Customized Silicone Compounds
For your Specialized Needs

CRI-SIL Silicone Technologies, LLC was founded in 1994 to fill a need for specialized custom silicone materials. The goal was to move away from big business bureaucracy while retaining big business technology and favorable pricing.
Over the years we have maintained that mentality, and as a result, have proven that we can partner with our customers to develop some of the best materials in the industry. If you do not see a product you need listed on this website, please call or email us.



CRI-SIL Silicone Technologies, LLC is an ISO9001 certified supplier of custom formulated silicone and fluorosilicone elastomers. We provide products and solutions to customers worldwide that are seeking innovative silicone rubber compound engineering.

We offer a full complement of standard silicone products and services in addition to custom formulations. Fabricators in the Wire and Cable, Automotive, Healthcare, and Aerospace markets (to name a few) can choose a product right off the shelf or submit a specification for custom engineering. For those Fabricators seeking Liquid Room Temperature Vulcanization (RTV), or Heat Cured Rubber (HCR), we will develop and deliver a high-quality product to you in minimal time and tailor made to your price and specification requirements.


For fabricators who also mix their own material, we offer a full line of silicone bases in a complete durometer range for your own custom formulations. Simply add your own color and catalyst! All materials are available in lot sizes from 5 lbs. to 1000 lbs. and in almost any preform. If you have any questions, please contact us.
