Q1: What is the primary application domain for ABT-2198?
A: ABT-2198 is a thermoplastic polyurethane elastomer specifically engineered for high-performance flexible film and sheet applications, including protective coatings, inflatable components, and soft-touch overmolding—particularly where excellent melt processability and low-temperature flexibility are required.
Q2: Is ABT-2198 suitable for extrusion and thermoforming processes?
A: Yes—ABT-2198 exhibits good melt stability and uniform melt viscosity, making it well-suited for cast film extrusion, blow film, and vacuum or pressure thermoforming. Optimal processing typically occurs within standard TPU temperature ranges without requiring specialized equipment modifications.
Q3: How does ABT-2198 compare to conventional polyester-based TPUs in terms of hydrolytic stability?
A: As a polyether-type TPU, ABT-2198 offers significantly enhanced resistance to hydrolysis compared to many polyester-based alternatives—making it preferred for long-term outdoor use or humid environments where moisture exposure may affect mechanical integrity.
Q4: Can ABT-2198 be blended with other polymers?
A: ABT-2198 demonstrates reasonable compatibility with certain engineering thermoplastics such as PC and ABS in targeted alloy formulations; however, compatibility should always be verified experimentally for each intended blend ratio and end-use requirement due to potential phase separation risks.
Q5: Does ABT-2198 require drying before processing?
A: Yes—like most TPUs, ABT-2198 is hygroscopic and must be thoroughly dried prior to melt processing. Recommended drying conditions are typically 80–90 °C for 3–4 hours using dehumidifying or hot-air dryers to achieve moisture content below 0.05%.
