Liquid Silicone Rubber vs Solid Silicone Rubber

Table of Contents

Silicone rubber is a synthetic polymer resin made by polymerizing silica, carbon, hydrogen, oxygen, and other organic compounds.

Silicone rubber is used in the manufacturing of silicone products. It is the most widely used material in the field of pharmaceuticals. Silicone rubber has also found its use in many other industries like aerospace industry, automotive industry, construction industry etc.

Silicone rubbers are often classified based on their performance capability into high performance rubbers and low performance rubbers.

What are the Different Types of Silicon Rubbers?

What are the Different Types of Silicon Rubbers?

Silicon is an important chemical that forms a liquid at room temperature. Silicon rubber has many uses, ranging from the medical to the automotive industry.

Silicone rubbers are divided into two types, liquid and solid.

  • Liquid silicone rubber: is a liquid that has been polymerized, or solidified, into a rubber-like substance. It is used in the production of various polymeric products, such as gaskets and seals, and in the manufacturing of plastics. The liquid silicone rubber types are further divided into three categories:

    1) Silicone oil

    2) Silicone grease

    3) Silicone fluid

  • Solid silicone rubber: come in various grades and compounds, which determines their properties like flexibility and abrasion resistance. Solid silicon rubbers can be used for thick applications like car body panels and the engine block.

What Are the Properties of Silicone Rubbers?

Silicone rubbers are widely used in molding, rubber processing, and chemical industries.

Silicone rubbers are used in all types of products. The major property of silicone rubbers is their ability to retain heat. This is due to the presence of silicon dioxide in the compound. Silicone rubbers are also easy to process with other additives and often have high compressive strength. Let’s go through more properties of silicone rubber and how they affect us:

Why Use Silicone Rubbers?

  • 1) Silicone rubbers can be vulcanized into materials that provide excellent wear and low friction coefficient
  • 2) Silicone rubbers have good electrical insulating properties
  • 3) Silicon rubber has low toxicity and high resistance to chemicals
  • 4) It’s durable, elastic, and tough
  • 5) It’s an anti-reflective material
  • 6) It’s high temperature resistance
  • 7) It’s high compressive strength

Excellent Flexibility

  • Solid Silicone rubber has excellent flexibility, it can be modified easily and responds well to a variety of circumstances.

Noise Reduction

  • Solid silicone reduces high volume noises passing through.

Vibration Dampening

  • The rubber reduces vibration, suitable for mass transit applications.

Sealing

  • Solid profiles are mainly used for precision sealing, this format of silicone responds well to sealing tight spaces due to its flexible nature.

Insulation

  • Solid silicone rubber is designed to stop the process of heat and electricity from spreading.

Thermal Insulation

  • The silicone material stops unwanted heat from entering through to the other side.

Thermal Shielding

  • The silicone material acts as a shield from absorbing excessive heat from travelling to it’s centre.

Gasketing

  • Solid silicone gaskets sit between two surfaces, generally to prevent leakage into the joined objects while under compression.

Silicone rubbers are typically found in automotive and consumer goods products. They are often used as anti-vibration, cushioning, and vibration dampening materials. This type of material is used in many industries such as transportation, medical devices, and aerospace.

Solid Silicone is a solid type of silicone rubber that has been modified by adding foreign material, such as silica or carbon black, during production. The foreign material can be added to create a variety of textures and colors to the finished product. Silicone rubbers also have low elasticity which makes them rigid at room temperature but pliable when warmed up or cooled down. This makes silicone rubbers well-suited for applications where they need to maintain.

Silicone is both a solid and liquid. It is the second most used polymer in the world after polyethylene terephthalate. Silicone can be manufactured into thin sheets, tubes, rods, balls, slabs, or wires that are flexible but tough.

Silicone is often mistaken for being a liquid because of its ability to flow easily at low temperatures. The truth is, silicone has a different molecular structure than water so it becomes viscous when heated up.

Silicone solids can be made to have a variety of mechanical properties by altering their molecular structure with additives like metals or metal oxides.

Silicone rubber is a strong, durable material that is usually used to make appliances and other devices.

  • – It’s durable – Silicone rubber is mostly non-porous and therefore will not absorb water or liquids like most other plastics can; it won’t degrade quickly like vinyl which tends to wear out over time.
  • – It’s lightweight but still has enough strength to make sure that it lasts for years – Silicone rubbers are known for their durability and flexibility which makes them perfect for appliance parts like knobs, handles, etc…
  • – It can be recycled easily

Silicone is a polymer. It is a natural organic compound that is made from silica, carbon, hydrogen, and oxygen.

Plastic is a term for a man-made polymer that contains oil and other synthetic substances. The term was first coined in 1839 by Scottish chemist Joseph Gay-Lussac.

Silicone is completely toxic free, and more eco-friendly than plastic. It lasts longer, and stands up better against heat and cold than plastics. Silicone has an elastic quality while plastic does not. Silicone can be stretched to 5 times its original length without breaking whereas plastic can only be stretched to 1 time its original length before it breaks or shatters.
