Ultimate ETERNATHANE® polycarbonate-based polyurethane prepolymers are emerging as a promising alternative to Hydrogenated Nitrile Butadiene Rubber (HNBR) in various applications. The key advantage of ETERNATHANE® lies in its exceptional technical resistance. This is primarily due to the inherent strength of the polycarbonate component, which imparts superior mechanical properties to the resulting polyurethane.
When formulated into polyurethane as alternative to HNBR, these prepolymers exhibit enhanced durability, resilience, and thermal stability compared to traditional materials. This makes them particularly suitable for demanding environments where high performance is crucial.
HNBR has several advantages, such as its resistance to high temperatures, tensile strength, and excellent resistance to oil, fuel, and other chemicals. However, when compared with PU based on ETERNATHANE® polycarbonate-based polyurethane prepolymers, some potential disadvantages may arise:
- High-Temperature Performance: Although HNBR has good resistance to high temperatures, PU based on ETERNATHANE® polycarbonate-based polyurethane prepolymers may offer superior performance under high-temperature conditions due to the inherent resistance of the polycarbonate component.
- Versatility: ETERNATHANE® polycarbonate-based polyurethane prepolymers allows for a wide range of customization options to the final PU elastomer, enabling the development of tailored solutions to meet specific application requirements. This versatility may not be as available with HNBR.
- Technical Resistance: ETERNATHANE® polycarbonate-based polyurethane prepolymers, when formulated into polyurethane, exhibit enhanced durability, resilience, and thermal stability compared to traditional materials like HNBR.
Summarizing, the versatility of ETERNATHANE® allows for a wide range of customization options, enabling the development of tailored solutions to meet specific application requirements. Therefore, the adoption of ETERNATHANE® can lead to significant improvements in product performance and longevity, making it a viable and advantageous alternative to HNBR.
