PVC in its native state is fairly rigid. Flexible PVC ("Vinyl") is made by adding plasticizers to the material. In the old days, compounds such as octyl phthalate were simply added into the mix and would slowly leach out or evaporate over time; this is why old vinyl used to get brittle after a while. The modern method is to introduce internal plasticizers which are actually part of the (mostly) PVC molecule; these cannot leach out and keep the vinyl flexible.

Is PVC a compound or mixture?
PVC is a compound, not a mixture. It is made up of long chains of repeating units of vinyl chloride molecules, which are chemically bonded together to form a single substance with consistent properties.
Does calcium carbonate melt while processing a PVC compound?
No, calcium carbonate does not melt during processing of a PVC compound. It is added into the compound as a filler to improve properties like stiffness and impact resistance. It acts as a reinforcing agent rather than a melting component.
Why PVC is soft and flexible whereas bakelite is hard and brittle?
PVC is softer and flexible because it is a thermoplastic polymer, which means it can be easily molded and reshaped when heated. Bakelite, on the other hand, is a thermosetting polymer, which means it hardens irreversibly once molded and cannot be reshaped. This makes bakelite hard and brittle compared to PVC.
Is cotton a compound word?
No, "cotton" is not a compound word. It is a single word referring to a soft, fluffy fiber that grows around the seeds of cotton plants.
Why are plasticisers added to PVC?
Plasticizers are added to PVC (polyvinyl chloride) to increase its flexibility, durability, and workability. They help to make the PVC material more pliable and easier to process during manufacturing. Additionally, plasticizers can enhance the overall performance and properties of PVC products.

What makes PVC soft?
PVC (polyvinyl chloride) becomes soft when plasticizers, such as phthalates or adipates, are added during its formulation. These additives reduce the polymer's intermolecular forces, making it more flexible and easier to process. The resulting soft PVC is often used in applications like upholstery, flooring, and electrical cable insulation, where flexibility and durability are essential. Without plasticizers, PVC remains rigid and brittle.
How do you connect PVC to soft underground water pipe for a inground pool?
purchase a threaded connector, for the PVC pipe, then purchase a metal threaded adaptor for soft pipe, see your hardware man,
What is chemical formula for PVC compound?
poly-vinyl chloride
How can you decrease density of PVC compound?
To decrease the density of a PVC compound, you can add fillers or extenders such as calcium carbonate or clay. These materials will help to displace some of the PVC resin, reducing the overall density of the compound. Additionally, you can also reduce the amount of PVC resin in the formulation and replace it with lower density materials to achieve the desired density.
Is PVC a compound or mixture?
PVC is a compound, not a mixture. It is made up of long chains of repeating units of vinyl chloride molecules, which are chemically bonded together to form a single substance with consistent properties.
