Yes, you can glue PVC (Polyvinyl Chloride) to ABS (Acrylonitrile Butadiene Styrene), but it requires a special adhesive known as a transition cement or multi-purpose cement designed for this purpose. Standard PVC or ABS cement alone won't create a strong bond between these two types of plastic because they have different chemical compositions. The transition cement contains solvents and resins that can properly soften and bond both PVC and ABS materials, ensuring a durable connection. Always ensure the surfaces are clean and dry before applying the glue and follow the manufacturer's instructions for the best results.

Polypropylene sleeves are considered archival-safe for storing documents, photographs, and artwork. Unlike PVC (Polyvinyl Chloride), which releases harmful acids that can degrade materials over time, polypropylene is acid-free, ensuring a more stable and less reactive environment for preservation. Its inherent chemical stability, resistance to moisture, and absence of plasticizers, which can leach out and damage contents, make it an excellent choice for long-term storage. However, it’s vital to ensure that the polypropylene used is of archival quality, as not all polypropylene products are created equal. Archival-grade polypropylene sleeves are typically manufactured to stricter specifications to ensure they are free from harmful additives that could potentially compromise the integrity of stored items. In the realm of archival storage, choosing the right materials is crucial for protecting valuable items from degradation over time, and polypropylene sleeves, when certified as archival, are a reliable option.

Vinyl and PVC often refer to the same material, but context matters. Polyvinyl chloride, or PVC, is a plastic polymer widely used in various applications, from plumbing pipes to fashion items. "Vinyl" is a colloquial name often used when referring to PVC products, especially in contexts like vinyl flooring or vinyl records. In essence, vinyl is a type of PVC. The confusion usually stems from the variety of products PVC can be made into—rigid forms like pipes or flexible forms like vinyl records. Besides common uses, the terms also diverge in professional settings; for instance, in construction, "PVC" is more likely to refer to pipes, while "vinyl" may mean siding or flooring. Essentially, while all vinyl is PVC, not all PVC applications are referred to as vinyl, making the distinction more about usage context than material difference.
