What Is The Difference Between Silicone And Silicone Gel?

Although silicone and silicone gel have similar names, they differ significantly in material properties and applications. Here are the main differences between silicone and silicone gel:

Silicone: Silicone typically refers to a solid siloxane material. It can form elastomers or hard materials after heating or curing and is widely used in seals, gaskets, pipes, and kitchen utensils.

Silicone Gel: Silicone gel is a soft, semi-fluid, or gel-like material. It remains semi-solid at room temperature, exhibiting good fluidity and softness. It is often used in applications requiring filling, cushioning, or sealing, such as medical patches, shock-absorbing materials, and protective films.

Production Process

Silicone: The production process for silicone generally involves curing the liquid silicone precursor at high temperatures to form a solid, elastic material.

Silicone Gel: The production process for silicone gel involves the gelation of the silicone precursor, resulting in a gel-like consistency.

Application Fields

Silicone: Due to its strength and durability, silicone is commonly used in applications requiring mechanical strength and high-temperature resistance.

Silicone Gel: Owing to its softness and cushioning properties, silicone gel is primarily used in applications requiring protection and filling, such as in medical devices, shock-absorbing pads, and electronic product protective films.

Performance Characteristics

Silicone: Silicone is known for its high temperature resistance, chemical resistance, and excellent elasticity. It remains stable across a wide temperature range and resists corrosion from various chemicals.

Silicone Gel: Silicone gel is used in products needing protection and comfort, such as filling pads and medical supplies, providing excellent cushioning and softness.

Mechanical Strength

Silicone: Silicone generally has high mechanical strength and wear resistance, making it suitable for environments that endure physical pressure and impact.

Silicone Gel: Silicone gel has lower mechanical strength and primarily relies on its softness and cushioning properties to protect other materials or surfaces. It is ideal for applications where high strength is not required but softness and comfort are essential.
