1 DuPont Performance Materials a broad range of advanced solutions for healthcare components DuPont Performance Materials delivers science-based, high quality thermoplastics to the healthcare industry. 1. These thermoplastics are used in the manufacture of demanding components across many different healthcare segments. DuPont Performance Materials a broad range of advanced solutions for healthcare components DuPont draws on its long experience in Materials research, application development, technology, safety and regulatory compliance to provide expert support to healthcare product manufacturers, backed by its Global manufacturing and supply strength. The Key Properties Our Materials Can Offer Your Products Depending on the specific High Strength First and foremost, designers are looking for an optimum application, DuPont can deliver an balance of strength, stiffness and toughness with excellent molding characteristics.

It enables the design manufacturers as they require added controls for quantity of a variety of parts and products that combine the best and placement, contamination control and add one more features of both high- Performance rubbers and flexible variable in manufacturing. plastic Materials . DuPont Performance Materials has extensive experience in Available in the range of 30 to 82 Shore D hardnesses, product development and testing for low wear and friction Hytrel is also economical to process, using a variety of applications across many industries and offers several molding or extruding technologies (See Figure 3).

DuPont Performance Materials a broad range of advanced solutions for healthcare components Chemical Inertness and Resistance One of the outstanding properties of semi-crystalline versus amorphous plastics is their resistance to many chemicals, which provides a major benefit in today's healthcare industry where a wide range of substances is used for analysis, cleaning and disinfection, or as a drug carrier or conserving agent.

6 Since factors such as temperature, chemical concentration, exposure time, part surface to weight ratio and the plastic component's stress level can all affect Performance , it is highly recommended that a realistic end-use test be run to determine the suitability of a polymer grade in a particular application (See Figure 4). Barrier Properties Figure 4: Chemical Resistance Hospital Environment The ability of a package to protect its contents (whether in liquid, powder or gel form) against intrusion or loss of Solvents 3. O2, H2O or any other relevant molecule, directly affects the product's shelf life. A common way for packaging products Strong Oxidants 2 Chlorinated Solvents to obtain the right barrier behavior balance is to use a multi-layer structure.

DuPont Performance Materials a broad range of advanced solutions for healthcare components Sterilization Resistance Sterilization is a vital day-to-day procedure in the Healthcare sector, both for single-use and multiple-use devices, so it is important that Materials used in medical components are not affected by this process. The broad range of Materials offered by DuPont Performance Materials provides a suitable solution for nearly every sterilization approach as noted in the table below.
