VESTAMID? Care ML21
聚酰胺12
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 :
