Moisture Analysis and Determination for Medical-Grade Plastics
Product Safety Means Patient Safety - Get Consistently High Quality Results Compliant to ASTM Standard D6980 with Smart Sartorius Moisture Analysis Solutions
Innovation in medical devices is often dependent on the development of the polymers and resins used in their manufacture; the inherent flexibility and low cost make polymers and resins the ideal material for many medical solutions, from stents, pacemakers, or catheters to prosthetic limbs and much more.
Patient safety must come first; therefore, resins used for medical devices are subject to stringent analysis because the quality of the final product depends the quality of the raw materials. In particular, the moisture content and potential moisture absorption of the raw material has a significant impact on the appearance and functionality of the final product.
Consistent monitoring and quality control are critical success factors in Medical Device manufacturing. This starts in the design phase and remains critical during the processing of the resins through to the injection molding phase. To obtain high-quality end products, the moisture content of the resins used to create them must lie within narrow tolerances, being neither too moist, nor too dry; either situation would have a negative impact on the resulting product. Therefore, plastic resins require monitoring and control of moisture levels or moisture absorption before the injection molding process and during pre-drying processes, if such are used.
Smart Solutions to Determine Moisture Content in Polymers and Resins
Medical grade polymers can vary in their characteristics and hygroscopic properties, and so each type of polymer needs a specific moisture content for optimal processing. Typical plastics used for safe and effective medical solutions include:
• Polysulfone | PS | • Polyethersulfone | PES |
• Polyethylene PE | • Polyurethane | PU |
• Polypropylene | PP | • Polyurethane | PUP |
• Polycarbonate | PC |
Even the smallest deviation in the specified moisture level may cause device defects and could compromise patient safety. Sartorius offers smart solutions and services to determine even the lowest moisture content in polymers and resins within minutes, offering technicians a simple workflow that guarantees reliable and accurate results and stable testing processes.
