The Importance of Silicone Rubber Buttons in Electronics Design Brisbane

Silicone is made of an artificially produced polymers that are made of hydrogen, silicon, oxygen, and carbon. Its generic formula: [R2SiO]. Considering the type of the silicone, R could be either methyl or phenyl or ethyl group of organic molecules. On the other hand, [SiO] is a strain of organic oxygen molecules and silicon that are chemically bonded. Silicone has always played an important part in electronics design Brisbane.

Silicones that are used in the production of silicone keypads come with a wide array of exceptional qualities. Some of these qualities include the ones below.

  • Non-toxic
  • Eco-friendly
  • Non-corrosive
  • Chemical inertness
  • Non-sticky
  • Waterproof
  • Resistance to harmful bacteria
  • Ability to serve as an electrical insulator
  • Resistance to oxygen, ozone and ultraviolet light
  • Thermal stability under the temperatures ranging from -1000C to 2500C

Silicone Buttons and their Advantages

These buttons are widely used in a variety of products and electronics design Brisbane like calculators, medical devices, industrial keypads, remote controls, PLCs, as well as in building construction equipment.

Generally, silicone keypads along with a carbon contact pill are needed to activate or deactivate the electric circuits. As soon as the rubber keypad is being pressed, the position changes so the carbon contact pill will complete the electric circuit, thus allowing the flow of current. As compared to other means of circuit activation, such is considered to be the most reliable and effective as it does not need mechanical switches that are known to have higher production cost and shorter lifespan.

There are some types of electric machine that operate below the freezing point. These buttons are utilized to activate and they are made of silicone rubber as such material is capable of withstanding low temperatures.

In addition, it is also resistant to UV light, the rubber buttons will be used in ultraviolet light medical apparatus. Moreover, it is a non-sticky kind of material and this makes the buttons pleasant and convenient to use.

 

Customization

These processes are used in manufacturing silicone rubber products.

  •         Vulcanization (compression molding)
  •         Injection Molding

In the vulcanization process, the silicone gets into chemical reactions with peroxidesor urethane cross linkers or sulfurs or deuces or metallic oxides or acetoxysilanes. The main goal of this process is to force the silicone rubber to take the shape of the mold.

At the start of the injection molding process, the silicone matter will be placed into a barrel that is heated above the melting temperature of the silicone. Then, a high apparatus pressure will be used to pour the melted silicone into the cold mold. The liquid silicone will then take the shape of the mold and will eventually harden while the temperature drops to room level.

Knowing all these things is necessary so you can better maximize your electronics design and how silicone rubber creates a great impact in the said design.
