TDI-100/Polyester Polyurethane Prepolymer Shore A95
1. Description
This is a TDI-100 based Polyester polyurethane prepolymer.
2. Characteristics
3. Applications
4. Typical properties
| Type | Appearance | Viscosity(mPa.s/85℃) | NCO% | Packing(kg/drum) |
| Solid | 1100-1200 | 5.00-5.20 | 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.
