Product Description
Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity.
This prepolymer is engineered to deliver exceptional comprehensive properties, including outstanding tensile strength, high elasticity, and superior resistance to abrasion, oils, and solvents. It effectively addresses the common failures of traditional elastomers, such as becoming brittle and cracking, especially after prolonged exposure to harsh chemicals. Products formulated with this prepolymer exhibit significantly extended service life and performance that meets or surpasses that of leading international brands, making it the ideal choice for manufacturing high-performance, long-life industrial rollers and wear-resistant parts.

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. Sieve plate/Screening Panels: Used for vibrating screens in mining, coal, and metallurgy industries; wear-resistant and low-noise.
2. Scraper Blades/Doctor Blades: Used for cleaning conveyor belts, printing machinery, and agricultural equipment; wear-resistant and non-damaging to substrates.
3. Shoe Soles: Particularly for industrial safety boots and high-end durable soles, providing long-lasting wear protection.
4. Molds: Primarily used as flexible molds for manufacturing composite materials (e.g., fiberglass), offering easy demolding, dimensional stability, and long service life.
