For high-end polyurethane applications where performance is non-negotiable, PPDI-based low-free prepolymer (CPU) stands out as a premium solution.
PPDI systems are known for their excellent thermal stability, high mechanical strength, and outstanding dynamic performance. By adopting a low-free PPDI polyurethane prepolymer design, manufacturers can further enhance processing safety while maintaining exceptional elastomer properties.
PPDI-based low-free CPU is especially suitable for high-speed rollers, precision industrial wheels, automotive and machinery components, where low heat build-up, high load-bearing capacity, and long service life are required.
Both polyether-based and polyester-based PPDI low-free prepolymers can be tailored to specific performance needs, offering flexibility in formulation design. The result is a polyurethane elastomer with superior fatigue resistance, abrasion resistance, and dimensional stability.
For customers targeting high-value markets and premium polyurethane products, PPDI-based low-free prepolymer (CPU) provides a strong technological advantage and long-term competitiveness.
