Acetone can be effective in removing PVC glue, especially when the glue is not fully cured. PVC glue, also known as a solvent cement, creates a strong bond by chemically fusing the PVC materials together. Acetone, a potent solvent, can dissolve many types of adhesives and can break down the chemical bonds formed by PVC glue, making it easier to remove. However, caution is advised as acetone can also affect the surface integrity of some plastics, potentially causing damage or discoloration. It is recommended to test it on a small, inconspicuous area first. If the PVC surface is sensitive, considering a gentler removal method or consulting a professional may be preferable.

Not all page protectors are PVC-free. Page protectors, used to shield documents and photographs, can be made from various materials, including polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). PVC is known for its durability but has been criticized for environmental and health concerns due to the release of chlorine gas when burned, and the potential leaching of hazardous chemicals. Manufacturers increasingly offer PVC-free options, which are typically labeled as such, using PP or PE instead, as they are considered safer and more environmentally friendly. Consumers looking for PVC-free options should check product descriptions or packaging to ensure they are choosing the right material for their needs.
