What is Silicone Rubber?

Is silicone rubber or plastic? Silicone, scientifically called polysiloxane, hinges on a gray location; however, it’s normally considered a rubber. It’s a human-made elastomer, a polymer with elastic properties, that has the homes of both plastic and rubber. Silicone can be utilized to form liquids, difficult solids, and rubbery items, but considering that elastomers are usually referred to as rubbers, it’s also generally described as a rubber. Silicone is likewise conveniently perplexed with silicon, though they are various materials. Silicon is an element, while silicone is a polymer, a big molecule with repeating devices.

Types of Silicone Rubber

Built on a base of silicon and oxygen, instead of plastic’s base of carbon and hydrogen, which is less secure, teams of organic molecules, including methyl, lend silicone rubber its adaptability. Silicone rubber has a number of variations with attributes that differ depending upon the application for which it’s used.

  • Methyl groups go under the name MQ. These are the fundamental silicone rubbers that were very first established.
  • Methyl plastic groups, which include great compression characteristics, are referred to as VMQ. These are amongst the most generally used types of silicone rubber since the vinyl aids with vulcanization.
  • Methyl phenyl, as well as methyl phenyl plastic groups, are utilized to increase the rubber’s capabilities in reduced temperatures.
  • Flouro, plastic, as well as methyl groups, are more chemically resistant to gas, oil, as well as solvent.

Amongst the family members of silicone rubber variations, there are three primary kinds of silicone rubber, relying on the processing method: fluid, area temperature level vulcanized, as well as heat vulcanized.

  • Liquid silicone rubber has the tiniest molecular chains out of the three types, making its polymers a low molecular weight. It can be extruded or shot formed with specialized equipment. This sort of silicone rubber is more climate-resistant and clear.
  • RTV silicone rubber can be from one or a blend of two components, as well as hardens at space temperature to soft or average hardness. It’s usually made use of for potting, sealant, as well as encapsulations. Silicone rubber molds are likewise made from RTV silicone rubber.
  • Solid or HTV silicone rubber has long-chained polymers with the heaviest molecular weights. This kind usually is available in the unprocessed type, as well as has to be vulcanized at the same temperature level as even more conventional kinds of rubber.
