For silicone elastomers to have strong mechanical characteristics, reactive, cross-linking agents, straight-chained molecules, and reinforcement are combined. The global silicone elastomers market is projected to reach hit $16,425.2 million by 2030.
This is brought on by the strong need for silicone elastomers in the electronics sector, their excellent qualities, and an aging population, driving product demand in the healthcare sector. The three primary types of silicone rubber are as follows:
• High-Temperature Vulcanized (HTV) – Relatively long polymer and high molecular weight chained materials make up solid silicone rubber. They can be found uncured and need conventional rubber processing methods.
• Liquid Silicone Rubber (LSR) – The polymers in liquid silicone rubber have shorter chains and lower molecular weights. It has improved flow characteristics. It is processed using equipment for extrusion and injection molding that is specifically developed.
• Room Temperature Vulcanized (RTV) – RTV silicone elastomer has a hardness range of extremely soft to medium and is created from one-part (RTV-1) or two-component (RTV-2) systems. They can be used for sealants, encapsulations, potting, etc.
The Benefit of Silicone Elastomers
Quality: High-performance applications requiring extreme purity are ideal for silicone elastomers. They adjust to various manufacturing issues in many sectors, including the production of home goods, automobiles, electronics, and molds. The variety of possible specialized uses for silicone elastomers may be further expanded by converting them to food-grade compliance.
Versatility: You may easily and cheaply tailor silicone elastomers to meet performance and changing procedural requirements. Because of this, innovative businesses promoting manufacturing and testing innovation embrace silicone elastomers.
Performance: The ability to withstand both cold and hot temperatures is one of the unique characteristics of silicone elastomers, allowing them to retain a low-pressure set-in condition of severe heat while staying flexible in conditions as low as -40 °C.
In addition, silicone elastomers have high dielectric strength, low flammability, durability, sterilizability, and generally strong mechanical characteristics that might benefit any application.

Potential User of Silicone Elastomers
The automotive industry, which creates around 90 million cars annually, is constantly developing and requiring new high-performance materials for the engine and other car sections. A high air pressure, increased water flow, more potent fuel injection, and corrosive fluids need sophisticated automobile parts’ design.
Additionally, automakers must lower the weight and fuel usage of their vehicles, which leads to smaller, more streamlined engine chambers. The smaller area causes higher heat and increased stress on the important parts.
These extreme temperatures and conditions are too severe for conventional materials to sustain. HTV and LSR silicone elastomers can withstand temperatures of more than 250 ◦C because of their repeating siloxane groups with methyl groups, each attached to the silicon atom. As a result, they are suitable for a variety of vital parts.
Modern silicones are created with compression at high temperatures for automotive applications. Additionally, safe for human use and resistant to the high temperatures needed for sterilizing, silicone elastomers are perfect for medical applications.
Conclusion:
To sum up, the application and the task you require the elastomer to do heavily influence the choice of elastomer or rubber. However, as previously said, silicone will most certainly fail if it comes into touch with oil or petroleum.
