Thermo PU leather (also known as heat-reactive or thermo reactive polyurethane synthetic leather, heat-stamping color-change PU, or color change PU leather) is a premium synthetic leather material featuring heat-induced color change. It is widely used in high-end packaging, notebook covers, menu covers, bookbinding, gift boxes, and related applications.   I. Key Features · Heat-Stamping Color Change:​ When heat-pressed at 160–180°C, the pressed areas undergo a permanent darkening effect (e.g., red to deep red, green to dark green), creating a high-contrast, embossed look similar to genuine leather branding. · Soft Touch:​ Combines the hand-feel of natural leather with the consistency and stability of synthetic materials. Offers excellent fold resistance, abrasion resistance, and anti-mildew properties. · Eco-Compliance:​ Mainstream products comply with international environmental standards including REACH, RoHS, and CA Prop 65 etc. Some carry Vegan certification and contain no animal-derived ingredients.   II.  Applications Application Area Typical Products Bookbinding & Stationery Hardcover books, notebooks, journals, photo albums, certificate covers Premium Packaging Jewelry boxes, watch boxes, wine gift boxes, presentation packaging Hospitality & F&B Menu covers, key card holders, hotel amenities Small Leather Goods Cardholders, passport covers, keychains, pouches III. Processing Guidelines · Heat-Pressing Temperature:​ Typically 160–180°C. Lighter-colored materials may require higher temperatures. Black and white variants show minimal color-change effect. · Pressure Control:​ Insufficient pressure results in poor contrast and lack of depth; excessive pressure may cause edge scorching or base texture bleed-through. · Stamping Die Material:​ Copper dies are recommended for more stable heat conduction; zinc dies are also usable but yield slightly inferior results.   IV.
