Silicone material has been widely used in various industries in recent years, and products made of silicone material can be seen in food hygiene, industrial equipment, etc. For example, silicone sealing rings. So what are the differences between silicone sealing rings and sealing rings made of other materials?1、 Excellent weather resistanceWeathering resistance refers to a series of aging phenomena that occur due to external conditions such as direct sunlight, temperature changes, wind and rain, such as fading, discoloration, cracking, pulverization, and decreased strength. Ultraviolet radiation is the main factor that promotes product aging. The Si-O-Si bond in silicone rubber is highly stable to oxygen, ozone, and ultraviolet radiation, and has excellent resistance to the erosion of ozone and oxides. Without any additives, it has excellent weather resistance and does not crack even when used outdoors for a long time. It is generally believed that silicone rubber sealing rings can be used outdoors for more than 20 years.2、 Material safety and environmental protectionSilicone rubber has its unique physiological inertness, is non-toxic, odorless, odorless, and has a good preservation effect. It is also less affected by external environmental interference and does not turn yellow or fade after long-term use. And it complies with national food and medical hygiene standards, and is mainly used for filtering impurities in food, medicine, aluminum silver paste, and various oils.3、 Good electrical insulation performanceOrganic silicone has excellent electrical insulation properties, as well as excellent corona resistance (ability to resist quality degradation) and arc resistance (ability to resist deterioration caused by high-voltage arc action).4、 High breathability and selectivity for gas permeationDue to the molecular structure of silicone, the silicone sealing ring has good breathability and gas selectivity. At room temperature, the breathability of silicone rubber to gases such as air, nitrogen, oxygen, and carbon dioxide is 30-50 times higher than that of natural rubber.5、 Has moisture absorption performanceThe surface energy of silicone rings is relatively low, and they have the ability to absorb moisture in the environment and act as a barrier.
