Q1: What are the key processing advantages of EX-95A compared to conventional TPU grades?
A: EX-95A offers enhanced melt stability and lower melt viscosity during extrusion and injection molding, enabling smoother flow through fine-die profiles and improved surface finish on finished parts. Its optimized thermal profile also supports faster cycle times without compromising mechanical integrity.
Q2: Is EX-95A suitable for overmolding onto common engineering plastics like ABS or PC?
A: Yes — EX-95A demonstrates strong interfacial adhesion to a range of thermoplastics including ABS, PC, and PP when processed under appropriate temperature and dwell time conditions. Surface preparation and mold temperature control are recommended to maximize bond strength.
Q3: How does EX-95A perform in dynamic flexing applications such as cable jackets or wearable components?
A: EX-95A delivers excellent long-term flex fatigue resistance and maintains elasticity across repeated bending cycles. Its balanced hard-segment/hard-segment microstructure contributes to low hysteresis and reduced heat buildup during continuous motion.
Q4: Can EX-95A be used in medical-grade or skin-contact applications?
A: While EX-95A is formulated without known SVHCs or intentional heavy metals, it is not pre-certified for medical device or direct-skin-contact use. Customers must conduct full biocompatibility testing per ISO 10993 and validate compliance with applicable regional regulatory requirements.
