Nanomed MAX Compounds provide molecular level reinforcement.

Press Release Summary:

Incorporating nanoclay particles into high strength nylon alloy, Nanomed MAX Compounds are platelet-shaped particles with thickness less than a nanometer. Processed using standard mold and barrel heaters, compounds enhance strength and rigidity of polymer without hindering flow into thin sections. Suitable for medical device components, units are based on meta-xylene diamine polyamides to withstand to gamma, e-beam and ethylene oxide sterilization.

Foster Introduces Nano Reinforced Nylon Alloys for Structural Medical Components

Foster Corporation, a leader in polymer solutions for healthcare markets, introduces Nanomed MAX® compounds for medical device components that require high strength, yet cannot use metals or traditional reinforced plastics. These compounds, based on an alloy of meta-xylene diamine polyamide (MX nylon), are United States Pharmacopeia (USP) Class VI tested and suitable for reusable instruments or components that must withstand gamma, e-beam and ethylene oxide sterilization.

Minimally invasive procedures are increasingly used throughout the healthcare industry. New procedures require instruments, fixtures and components that do not interfere with magnetic resonance imaging (MRI), computerized axial tomography (CAT), fluoroscopy, and x-ray imaging. Metals are not suitable and plastics often require reinforcing additives, such as glass fiber, to provide sufficient strength for structural components. However, these traditional additives are too large for molding or extruding intricate device components with thin wall sections. Unreinforced, high strength plastic options, such as polyetheretherketone (PEEK), are often cost prohibitive.

Nanomed MAX compounds incorporate nanoclay particles into a high strength nylon alloy. These platelet-shaped particles, less than a nanometer thick and up to 1000 times greater in surface diameter, provide reinforcement at the molecular level. This enhances strength and rigidity of the polymer without hindering flow into thin sections. Nanomed MAX compounds include less than 10% by weight nanoparticles resulting in 15% more tensile strength than unmodified PEEK, for approximately half the price.

“Unlike PEEK, Nanomed MAX compounds do not require the high temperature injection molding or extrusion equipment,” said Larry Johnson, Executive Vice President for Foster Corporation. “These alloys can be processed using standard mold and barrel heaters that are commonly used for nylons and polyesters.”
