Frequently Asked Questions
What is a Silicone Rubber Sheet?
Silicone Rubber Sheet is a type of rubber sheet made from silicone, which is a synthetic polymer that has excellent resistance to high and low temperatures, chemicals, weathering, and UV radiation. Silicone rubber sheets are highly durable and flexible, making them ideal for a wide range of applications in various industries.
Silicone rubber sheets are available in different thicknesses, sizes, and colors, and they can be customized to meet specific requirements. They are commonly used for gaskets, seals, insulation, vibration dampening, and other industrial applications where resistance to high or low temperatures and chemicals is required. Silicone rubber sheets are also used in the food and medical industries because they are non-toxic and odorless.
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.
What are the benefits of using silicone rubber sheets?
Silicone rubber sheets have several advantages, including excellent temperature resistance, chemical resistance, and durability. They are also flexible, easy to fabricate, and can maintain their physical properties over a wide temperature range.
What are the temperature limits of silicone rubber sheets?
Silicone rubber sheets can typically withstand temperatures ranging from -60°C to 200°C (-76°F to 392°F), with some high-performance grades capable of withstanding even higher temperatures.
Are silicone rubber sheets FDA compliant?
Yes, silicone rubber sheets can be FDA compliant if they meet certain criteria. Silicone rubber sheets used in food processing or medical applications must meet specific requirements for purity, biocompatibility, and toxicity. Manufacturers can provide certification for FDA compliance if requested.
