How does the "wide temperature range warrior" characteristic of silica gel come about?
Have you ever wondered why silica gel can withstand the extreme cold of icy weather and also brave the high temperatures of ovens? The secret lies in its unique molecular structure.
Unlike the carbon-carbon main chain of ordinary rubber, the main chain of silicone is composed of alternating connections of silicon atoms and oxygen atoms (silicon-oxygen bonds). This chemical bond has a higher bond energy and a greater rotational freedom of the molecular chain, making it less likely to break at high temperatures and less likely to be "frozen" and become brittle at low temperatures.
This gives silicone an astonishing stable working range of -60°C to 200°C. Whether it is the extreme environment sealing in aerospace or the daily preservation of household bread boxes, silicone can handle them with ease, providing you with reliable protection across the spectrum of cold and heat.
