Considerations Affecting Biodegradability of Vinyl

摘要

Polyvinyl chloride is one of the most useful materials available to the fabricator, being capable of formulation so as to produce a range of forms from soft coatings to durable structural articles. Vinyl combines good physical properties, chemical, flame, abrasion and weathering resistance with low cost. It has, nevertheless, been subject to strong non-economic competition based on the allegedly evil effects of chlorine. Thus articles are promoted as "halogen free," despite the fact that in the absence of chlorine, all life on earth would cease.
