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.

During this 8-hour course, the lecture portion of the class will cover special equipment and handling technique needed for proficiency in fabricating with this flexible material, and all attendees will have the opportunity to make a silicone liner during the hands-on lab portion of the course. This CE course is approved for 8 CEU credits ABC; 9.25 CEU credits BOC; 6 MCE credits OPC
