Low Free Polyurethane NDI Series NDI/PCL LFNE4395 Low Free Prepolymers
1. Description
LF NDI polyurethane prepolymer is produced by a low ionization process, which can effectively reduce the adverse effects of reaction heat release compared with the traditional process. The prepared prepolymer has a lower viscosity and can be stably stored for more than 12 months. NDI elastomers can improve the processing performance while improving the degree of microphase separation of elastomers, and can give full play to the performance of NDI products under dynamic loads.
2. Application
For high-end polyurethane elastomer products.
