VESTAMID® Care ME55
聚醚嵌段酰胺
VESTAMID® Care ME grades represent a range of flexible polyether block amide (PEBA) resins of varying hardness for processing via extrusion or injection molding. VESTAMID® Care ME materials are available as standard and bonding-modified grades.
VESTAMID® Care ME standard grades have a proven history in catheter applications. Due to their broad range of flexibility, VESTAMID® CareME grades are used in different parts of catheter constructions - may it be the distal end, requiring a low modulus for non-traumatic insertion, or the proximal end, needing a high modulus for force and torque transmission.
