Ultralast® becomes a replacement for more exotic elastomers, such as polyether block amine elastomers (PEBA), copolyester ethers (COPE), fluoroelastomers (FKM) and hydrogenated nitrile butadiene rubber (HNBR).
Performance Advantages
- Increased durability in harsh conditions
- Longer component life
- Higher temperature performance
- Cold temperature toughness
- Better chemical resistance
- Superior dynamic properties
- Better abrasion, tear resistance and wear
Processing Advantages
- Lower required processing temperatures compared to conventional TPUs, while providing higher in-use temperatures
- Improved thermal stability for reduced cycle times, easier de-molding and better aesthetics
- Can be injection molded and extruded into complex geometries
Applications
A broad range of Ultralast® TPU grades with different hardness and chemical backbone are available to cater the needs of different demanding applications. Tailor-made solutions are also possible and sustainability plays a key role in the product development. “We strive to innovate and to be attentive to fast changing world demands. LANXESS Urethane Systems is now working to incorporate bio-based polyols in its Ultralast® portfolio, contributing to a more sustainable world through carbon footprint reduction.
Ultralast® TPUs have proven their value in demanding applications, and have enabled parts including oil & gas mud pump pistons and hydraulic seals, to have their lifetime considerably extended and sometimes doubled. Other equally challenging applications such as valves, mining screens, pump liners and all sorts of seals exposed to harsh environments, greatly benefit from Ultralast® technology.
