Polyurethane Dispersions

Overview of Water-Based Polyurethane Dispersions

Water-based polyurethane dispersions (PUD) offer superior performance when compared to solvent-based polyurethanes. These eco-friendly PUD systems exhibit excellent properties, including optimal viscosity, flexibility, non-toxicity, non-flammability, high mechanical resistance, and thermal stability across a wide temperature range.

PUD systems are widely used in various industries, including textiles, technical textiles, footwear, leather, sponges, sandpaper, EVA, furniture, floor coatings, and insulation membranes. The chemical structure of each polyurethane dispersion plays a crucial role in determining its performance in these applications.

Types of Polyurethane Dispersions:

1. Polycarbonate Polyol-Based PUD Systems:
   • High adhesion strength
   • Superior gloss
   • Exceptional hydrolysis resistance
2. Polyether Polyol-Based PUD Systems:
   • High hydrolysis resistance
   • Excellent chemical resistance
   • Enhanced flexibility
3. Polyester Polyol-Based PUD Systems:
   • High adhesion strength
   • Optimized hardness for various applications
4. Bio Polyol-Based PUD Systems:
   • Environmentally friendly
   • Comparable performance to conventional systems

Versatile and Customizable:

Polyurethane dispersions can be modified into various derivatives depending on the raw materials used, allowing for tailored solutions to meet specific industrial needs.

Key Advantages of Water-Based Polyurethane Dispersions:

• Eco-Friendly and Non-Toxic: PUD systems are non-toxic and non-flammable, making them safer for the environment and human health.
• Flexible Formulation: They offer excellent flexibility and can be customized for different viscosity levels and mechanical properties.
• High Performance: PUD systems provide strong adhesion, chemical resistance, and hydrolysis resistance, outperforming many solvent-based alternatives.
