Silicone Rubbers Vs. Other Materials
Let’s delve into how silicone rubber stacks up against other materials, notably EPDM Rubber and Rigid Rubber material, and understand why businesses often opt for silicone.
EPDM (Ethylene Propylene Diene Monomer) rubber is a versatile material known for its outstanding heat, ozone, and weather resistance. However, silicone rubber stands out regarding overall temperature resilience and flexibility. It can operate in more extreme temperature conditions, both hot and cold, making it a go-to choice for businesses in sectors like aerospace, automotive, and medical devices, where such resilience is paramount.
Rigid Rubber Material
More rigid rubber material, including hard rubber, have their place in the industry due to their firmness and durability. Yet, they often lack the elasticity and pliability that silicone rubber offers. Silicone’s flexibility means it can stretch and bend without damage, making it ideal for applications such as seals, gaskets, and various medical devices.
Natural rubber offers excellent tensile strength and elasticity. However, it doesn’t stand up to temperature extremes or UV exposure as well as silicone rubber does. Silicone rubber’s superior temperature and weather resistance make it the preferred choice for outdoor applications or those requiring exposure to high heat.
Nitrile rubber is known for its resistance to oils and chemicals. Despite this, it falls short in terms of temperature resistance compared to silicone rubber. Silicone’s ability to withstand extreme temperatures without degrading allows it to maintain its integrity in high-temperature environments, like engine parts or cooking utensils.
Polyurethane rubber boasts impressive abrasion resistance, making it perfect for applications like wheels and casters. However, it lacks the flexibility and temperature resistance of silicone rubber. This limitation can be a disadvantage in applications that require a material to maintain its properties under a wide range of temperatures.
Causes of Silicone Rubber Degradation
Although silicone rubber boasts impressive resilience, it’s not immune to degradation. Several factors can contribute to the deterioration of silicone rubber. By understanding these, businesses can better implement preventive measures, thus extending the product’s lifespan.
Elevated Temperature Issues
One of the culprits causing silicone rubber degradation is excessive heat. While silicone rubber performs exceptionally well at high temperatures, prolonged exposure can still have negative effects.
· Thermal Expansion
Silicone rubber expands when heated. This thermal expansion can lead to stress and eventual degradation if the material is confined or bonded to a rigid structure. For instance, a silicone rubber gasket exposed to repeated heat cycles in the automotive industry can begin to degrade if not designed to accommodate expansion.
· Changes In Chemical Composition
Prolonged exposure to high temperatures can also change the silicone rubber’s chemical composition. This alteration might reduce the material’s elasticity and resistance to tear, affecting its performance over time. A real-life example can be seen in the kitchen, where silicone rubber spatulas exposed to extreme heat over long periods may start to stiffen or crack.
Mechanical Stress Factors
Silicone rubber is also subject to mechanical stress factors. These include constant pressure or repetitive flexing, which may cause the material to wear down over time. For example, in the medical industry, silicone rubber tubing used for fluid transfer may degrade over time due to the constant pressure of the fluids passing through them.
Gas Diffusion Layer And Porosity
The presence of gas diffusion layers and porosity can also accelerate the degradation of silicone rubber. This is particularly relevant in industries like the fuel cell sector, where silicone rubber components are exposed to gases. The diffusion of these gases into the silicone material can lead to swelling and, eventually, degradation.
How to Prevent Degradation, Leakage, And Failure
Understanding the root causes of silicone rubber degradation helps devise strategies to counter these issues. Let’s delve into a few strategies that can enhance the performance and longevity of silicone rubber.
Silicone Coolant Hoses
Silicone coolant hoses, used in industries such as automotive and HVAC, are renowned for their heat resistance. They outperform other materials in extreme temperatures, making them an excellent choice for such applications. However, they can be prone to electrochemical degradation if not properly manufactured or maintained. Therefore, ensuring quality control during production and regular maintenance checks can help mitigate these issues, enhancing the lifespan of these components.
Enhancing Durability With Inorganic Fillers
One way to bolster the durability of silicone rubber is by incorporating inorganic fillers. These fillers can improve the material’s resistance to heat, mechanical stress, and gas diffusion. For instance, adding silica fillers to silicone rubber can enhance its tensile strength, reducing the chances of degradation under mechanical stress. This strategy is beneficial, especially for applications that require robust performance over extended periods.
Optimizing The Manufacturing Process
A well-optimized manufacturing process can significantly reduce the risk of silicone rubber degradation. This includes ensuring precise temperature control during the curing process and maintaining cleanliness in the production environment. By doing so, businesses can prevent the introduction of impurities that might compromise the material’s integrity and performance.
Smoother Surface Finish For Better Performance
Lastly, a smoother outer surface finish can enhance the performance of silicone rubber products. A smoother surface reduces the chances of micro-cracks that can evolve into significant defects over time. It also minimizes the area of contact with potentially damaging substances, reducing the risk of degradation. For example, a smooth surface finish in medical tubing enhances durability and ensures consistent fluid flow.
