Colorless TDI 100 Based Polyester Polyurethane Prepolymer
1. Description
This is a TDI-100 based Polyester polyurethane prepolymer.
TDI based products are less sensitive to moisture, have shorter demould times and more user friendly than MDI product.
Polyester based polyurethanes have superior cut, tear, abrasion, oil and solvent resistance.

4. Typical properties
| Type | Appearance | Viscosity(mPa.s/85℃) | NCO% | Packing(kg/drum) |
| Solid | 1800-2000 | 3.60-3.80 | 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.
6. Reaction parameters
| Item | MOCA (%) | Gel time(min) | Mixing temperature(℃) | Post vulcanization(h) |
| Specification | 10.5 | 9-10 | 85/120 | 10 |
7. Finished products properties
| Item | Hardness(Shore A) | Tensile strength(MPa) | Tear strength(KN/m) | Rebounding(%) |
| Physical properties | 85 | 46-48 | 70-75 | 39 |
8. Effects of curative level
All physical properties of elastomers are sensitive to curative level. The curative level is often expressed as % theory. The table below
shows how physical properties vary with % theory.
| Physical properties | Change |
| Hardness | Remains unchanged between 85-100% |
| Tensile strength | Maximum physical properties achieved between 90-95% theory |
| Tear strength | Maximum properties at 100-105% theory. Significantly lower outside the range |
| Abrasion resistance | Remains relatively unchanged between 85-105% theory. Slightly better at 100-105% theory. |
| Flex life | Maximum property at 100-105% theory |
| Elongation | Maximum at 100-105% theory |
| Compression set | Best at 85-95% theory |
