#113 From Erasers to Piping, PVC Is Amazing!
In this episode, our host Kanemaru-san passionately discusses the surprising properties of "Enbi" (Polyvinyl Chloride), a ubiquitous plastic that supports our daily lives.
It is surprising that erasers and water pipes are made of the same material.
Actually, hard water pipes (PVC pipes) and soft, squishy erasers are both made from the same "Enbi." From electrical wire coatings to nostalgic vinyl records, the fact that such a diverse range of products is made from the same material highlights the wonders of chemistry.
There is a magic ingredient that controls the material's hardness.
PVC is naturally hard and brittle. By mixing in a substance called a "plasticizer," it infiltrates the gaps between molecules and allows them to move freely, creating flexibility. It is incredible that by simply adjusting the amount of plasticizer, products with completely different textures can be created.
We also explore unexpected differences with other familiar products.
In the second half, we cover the specific role of certain additives in erasers and the definitive differences between PVC and products like Saran Wrap. Your perspective on the "Enbi" we use daily might change a little. Please enjoy the full episode for a deeper dive into the world of chemistry.
