Pu Foam Pigment is a pigment used in polyurethane foam that can impart rich colors to polyurethane foam products. Its working principle mainly involves the dispersion and adsorption of pigments.
Dispersion: The pigment molecules in Pu Foam Pigment have good dispersion and can be evenly dispersed in the polyurethane foam system. This is because the surface of the pigment molecules has hydrophilic or hydrophobic groups, which interact with the molecules in the polyurethane foam system to achieve dispersion.
Adsorption: The pigment molecules in Pu Foam Pigment can interact with the molecular surface of polyurethane foam and adhere to the foam surface through physical or chemical adsorption. This adsorption can firmly fix the pigment on the foam surface and prevent it from falling off easily.
Through dispersion and adsorption, Pu Foam Pigment can evenly disperse pigment colors in polyurethane foam and firmly adhere to the foam surface. In this way, the polyurethane foam products can show a variety of colors.
It should be noted that the working principle of Pu Foam Pigment may vary depending on the specific product, and the specific formula and process conditions will also affect its performance. Therefore, when using Pu Foam Pigment, it is recommended to select the appropriate pigment according to the specific situation and follow the relevant production process requirements.
