General description
Poly(vinyl chloride) (PVC) is a commercially sold thermoplastic material with excellent physical properties. It can be used for a variety of applications such as water purification and artificial muscle structure.
Application
- Environmental Stability of PVC: Study on the environmental stability of poly(vinyl chloride) modified by Schiff′s base, highlighting its resistance to UV light (Ahmed et al., 2021).
- Mechanical Properties of PVC Nanofibers: Research on the effects of polymer concentration on the morphology and mechanical properties of electrospun cellulose acetate and PVC nanofiber mats (Tarus et al., 2016).
- Photostabilization of PVC: Insights into the ongoing advancements in the photostabilization of PVC to enhance its longevity and material stability (Yousif & Hasan, 2015).
- PVC and Mn2+ Doped Films: Investigation of the structural, thermal, and optical properties of pure and Mn2+ doped PVC films, exploring material enhancements (Kayyarapu et al., 2016).
- PVC Plasticizer Migration: A review on methods for determination of plasticizer migration from PVC materials, addressing implications for durability and material safety (Chen et al., 2022).

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
