Bisphenol A
BPA is sometimes used as an antioxidant in phthalates, [57] which are extensively used as plasticizers for PVC. BPA has also been used as an antioxidant to protect sensitive PVC heat stabilizers.
What is BPA? Should I be worried about it? - Mayo Clinic
BPA stands for bisphenol A, an industrial chemical that has been used to make certain plastics and resins since the 1950s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. They may also be used in other consumer goods.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers may comprise 15–50% of a PVC formulation. By changing type and amount of plasticizer, properties can be tailored to requirements. Increasing plasticizer concentration increases flexibility, decreases tensile strength, and reduces hardness (e.g., Figure 1 ).
Poisoned by Plastic: A Closer Look at HPLC Analysis of BPA
AM: The HPLC analysis is fast, occurring in under 6 minutes. The polymeric columns are great for applications like this because of their durability, overall structural stability, and ability to be easily regenerated, if needed. The column can be used to quickly analyze multiple samples per hour.
It's the Rheo Thing: BPA is not a plasticizer
Plasticizers are compounds that are added to an existing plastic to make it more plastic-y (meaning able to undergo irreversible deformation). They are commonly phthalates, but they can be other compounds as well. BPA on the other, is a monomer, which when reacted with other monomers produces a plastic. It does not change the properties of an
- What is BPA and its transformation products in air?
- Information on BPA and its transformation products in air is lacking. Bisphenol A (BPA) and its analogues are high-volume production organic synthetic compounds used in the synthesis of plastics. BPA has been categorized as an endocrine disrupting compound due to its ability to disrupt the hormonal makeup of living organisms.
- Is BPA a natural substance?
- Bisphenol A (BPA) is not a natural substance but is produced artificially during the manufacturing of various plastics. Exposure to (BPA) is a pervasive and growing concern. BPA has recently been classified as a substance of great concern by the European Union (EU). BPA is suspected to be associated with several chronic human health effects.
- How is BPA risk assessed in Korea?
- In Republic of Korea, risk assessment for BPA has been focused on relying on traditional toxicology animal studies rather than academic studies whose endpoints are more sensitive and considered appropriate.
- Is Korean BPA exposure a risk to human health?
- However, compared to the new safe level of BPA suggested by EFSA, the latest Korean BPA exposure level may be considered a potential risk to human health at all ages, although with the TDI in Republic of Korea and in agencies in other countries, the current risk remains low, and these evaluation results are confusing for risk managers.
- Are You exposed to BPA in plastic?
- As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA. The primary source of human exposure is via food, as epoxy and PVC are used to line the inside of food cans to prevent corrosion of the metal by acidic foodstuffs.
- What are the advantages of polycarbonate BPA containing plastics?
- Polycarbonate BPA containing plastics have high impact, strength, hardness, toughness, transparency, strong temperature resistance (−40 to 145 °C) and resistance to many acids and oils (Kang et al., 2006).
