What is PVC primarily known for?

PVC, or polyvinyl chloride, is primarily known for its rigid and hard properties. This makes it an excellent choice for applications requiring strength and durability, such as in plumbing pipes, window frames, and flooring. The rigidity of PVC allows it to maintain its shape under stress, which is crucial in construction and various industrial uses.

While PVC can also be modified to be more flexible for certain applications, the core characteristic of standard PVC is its rigidity. It is used extensively in both construction and manufacturing for products that require structural integrity and resistance to impact.

On the other hand, the properties associated with options such as being heat resistant, pliable and soft, or biodegradable do not apply to PVC in the same way. PVC is not known for its heat resistance, as it can deform or release harmful chemicals when exposed to high temperatures. While it can be made softer and more flexible through the addition of plasticizers, this is not its primary defining characteristic. Additionally, PVC is not biodegradable, which is a significant environmental concern regarding its use and disposal.
