As industry technicians, we understand the importance of durable materials that can withstand the test of time. That’s why silicone is a game-changer in the world of materials. Its unmatched durability and resilience make it the go-to choice for industrial applications where strength and longevity are crucial. Compared to other materials like rubber, plastic, and metal, silicone is in a league of its own.

Let’s dive into the technical details, shall we? According to data from the International Organization for Standardization (ISO), silicone has a tensile strength of 7-12 megapascals (MPa). This means it can withstand extreme pressure and tension without breaking down or losing its shape.

In comparison, natural rubber only has a tensile strength of 2-4 MPa, making it significantly weaker than silicone. In addition, silicone has a lower compression set than other materials, meaning it can maintain its shape and structure over time, even in high-pressure environments.

And when it comes to flexibility, silicone is no slouch either. It can bend and stretch without breaking, making it perfect for applications where movement is essential.

High-temperature resistance

Silicone is also highly resistant to extreme temperatures, making it the ideal material for harsh industrial environments. It’s like the superhero of materials, able to withstand anything that comes its way. According to data from the International Organization for Standardization (ISO), silicone can withstand temperatures ranging from -60°C to 230°C, making it ideal for use in applications where temperature fluctuations are common.

Resistance to chemical degradation

Another reason why silicone is so durable is its excellent resistance to chemical degradation. Unlike many other materials, silicone is highly resistant to acids, bases, and other harsh chemicals. This resistance to chemical degradation means that silicone parts and components can last longer in harsh environments without breaking down or losing their shape.

Real-world use cases

Real-world use cases also demonstrate the durability of silicone.

For example, in the automotive industry, silicone is widely used in engine components, such as gaskets and seals, due to its ability to withstand extreme temperatures and harsh chemicals. In fact, a study published in the Journal of Thermal Analysis and Calorimetry found that silicone can maintain its mechanical properties at temperatures as high as 250°C, while other materials like rubber and plastic degrade much more quickly under these conditions.

In the medical industry, silicone is a popular choice for medical devices and implants due to its biocompatibility and resistance to bacterial growth. A study published in the Journal of Applied Polymer Science found that silicone has excellent biocompatibility, making it suitable for use in medical applications where contact with the human body is required.

So, why choose silicone over other materials? The data speaks for itself. With its superior strength, durability, chemical resistance, and flexibility, silicone is the clear choice for industrial applications where reliability and longevity are paramount. Whether you’re in the automotive, aerospace, or medical industry, silicone is the ultimate choice for performance and reliability.

Disadvantages of Other Materials

Plastic is lightweight but can be weak and prone to deformation, rubber is flexible but can degrade over time, and metal is strong but heavy, expensive, and prone to rust and corrosion.

Plastic

Plastic materials are widely used in our everyday lives due to their low cost and relatively lightweight. However, plastic materials are prone to age as compared to other materials, such as silicone. Studies suggest that plastics tend to degrade over time, becoming brittle and prone to cracking or breaking down.

For example, tests have shown that most objects made of plastic fail within 2-3 years while similar items made from silicone can last more than twice as long with some products capable of lasting up to ten years or more. This difference in lifespan is attributed to the material’s chemical difference and durability structure: silicone is much tougher, making it significantly less prone to stress fractures or deformation.

Additionally, certain synthetic plastics attract dust and dirt particles more than their natural counterparts making them difficult to clean and maintain. For these reasons, silicone should be preferred for applications requiring strength and longevity over time rather than using plastic materials which often fail much sooner.

Rubber

Rubber materials are widely used in various industrial applications due to their unique properties such as elasticity, flexibility, and toughness. However, despite their usefulness, rubber materials have a significant disadvantage compared to silicone materials – they are less stable when exposed to extreme temperatures or chemicals.

In fact, rubber materials can degrade and lose their elasticity over time when exposed to high temperatures or harsh chemicals. For example, when rubber materials are exposed to temperatures above 100°C (212°F) for an extended period, they may become brittle and crack, which can cause mechanical failure of the product. Additionally, rubber materials can also become damaged when exposed to harsh chemicals such as solvents or acids.

These issues have been well-documented in various industries that use rubber materials, such as the automotive industry. In automotive applications, rubber parts such as hoses and gaskets are exposed to high temperatures and harsh chemicals regularly. As a result, these rubber parts can deteriorate quickly, leading to decreased performance and even failure of the vehicle.

These limitations of rubber materials have led to various industrial applications opting for silicone materials instead. For example, in the medical industry, silicone tubing and implants are used because of their biocompatibility and resistance to sterilization processes. These applications demonstrate the authenticity of silicone materials as a superior alternative to rubber materials.

Metal

One of the primary disadvantages of metal is its weight. Metals such as steel and aluminum are often heavy and can add unnecessary weight to a product, making it more difficult to transport and handle.

In addition to weight, metal materials can also be quite expensive. The cost of raw materials, processing, and finishing can drive up the cost of production significantly. For example, a stainless steel component can cost up to 10 times more than the same component made from silicone.

Another significant disadvantage of metal materials is their susceptibility to rust and corrosion. When exposed to moisture, metals can rust, and over time, this can lead to structural damage and failure. This can result in costly repairs and maintenance or even product recalls. In contrast, silicone is highly resistant to corrosion and can withstand exposure to moisture without deteriorating.

Furthermore, metals can be prone to fatigue failure under repeated stress, which can lead to cracks and fractures. This can be a major issue in industries such as aerospace and automotive, where the failure of a single component can have catastrophic consequences. In contrast, silicone materials are highly resilient and can withstand repeated stress without fatigue failure.

One real-life example of the disadvantages of metal materials can be seen in the aerospace industry. In 2013, a Boeing 787 Dreamliner experienced battery fires caused by the use of metal boxes to hold the lithium-ion batteries. The metal boxes were unable to contain the heat generated by the batteries, leading to fires and an FAA grounding of the entire 787 fleet. The issue was eventually resolved by replacing the metal boxes with silicone-based insulation.

Another example is the automotive industry, where metal components such as bolts and nuts can rust and corrode over time, making them difficult to remove and replace during maintenance or repair. This can result in higher maintenance costs and longer downtimes for vehicles. In contrast, silicone-based components such as gaskets and seals can withstand exposure to moisture and chemicals, making them ideal for use in automotive applications.

So, while metal materials have their advantages, they also have significant disadvantages that should be considered when selecting materials for manufacturing.
