Q1: What are the key processing advantages of Taiwan Hongyi 98AE compared to conventional TPU grades?
A: Taiwan Hongyi 98AE offers enhanced melt flow and reduced viscosity during extrusion and injection molding, enabling smoother processing at lower temperatures and shorter cycle times. Its balanced hardness and elasticity also support excellent dimensional stability and surface finish in thin-walled or complex geometries.
Q2: Is 98AE suitable for applications requiring long-term flexibility and low-temperature performance?
A: Yes — as an aliphatic polyester-based TPU elastomer, 98AE maintains good elasticity, resilience, and crack resistance down to approximately −30 °C. It is commonly selected for dynamic components exposed to repeated flexing or thermal cycling in outdoor or automotive environments.
Q3: How does 98AE perform in terms of hydrolytic stability and UV resistance?
A: Due to its aliphatic structure and optimized polymer architecture, 98AE exhibits superior hydrolytic stability compared to many aromatic TPUs, especially under warm, humid conditions. It also demonstrates good inherent UV resistance without requiring additional stabilizers, making it suitable for non-pigmented or lightly pigmented outdoor applications.
Q4: Can 98AE be blended with other thermoplastics or elastomers?
A: Yes — 98AE shows favorable compatibility with several engineering thermoplastics such as PC, ABS, and certain polyesters, particularly when used as a toughening modifier. Compatibility should be verified experimentally for each specific blend system, and compatibilizers may be recommended for optimal phase dispersion and mechanical performance.
