MEDICAL POLYMERS PROCESSING SELECTING RIGHT MATERIALS & MANUFACTURING SYSTEMS

 

Applications in the healthcare industry and medical devices in particular, have some demanding requirements for polymeric materials. While polymers have been used in the healthcare industry for decades, it has only been in the recent past the designers have started to explore the benefits of using special materials in the medical applications.

 

Materials selected for use in new medical devices can have major ramifications throughout the product lifecycle, from design through testing, during regulatory approvals and production, and in the build up to market adoption and even disposal.

 

There are many considerations to keep in mind while choosing a polymer for Medical Device viz Environment during transportation and product use, Chemical Resistance, Durability, Biocompatibility, Appearance, Feel, Sterilization, Molding, Price, Weight, Recyclability etc. Discussions analyzing two important aspects follows. The first is related to selecting a polymer in direct contact with the flow of drugs through a device. It is required to look at the effect the material has on drugs. Chemical resistance is also important, as the drugs should not promote the materials degradation. Also the potency of the drug should not be affected by the polymeric material it is in contact with either via extraction of additives and monomers, or via the chemical reactivity between the drug and the polymer.

 

One more important aspect is regarding molding. It is possible to make extremely precise design tolerances. Complex, intricate features can be effortlessly included with the help of rightly designed moulds.
