Product Category Features
- Wide chemistry selection including polyether, polyester, and MOCA blends.
- Fine-tuned hardness control for both low-durometer and high-durometer systems.
- High resilience and tear strength in elastomer end-products.
- Compatibility with TDI/PTMEG ether prepolymers and blends with BDO.
- Options for industrial applications including paper industry couch rolls, low durometer industrial rolls, and custom castings.
- Low-color formulations for applications requiring aesthetic clarity.
Typical Uses
- Industrial rolls (e.g., couch rolls in paper mills, low-durometer rolls with resilience and tear strength).
- Blending with BDO for tailored elastomer performance (PC 90-20 and PC 90-25).
- Adjusting hardness in TDI/ether systems (PC 90-37, MOCA/DMF blends).
- General elastomer processing requiring balanced mechanical and dynamic properties.
- Specialized cast elastomer manufacturing where control over resilience, compression set, and hardness is critical.
