Por-A-Thane E-70DTSR is a polyether-based TDI terminated prepolymer which yields a 70-75 Shore D hardness and low viscosity when cured with 4;4’-methylenebis-(orthochloroaniline) commonly known as MOCA.
Advantages
- Excellent humidity resistance
- Good impact strength
- Good Machinability
- High heat distortion temperature
- Low coefficient of friction
- Very high modulus and tensile strength
