PU self-skinning foam sponge is a versatile material that finds applications in various industries. This article aims to provide a comprehensive overview of its properties, manufacturing process, and diverse applications. From automotive to furniture, this foam sponge offers unique advantages that make it a preferred choice for many manufacturers.

Understanding PU Self-Skinning Foam Sponge

Definition and Composition:

PU self-skinning foam sponge, also known as polyurethane self-skinning foam sponge, is a type of foam material that possesses a dense outer skin and a lightweight, flexible inner core. It is composed of a polyurethane matrix, which is formed by the reaction of polyol and isocyanate.

Manufacturing Process:

The manufacturing process of PU self-skinning foam sponge involves several steps. Firstly, the polyol and isocyanate are mixed together to form a liquid mixture. This mixture is then poured into a mold, where it undergoes a chemical reaction, resulting in the formation of foam. The foam expands and fills the mold, creating the desired shape. The outer skin is formed due to the reaction of the foam with the air, creating a dense and durable surface.

Properties of PU Self-Skinning Foam Sponge
