VESTAMID®Care ML grades cover a range of polyamide 12 resins of different viscosity for processing via extrusion or injection molding. The VESTAMID®Care ML product range consists of unstabilized base resins as well as stabilized or reinforced compounds.
VESTAMID® Care ML resins are characterized by several outstanding properties, such as high impact & notched impact resistance, dimensional stability, good sliding properties, high abrasion resistance and resistance against chemicals.
Unfilled VESTAMID® Care ML grades are for example the materials of choice for catheters and tubings, where VESTAMID® Care ML materials meet even highest challenges in applications such as angioplasty balloon catheters.
Typical areas of application for reinforced VESTAMID® Care ML grades include housing-parts, monitoring and imaging devices and durable medical equipment. Due to their low water uptake, filled VESTAMID® Care ML grades even resist steam autoclaving for more than 500 cycles. The advantages at a glance :
High impact resistance
High dimensional stability
High chemical resistance
Low sliding friction
High toughness
High abrasion resistance
Easy processability & colorability
