chloride production categories to the level attainable with best available control technology… EPA decided to regulate vinyl chloride because it has been implicated as the causal agent of angiosarcoma and other serious disorders, both carcinogenic and noncarcinogenic.”
The PVC Production Process Explained
“PVC production usually refers to the manufacture of PVC resin, which is the basis for the plethora of PVC products around us. Three types of PVC manufacture exist: suspension polymerisation, emulsion polymerisation and bulk polymerisation. PVC made from suspension is by far the most common.”
“The world’s most versatile plastic had a rather humble beginning: A rubber scientist during the early 1920s stumbled onto a new material with fantastic properties during his search for a synthetic adhesive. Waldo Semon was intrigued with his finding, and experimented by making golf balls and shoe heels out of the versatile material called polyvinyl chloride, or PVC.”
