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.
