Introduction: Synthetic leather is widely used across various industries, including automotive interiors, furniture, and fashion, due to its resemblance to natural leather, cost-effectiveness, and durability. A critical aspect of synthetic leather’s appeal is its tactile sensation, which encompasses characteristics such as softness, smoothness, elasticity, and temperature response. The choice of PU catalyst can significantly influence these properties, thereby affecting user experience. This paper aims to elucidate the relationship between PU catalysts and the tactile sensation of synthetic leather.
