TDI-100/Polyether Polyurethane Prepolymer Shore A83-87
1. Description
This is a TDI-100 based polyether polyurethane prepolymer.
2. Characteristics
3. Applications
4. Typical properties
| Type | Appearance | Viscosity(mPa.s/85℃) | NCO% | Packing(kg/drum) | 
| Liquid | 300-330 | 4.50-4.70 | 20/200 | 
5. Operating Procedure
First, the prepolymer should be preheated in 80-85℃. Second, after vacumming, the prepolymer is to be mixed with melting MOCA evenly. Third, with degassing, casting into mould, and vulcanization,and then demould. Lastly, the finished product should be post vulcanized.
