Thermo PU leather is a kind of high-grade leather made of special craftsmanship. It feels comfortable and has certain damping.
After this kind of leather is subjected to the thermal pressure of the hot press, the surface of the leather is subjected to a similar carbonization reaction, which imitates the imprint left by the leather after being scorched at high temperature, resulting in a deeper color gradation of the hot-pressed surface, so it is called thermo PU leather.
Production process: This is to add color-changing resin to the PU surface layer and a base layer of the leather, after infiltration. Then it is processed by release paper veneer or embossing and printing.

For example red to dark red, grass green to dark green, orange to dark yellow, earth yellow to coffee, and purple to black. It is mostly used to make notepads, diaries, and manager folders.
