Polymer Basics for Polycarbonates


Abstract

Polycarbonates are composed of a Bisphenol A part and a carbonate group. They are typically known for their characteristics of toughness, transparency, and having a fairly high heat resistance. Different blends of polycarbonates can enhance desired properties, such as an increase in ductility and impact strength at varying temperatures. They are used in applications such as surgical instruments, connectors, and needle-free injection systems.

Polymer Basics for Polyamides


Abstract

Polyamides are polymers in which the repeating units are held together by amide links. They are more commonly referred to as nylons, and the specific nomenclature for the type of nylon derives from the amount of carbon atoms contained within the molecule. They combine flexibility, hardness, toughness, and resistance to warping all into one material. Polyamides are used in surgical instruments, sutures, and catheters.

Polymer Basics for High Temperature Thermoplastics


Abstract

High temperature thermoplastics are characterized by their high heat resistance (>200 °C), strength, long-term durability, and biocompatibility. In their molecular structure, it is the use of rigid aromatic rings that yields their temperature resistance. These are used in many medical applications including dialysis membranes, surgical forceps, and implantable devices.

Polymer Basics for Fluoropolymers


Abstract

Fluoropolymers are amorphous or semicrystalline fluorine-containing polymers. Due to the very strong, polar bond of carbon and fluorine, fluoropolymers have low surface energy, a low coefficient of friction, and are water repellent. In addition, these materials have a high chemical resistance, have excellent dielectric properties, and are biocompatible. They are used in medical applications ranging from flexible tubing to catheters.

Polymer Basics for Elastomers


Abstract

A silicone polymer has a chemical composition that is made up of silicone, hydrogen, and oxygen. A silicone elastomer has somewhere between 3,000-10,000 repeating units. The silicone elastomers have a high polymer chain flexibility, are chemically inert, and are biocompatible. They are used in medical device applications ranging from artificial ears to tubing and implants.

Thermoplastic elastomers are low modulus, flexible materials that can be stretched to twice or more their original length. The properties and characteristics are those between rubbers and plastics. They are used in applications such as eye drop bottles, disposable gloves, heat shrink tubing, and surgical films.
