AI Overview
PU (Polyurethane) raw material in bookbinding refers to two distinct applications: PU leatherette (synthetic covering) and PUR adhesive (Polyurethane Reactive glue). PU leather acts as a durable, flexible covering for hardcovers, while PUR is a high-performance adhesive known for superior strength, flexibility, and lay-flat qualities compared to traditional glues.
Key PU Materials and Their Uses:
- PU Leatherette/Synthetic Leather: A synthetic material made of polyurethane resins with a woven or non-woven fabric backing (polyester, cotton, or ground leather). It is used for premium hardcovers, Bibles, journals, and menus.
