Product Description
Our polyurethane prepolymers are meticulously engineered and rigorously controlled intermediates that form the essential foundation for the superior performance of your end products. We offer a diverse range of prepolymers based on MDI, TDI, and other specialty diisocyanates to meet your most demanding application requirements.
The rigid yet resilient nature of PU ensures the last maintains its precise shape consistently during production, guaranteeing a perfect fit for footwear. Its excellent abrasion resistance withstands repeated use, while its closed-cell structure provides superior moisture resistance. These characteristics ensure longevity, operational efficiency, and contribute to the consistent manufacturing of high-quality shoes with defined contours and structural integrity.

Our Advantages
- Superior End-Properties: Pre-polymerization allows us to pre-build the polymer chain structure, endowing final products with exceptional mechanical strength, abrasion resistance, elasticity, and chemical resistance.
- Processing Ease: The prepolymer route simplifies your production process. The reaction with curatives (e.g., MOCA) is more manageable and controllable, minimizing bubble formation and facilitating casting, potting, and coating.
- Formulation Flexibility: We offer a wide selection of NCO content, molecular weight, and functionality. Customization of soft and hard segments enables precise tuning of your product's hardness, modulus, and elongation.
- Consistent & Reliable Quality: Stringent process control and quality assurance ensure batch-to-batch consistency and reliability, guaranteeing stability in your manufacturing.
Other Application Areas
1. Wheels/Casters: Used for handcarts, logistics handling equipment, and industrial machinery; high load-bearing capacity, wear-resistant, and floor-friendly.
2. Sieve plate/Screening Panels: Used for vibrating screens in mining, coal, and metallurgy industries; wear-resistant and low-noise.
3. Scraper Blades/Doctor Blades: Used for cleaning conveyor belts, printing machinery, and agricultural equipment; wear-resistant and non-damaging to substrates.
4. Seals/O-rings: Used in hydraulic equipment, pneumatic tools, and automotive systems, maintaining long-term sealing performance in harsh oil-contaminated environments.
