Because it needs additives like plasticizers like diethylhexyl phthalate (DEHP), among others, and produces chemicals of concern during its life cycle (manufacturing, use, and disposal), polyvinyl chloride (PVC) is a problematic plastic. Exposure to these chemicals may be hazardous.
PVC responds remarkably strongly to sunshine and other ultra violet light. Studies reveal that extended sun exposure has minimal to no impact on PVC's elasticity or tensile strength. The impact strength appears to be the only parameter that degrades.
Chlorine gas is a poisonous and volatile chemical that is produced via a highly energy-intensive process that is the beginning of PVC's life. To operate, the process needs mercury, asbestos, or extremely dangerous PFAS.
PVC Health Concerns: liver malfunction, reduced sperm count, undescended testes, cancer, birth deformities, reproductive and developmental issues, and early puberty.
safer substitutes for plastic toysTo guarantee your child has a secure play area, adhere to following recommendations: Steer clear of PVC: Don't buy anything with a resin #3 in the chasing arrows; this is readily done. However, if the flexible plastic toy isn't clearly labeled, wait to purchase it until it has the PVC-free label.
It's unlikely that pouring boiling water down the drain will clear the clog. Granted, there's a very slim chance that it will unclog the pipe, but the likelihood of softening or melting PVC joints is higher.
This can seriously damage PVC pipes and pipe seals by melting them. Boiling water can also melt the wax ring surrounding the toilet and possibly shatter the porcelain bowl, necessitating an expensive trip to your local hardware store to unclog the toilet.
Because PVC can only tolerate temperatures of up to 140°F, it is not advised for use in hot-water distribution systems, even if it works great for DWV and water service lines. Conversely, PEX and CPVC are resistant to temperatures as high as 200°F.
When people cook or drink tainted water, they run the risk of being exposed to vinyl chloride. It is possible for the skin to absorb vinyl chloride. People may come into contact with tainted water, contaminated soil, or vinyl product handling. Skin absorption is most likely a minor exposure pathway, though.
Experts state that PVC starts to break down at temperatures higher than 140°C (284°F). At this stage, the molecular structure of the polymer begins to disintegrate, releasing additional volatile organic compounds (VOCs) and hydrogen chloride gas. If these emissions are breathed in or come into contact with the skin, they may be dangerous.
