Course: Essentials of Silicone Rubber

July 12 @ 1:00 pm - 5:00 pm


0.4 (To receive the CEUs, attendees must attend the course live and promptly complete the survey evaluation after the course.)
July 12, 2023; 1 p.m. – 5 p.m. ET


This course is only available virtually. It can be taken from the comfort of your home or office – remotely from any tablet, laptop or computer.

Course Overview:

Silicone rubber is comprised of inorganic-organic polymers. These materials consist of an inorganic backbone with organic side groups attached to silicon atoms. This family of polymers possesses unmatched versatility giving the formulator and user multiple forms and methods to cross link the polymers into rubber materials having the widest service temperature range of any rubber material. This course is designed to provide participants with a thorough understanding of silicone’s engineering characteristics. It will take you from creation of silicone from sand through formulating the compound and the various methods by which silicone can be fabricated into useful service articles. The subject matter will deal with the differences between high consistency rubber, caulks and the various liquid silicone rubbers. This course is suitable for those individuals having various degrees of knowledge in silicone materials and applications.

Learning Objectives:

  • contrast the differences between silicone rubber and other rubber materials
  • discuss the influences of specific silicone polymer architecture on engineering properties
  • choose the corrective additives to influence specific performance attributes
  • recognize the differences between the different types of silicone rubbers
  • contrast the different silicone rubber curing and fabrication systems
  • discuss the engineering characteristics the make silicone rubber unique
  • recognize when to use silicone rubber in an application
  • apply the principles presented in this course to improve the quality of silicone rubber articles

Topical Outline:

  • what silicones are
  • how are they made
  • differences between silicone rubber and other rubber materials
  • what makes silicone rubber unique and when to use it instead of other rubber materials
  • influence of additives to during construction of the silicone rubber compound
  • essential differences between high consistency and low viscosity and liquid molding
  • types and influence of different cure systems
  • manufacturing of silicone rubber compounds
  • fabrication technologies
  • troubleshooting
