subject: Silicone Rubber Makes Excellent Gaskets And Seals [print this page] Gaskets are used to provide a seal between two surfaces to prevent leakage of fluid or air when the devices are under pressure.
Gaskets are found in systems with fluids under pressure such as vehicles, hoses, air compressors and electrical systems.
If you need rubber gaskets to be used as a seals, it is important to ensure it will do its job for a long. Otherwise, it will lead to all sorts of problems later on.
Effective gaskets in industrial applications must have the ability to withstand high compressive loads.
There are several ways to measure this, the most accepted being the hot compression test. The majority of manufacturers provide tests or publish test results.
Rubber gaskets come in many different shapes and sizes.
Gaskets are usually taken for granted until they stop working, which stops the whole process. Choosing the best, toughest gasket will be the most reliable and have the longest lifespan. Choosing the right material is essential to making sure things keep working correctly.
Silicone rubber gaskets
Silicone gaskets are extremely versatile and are used in a wide range of applications.
Useful properties include temperature, fire and weather resistance, and property seals over many years.
With exceptional high and low temperature and excellent flexibility, silicone rubber gaskets can be manufactured either by moulding it or cutting it from a silicone sheet. The material also has lower moulding pressures compared to other rubber.
However, silicone rubber gaskets material is not always the best material for dynamic applications. It does not do well with oils, for example.
But it does extremely well in static gaskets applications. In gasket applications, silicone can withstand temperatures of between -80o F to +450oF.
Silicone rubber gaskets and seal at Silicone Engineering
You can choose from a huge range of silicone rubber seals, gaskets, washers and sleeves at Silicone Engineering.
The company uses innovative cutting and jointing equipment to produce rubber seals in solid and sponge form, punched or water-jet cut.
There is also a facility for make vulcanised jointed silicone rubber gaskets often incorporating like clips and valves.
These washers are punched from silicone rubber sheeting using a punching machine or made from silicone tubing.
Amazing tolerances are achieved across a range of silicone gaskets.
Silicone rubber (or, to give it its scientific name, Poly-Siloxane) is an amazing material.
It is an inorganic synthetic elastomer, made from a cross-linked silicon-based polymer.
As such, it offers a unique combination of chemical and mechanical properties, which organic elastomers cannot match.
Widely used in a wide variety of industries, it is generally non-reactive, stable, and resistant to extreme environments, stresses and temperatures.
Silicone rubbers mechanical properties include - tensile strength, elongation, tear strength and compression set.
When used in extreme temperatures, these qualities make the material far superior to conventional organic rubbers.
