Specifications of Silicone
Silicone is a synthetic rubber. It is produced by elements of silisium after several complex reactions. Silicone has some better characteristics than natural rubber so that it is used for modern world requirements where the natural one becomes insufficient.
1- Keeps the physical specifications in high and low temperatures.
2- High resistance for weather conditions, radiation, ultraviolet, ozone, oxygen.
3- Very high electricity insulation.
4- Biological inertia.
5- Does not stick to other materials easily.
Due to its above mentioned specifications it is preferably used in electricals, electronics, general engineering, automotive industry, aircraft industry, vessel industry, illumination, textile, pharmacy, medicine, cosmetics and food industries.
Silicone rubber, practically is good at temperatures between -60 and +180 °C. It works in the a/m temperatures without losing anything of its physical specifications. Even in 250 °C, it works functional for thousands of hours. In extra ordinary cases it can resist to 400 °C or above temperatures for short
periods. It does not burn in high temperatures if there is no flame. If there is a flame, it burns but when the flame is away, burning goes off. Silicone works under low temperatures up to -60 °C and keeps elastic ability. It does not become breakable.
Resistance for Weather Conditions.
Silicone rubber is resistant to ultraviolet, oxygen, ozone and other gases. It does not get pale or cracked even under extreme temperatures. It does not get affected of rain or other liquids. Other rubbers get spoiled quickly in these circumstances.
There is no harmful effect of silicone rubber to human health, because it is an inert material. Therefore it is used in food industry, medicals, pharmacy and cosmetic industry safely. Blood transfusion pipes, oxygen masks, baby pacifiers, stoppers and many such products are made of silicones. Also in food industry, the moulds for cooking of bread and biscuits and carrying bands are made of silicones.
It is very difficult that other materials stick to silicone rubbers.
Resistance for Chemical Effects
Silicone rubber has advantages than other elastomers because they can not be used full functional in high temperatures and under some chemical effects. At some tests, it is observed that silicone has better test results than other materials, keeping its specifications in 25 °C temperature successfully after waiting a week inside some chemical materials.
