Silicone Sheet

Silicone Rubber Sheets: Silicone is a synthetic rubber used to make gaskets. Silicone can withstand 200°C, and is chemically inert, which makes it superior in the food processing industry.

Silicone Rubber Properties

Silicone rubber’s strongest mechanical properties are its temperature resistance and flexibility. This material can handle temperatures between -150 degrees and 550 degrees F before turning brittle or melting, depending on the variant. Its tensile strength is between 200 and 1500 PSI, and its maximum elongation is 700%, which is exceptionally good for rubber.

On top of that, it rebounds and compresses fairly well, is heat and flame resistant as well as an electrical insulator, and bonds well with metals. Silicone rubber works well in outdoor conditions, thanks to its UV, ozone, and general weather resistance.

It’s also hypoallergenic and water resistant while staying permeable to gases, which makes it popular in medical applications. Since it’s more chemically inert than most plastics, nonstick, and doesn’t stain, it can be found in consumer as well as industrial food and beverage applications. In its sponge form, silicone rubber is lightweight while reducing vibration and noise, so it’s also used in transportation.

However, this material also has some drawbacks. Silicone rubber is not oil resistant for long periods of time, and it can swell after long periods of contact with oil or petroleum, although there are more oil resistant varieties. It’s also not abrasion or tear resistant, and it can get stiffer at higher temperatures.

Mostly, though, because of its special properties silicone rubber is one of the more expensive types of rubber, and it’s usually replaced by something cheaper when large amounts are needed.
