TDS / Ethers
The TDS/Ethers series includes a family of TDI/ether prepolymers widely used for hot-cast elastomers in industrial and specialty markets. Known for their high resilience, abrasion resistance, low free isocyanate levels, and processing flexibility, these materials span hardnesses from ~82A to 97A and remain among the most trusted general-purpose urethanes in the industry.
Product Category Features
- TDI/ether chemistry offering superior resilience and impact/abrasion resistance.
- Wide hardness range (~82A to 97A) covering resilient to rigid elastomers.
- Excellent processing flexibility with low viscosity and long pot life options (e.g., PC 40-90).
- Low free isocyanate levels (~0.20% in PC 40-90) for safer handling.
- Variants available with tailored NCO content for different reactivity needs.
- Well-established, proven materials with decades of use in demanding industrial applications.
Typical Uses
- Custom molded components requiring resilience, toughness, and dimensional stability
