در سال ۱۹۲۶ والدو سیمون از بی‌اف گودریچ روشی برای نرم کردن پی‌وی‌سی به‌وسیلهٔ مخلوط کردن آن با افزودنی‌های گوناگون گسترش داد. نتیجه ماده‌ای انعطاف‌پذیر بود که به سادگی در فرایندها شرکت می‌کرد و به سرعت در استفاده‌های تجاری شایع شد.
Have in mind, PVC board just isn't significantly robust By itself, so it will need a foundation or support technique to prevent bending or breaking.
Expanded maritime PVC board or expanded PVC is usually a kind of PVC that's been expanded by using a Distinctive foaming agent to boost the thickness of the material while decreasing its density. The foaming agent has become A part of the design purposefully to cut back simply how much plastic is applied.

Poly(vinyl chloride) (PVC) has been an interesting issue for polymer science analysis. Its features are heightened by its inherent structural faults ensuing from direct production (by no cost-radical polymerization), which also trigger its thermal instability. Many of the basic restricting features of PVC have already been instructed to be alleviated by improved chemistry through PVC synthesis, in addition to the use of the two inorganic and natural and organic thermal stabilizers. The traits, characterization, modification, recycling, and a variety of apps of PVC are all examined in this paper along with the previous and most recent investigation discoveries. It has been proposed that many of the basic restricting Attributes of PVC might be lessened by making use of both of those inorganic and organic thermal stabilizers together with improved chemistry for the duration of PVC manufacture.
Packaging: PVC’s versatility and resistance to oil and grease help it become a superb option for food items packaging.
Though PVC has several advantageous uses, it also has an important environmental effects. The generation and disposal of PVC may result in the release of dangerous chemicals into the ecosystem. Also, resulting from its toughness, PVC waste can persist in the ecosystem for prolonged intervals.
