SILICONE SOURCE-CERTAIN HEXSEAL® Switch & Circuit Breaker Seals SM MAKING SILICONE SENSE

SILICONE INTEGRITY Hardly a day goes by when the media isn’t reporting on the lack of integrity in politics. In commerce, counterfeit electronic components are finding their way into U.S. military equipment. And in medicine, counterfeit breast implants utilizing industrialgrade silicone instead of the appropriate medicalgrade are forcing their replacement in a significant number of women. This is unacceptable. At APM, we feel that silicone integrity is essential to producing switch and circuit breaker seals that will perform to the highest standards, as promised. That’s why we are proud to...

APM WAS THERE AT THE BEGINNING OF THE SILICONE SEALING REVOLUTION AND CONTINUES TO LEAD such as fluoro-silicones, Viton®, Buna N, ethylene Jacob Berzelius discovered silicone Si in 1824 from a hard form of silicon oxide called silica. After oxygen, and hydrogenated nitrile were added to the list as an silicon is the most common chemical element on alternative for other chemical and solvent exposures. earth; found in rocks and sand. It wasn’t until 1943, as This joint effort resulted in a new governing part of the war effort, that chemists at Corning Glass specification being...

BEWARE OF SILICONE SEALS MADE WITH FILLERS AND RE-CYCLED SILICONE RUBBER Our basic building block is high-grade quartz to which catalysts, color pigments and ultra violet resistant chemicals are added and blended. All conform to the rigorous specifications of A-A-59588, Class3B, GR 50 (unless otherwise specified). We never add fillers or re-cycled silicone rubber to our processing formula — an undesirable practice employed by some competitors. APM uses ONLY 100% pure silicone rubber with careful sourcing control. With more than sixty years of experience in mold design, APM produces...

SILICONE IS IN OUR DNA Care and experience are paramount when designing sealing systems that are subject to frequent and aggressive usage. Characteristics such as tensile strength, fatigue and loading are considered. Polysiloxanes, consisting of Si-O-Si units, are very flexible because of their large bond angles and lengths — they can move further and change conformation easily compared to other polymers that contain carbon backbones. Polysiloxanes tend to be chemically inert, due to the strength of the siliconeoxygen bond. For more than 60 years APM has excelled in silicone rubber...
