Silicon rubber is the name we give silicon products because of its rubber like structure. Silicon rubber contains, in addition to silicon, oxygen, hydrogen and carbon. Silicon itself is a polymer, which makes the silicon rubber largely polymer in nature. Silicon rubber profile India may also contain fillers to make it more cost-effective or to enhance a certain property.
Silicon rubber is a very high performing class of polymers, which is used in many critical applications across various industries. Silicon rubber has qualities that make it suitable for very demanding applications. At the same time, silicon is easy to produce and cost-effective. Hence, its usage has been steadily increasing it first appeared as a commercial product for manufacturing. Silicon rubber has certain properties that put it far above organic or other type of rubbers.
Resistance to high or low temperatures
Silicon rubber has one of the best resistivity to temperature extremes. Studies have shown that it can withstand temperatures as high as 350ºC for short periods, 200ºC for around 10,000 hours and 150ºC indefinitely. On the other end of the spectrum, it can comfortably withstand temperatures of -60ºC — -70ºC with some products able to bear temperatures as low as -100ºC.
This resistance to extreme heat and cold is one of the reasons for the popularity of silicon rubber profiles India in the manufacturing sector. Unlike other rubbers, it does not become brittle in extreme temperature and retains it elasticity. As a result, it is used in high heat applications like automobile engines or very cold environment such as in aerospace.
Weather ability or the ability to weather environmental changes is very high in silicon, much better than ordinary rubber. It can be exposed to wind, rain, UV rays and sun for prolonged periods without any deterioration. It is also very good at withstanding ozone degradation which has very little effect on its integrity. This makes it useful for a number of outdoor applications, including wearables.
Steam and moisture resistance
You can submerge silicon rubber in freezing, boiling or normal water fro a prolonged period and see virtually no change in its physical properties. This is why many underwater installations use silicon rubber for critical applications like sealing. Even more important is the response of silicon rubber profile India to steam. Where other rubber will deteriorate in the presence of steam, silicon rubber shows no change. However, it should be noted that it does react to pressurized steam when the pressure keeps increasing. This property is one of the reasons silicon is so popular as wearables in high moisture conditions.
Silicon rubber is one of the most effective component when it comes to insulating materials. Its insulating properties remain constant in different environments, temperatures and frequency, making it uniquely suitable for electronic insulation. It can withstand corona discharge and will be effective as insulating material even when immersed in water. Silicon rubber is today the preferred material when working with high voltage.
Chemical, Oil And Solvent Resistance
Like a lot of rubbers, silicon rubber also has high resistance to oils, chemicals and solvents. While silicon rubber’s resistance to oils may not be as good as certain other organic rubbers, its performance under high temperature puts it ahead of others. It is largely unaffected by most chemicals and solvents, including polar organic compounds and dilute acids and bases. Even in non-polar organic compounds, silicon will not easily decompose. Some solvents can soften the material. Strong acids and bases will also adversely affect silicon. But on the whole, silicon has a far better resistivity than other rubbers.
Like other rubbers, silicon rubber profile India is not resistant to fire, but when treated with a flame retardant, it shows better performance. It produces no noxious gas or black smoke when burnt. This makes it a preferred component from the environmental viewpoint. Since it does not create any harmful effects on burning, it is used in closed spaces and consumer electronics.
The compression set of Silicon rubber profile India stays consistent even under different temperatures, with a better performance than other rubbers. This is why silicon rubber is used in gaskets where the ability of the rubber to recover from compression’s is crucial. Along with its ability to adhere and release easily, silicon rubber makes a great sealer.
