Features
Polyester / TDI Based Prepolymers
- These prepolymers, in combination with amine cross-linkers, are applicable in a wide range of hardness from rubber to plastics and are applied for rolls, oil-seal, packing, gears, belts, anti-vibration rubbers, o-rings, etc. They have excellent physical properties, e.g., oil, abrasion and heat resistance.
Polyether / TDI Based Prepolymers
- These prepolymers, modified with PPG, PTG, or PPG/PTG mixture, are widely used, especially, in fields which require excellent water resistance in combination with cross-linking agents based on amines.
