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.
Polyurethane (PU) shoe molds are prized for exceptional abrasion and tear resistance, ensuring a long production life. Their high flexibility allows for easy demolding of complex designs with deep undercuts and fine details. They offer superb chemical resistance to common shoe materials, maintaining dimensional stability. PU provides high-fidelity reproduction of intricate textures and patterns, guaranteeing consistent product quality. These durable and cost-effective molds are primarily used for PU injection molding of midsoles and outsoles, thermoforming components, and creating functional prototypes for athletic, safety, and casual footwear.

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.
