HCR silicone rubber is a versatile material that is inert, very flexible, and suitable for prosthetic use. HCR silicone rubbers are claylike in the pre-cured state and may be formed into almost any shape without the need to build complex molds. Available as a two-part system, this compound is mixed with the help of a two-roll mill and baked at a low temperature to achieve cured, durable rubber. It is available in several compatible formulations that produce different finished firmness. Add new power to your problem-solving capabilities with these adaptable, elastic, ultra-strong materials making liners, partial feet, and hand and finger appliances. The lecture portion will cover specialized equipment and handling techniques needed for proficiency in fabricating this material. During the hands-on lab, all attendees will make a silicone liner. This CE course is approved for 8 CEU credits by ABC; 9.25 CEU credits by BOC; 6 MCE by OPC.
