Polyurethane Foam Materials Coloring

Specialized in the field of polyurethane foaming

The series coloring agents are our company's main macromolecular coloring agents used in the foaming field. They are liquid coloring agents with good fluidity and advantages that traditional colorants cannot match in their corresponding substrates. They do not require grinding, are easy to disperse, resistant to migration, do not settle or layer, are easy to clean, have bright colors, and have 3-5 times the color strength of traditional colorants. The product has passed the EU EN71-3/9 safety testing certification, does not contain heavy metals, and is safe and environmentally friendly. This series of colorants reacts directly into the chemical structure in the form of polyols in the foaming formula system, and the dyes do not migrate out of the sponge. It is a new type of green, safe, and environmentally friendly colorant.

Product Features

Low addition ratio: The color intensity is 3-5 times that of the color paste.
No migration: Liquid colorants can directly participate in the reaction without migrating out.
No precipitation: uniform state, completely miscible, no need for continuous stirring before use.
Colorful/Rich: Low addition can minimize the impact on the physical properties of the finished product and the amount of catalyst used.
Strong universality: Suitable for polyether and polyester polyurethane systems.
Non solid particle/non abrasive equipment: low viscosity, 100% homogeneous liquid non abrasive conveying and metering system. Green and environmentally friendly: The product has passed the EU EN71-3/9 safety testing certification, does not contain heavy metals, and is safe and environmentally friendly.

The series colorants revolutionize the field of foaming materials, addressing issues like poor migration resistance in traditional color blending and color agglomeration in coatings. They don't interfere with foam formation or catalyst efficiency and prevent coking, thus providing high stability. They don't cause issues like foam needle holes, color marks, or cracks, and they exhibit excellent dispersibility. With multiple hydroxyl groups, they can react chemically with isocyanates in polyurethane, ensuring excellent compatibility with polyols.
