Non solvent Eco friendly synthetic skin-feeling PU leather

Non solvent Eco friendly synthetic skin feeling PU leather for sofa furniture covers   Solvent-free synthetic leather achieves a skin feel similar to that of genuine leather through its special production process and material selection. ‌   The basic principle of solvent-free synthetic leather is to form through online rapid reaction after prepolymer mixing and coating. After the prepolymer is mixed evenly, it is injected and coated on the base cloth or release paper. After entering the drying oven, the low-molecular prepolymer begins to react, gradually forming a high-molecular polymer, and forming during the reaction process‌. This process involves complex chemical reactions, including chain growth, cross-linking reaction, and physical foaming. Among them, the chain growth reaction mainly depends on the reaction between isocyanate prepolymer and hydroxyl prepolymer, which is a key step in the formation of high molecular weight polyurethane. The cross-linking rea…
