What are the advantages and disadvantages of silicone rings?
The ubiquitous silicone ring is undoubtedly one of the most used sealing elements that are used today for a good reason. Cheap, efficient and easy to use, Silicone O is a sealing industry with many potential applications. Silicone rubber compounds used in the production of silicone rings give the finished products an impressive number of positive work characteristics such as excellent weather, ozone, acid and thermal resistance. However, the material has several weaknesses, including poor tensile and skid strength and low impermeability characteristics. These negative points are, regardless of the fact that silicone o rings are a suitable choice of sealant of general purpose, if used within their design parameters.
There is a wide range of materials that relate to the production of ong's seals, each lending to the products a specific set of beneficial characteristics. Silicone compounds are one of the materials used to produceRange of the general purpose of rings with good average strengths. Silicone rubber is usually a combination of carbon, hydrogen and oxygen combined with a silicone base polymer. They show excellent resistance to a number of environment elements and are generally unreactive and stable. Silicone rings are also relatively cheap for production, which makes them attractive in terms of costs.
On the other, silicone rings show excellent weathering characteristics with excellent ozone resistance. Heat exposure resistance is also one of the strong points of silicone lead ring seal; Minimum and maximum operating temperatures range between –120 ° F (-84 ° C) and 450 ° F (232 ° C). They are also able to hold their own in an environment that have a chemical exposure, including those that have specific elements of alkalia and acid. The fact that silicone rubber compounds can form formulated to include inerThese fillings that have no negative impact on the performance of the terminal product also allow silicone rings to some of the most effective options available cost -effective.
The disadvantage of silicone ohos, which use centers around their poor general mechanical performance. They do not cut well into shear forces and as such are not suitable for rotary closure applications. In addition, silicone rubber used in the rings do not have high abrasion resistance or tensile strength. Silicone o rings are also unsuitable for applications with exposure to steam or oil and are quite permeable. However, they still provide excellent possibilities of sealing of the general purpose and offer a viable alternative to the more expensive variety PTF, nitril and fluorocarbon.
