If someone mentions the word “silicone,” plenty of different images can come to mind. However, when it comes to the realm of gaskets and sealing systems, the use of silicone seals is rather specialized. Although its span of applications may be surprising, looking at the characteristics of the material and how it’s utilized, reveals that silicone is the real deal.

For Medical Applications

One of the ways silicone has been found to be useful is in various applications pertaining to the medical world. Organically based, silicone offers thermal stability, biocompatibility, and has a naturally low modulus (meaning that it’s flexible, elastic and soft), which works well for the needs of many devices. In terms of processing, silicone tends to require less additives and can be formulated for medical and FDA applications more easily. Here are a few examples of how it’s used in this case:

• Syringe plungers
• Baby nipples
• IV Connector seals
• Hearing aids (in terms of insulation & fit)
• Drug testing kits & Diabetes glucose level kits
• Device covers

Handling the Heat…& the Cold

Another specialized use of silicone has to do with the aspect of temperature. Due to the fact that silicone rubber maintains excellent heat resistance, it has proven itself suitable for several applications where high/dry heat is a factor. Oven seals and insulation, welding equipment, hot air exhaust systems and manifold seals all can benefit from silicone’s stability and performance in the face of increased temperature.

Even on the opposite side of the spectrum, silicone is still able to retain its physical properties when temperatures get low. Here, silicone reveals its capacity for being used in applications of high temperature range. For example, in electronic actuators, sensors, seals for instrumentation and in lighting applications, silicone is able to provide durability towards either end of the temperature gauge.

Catering to Shape & Aesthetics

Other applications have discovered that silicone rubber suits their aesthetic needs to a tee. Once again, its low modulus provides the softness that applications like button covers, handles, or display bumpers, desire. To enhance silicone’s aesthetic appeal, it typically adds the benefit of being able to be colored with more vibrant and brilliant hues.

Silicone can also be molded into elaborate or complex shapes. As a raw material, silicone can be more expensive than other rubber materials, but its unique properties can more easily cater to molding processes where pliable substances are needed. So, when certain parts like complex connectors are required, many turn to using silicone to get the job done.

It probably comes as little to no surprise that products rely on various materials and components in order for them to perform successfully. But what may be a little less clear is the question of what’s rubber got to do with it? The fact is that engineered rubber materials have got quite a lot to do with it. For thousands of products every day, they rise to the occasion and overcome application challenges in which other materials fall short.

What’s Engineered Rubber & What is it Used For?

Engineered rubber materials have earned their status due to their unique physical properties and ability to meet performance objectives. Also referred to as elastomers, they provide toughness in the face of application challenges where pressure, wear, impact and other factors are concerned.

When it comes to rubber, several types are available. However, a plethora of variables are also involved that can affect performance, including formulation and temperature. Through the blending and combining of different ingredients, along with the 14 basic polymer groups, engineered rubber is formulated to meet specific design needs. Its specialized nature leads to its enormous span of application uses. Just check out a few examples of its range:

• Engineered rubber can be used for sealing in applications where liquid is manipulated, including fuel systems, valves, hydraulics and beverage dispensing.

• It can be used for sealing in applications that manipulate air media such as pneumatic systems, heat ventilation and exhaust, diaphragms and riveting equipment.

• The high-performance capabilities of engineered rubber also suit preventative or protective applications like impact absorption, wear resistance and crash stops, vibration dampening and the exclusion of dust debris.

• In addition, it can be used for functional applications such as insulators, isolators, drives and linkage parts, as well as aesthetic applications like mounts, caps, plugs and protectors.

Engineering the Solution

Undoubtedly unique, engineered rubber materials have proven themselves to be just the right answer to many application needs. This is especially true when materials like metal and plastic cannot fulfill the requirements. However, understanding the needs and parameters of a specific application challenge is just the beginning.
