Description

TDI-100/Polyester Polyurethane Prepolymer Shore A90

1. Description

This is a TDI-100 based Polyester polyurethane prepolymer.

2. Characteristics

  • High oil resistance
  • Abrasive resistance
  • Good michanical performance

3. Applications

  • Sieve plate
  • Machine parts
  • Sealing ring
  • Roller

4. Typical properties

Type Appearance Viscosity(mPa.s/85℃) NCO% Packing(kg/drum)
Solid 1300-1500 4.30-4.50 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
