Whether you’re a seasoned player in the industry or a newcomer seeking to understand the mechanics of extrusion, this comprehensive guide will equip you with the knowledge you need to make an informed decision.

Different Methods of Extruding Materials

Let’s look at what the extrusion process entails, the various methods of extruding materials, and how the different methods compare to one another.

An Explanation of the Extrusion Process

The extrusion process involves forcing a material through a die (an opening set to produce a specific cross-sectional profile). This process uses high pressure and temperature to accomplish it.

As the material emerges on the other side of the die, it takes on a new form, reflecting the shape of the die. Depending on the method and the material, the extruded product can have unique characteristics that are suitable for various applications.

Different Methods Explained

Several methods can extrude materials. The most common methods are hot extrusion, cold extrusion, warm extrusion, and dual extrusion.

  • Hot extrusion involves heating the material above its recrystallisation temperature, making it easier to push through the die.
  • Cold extrusion occurs at room temperature or slightly warmer than room temperature.
  • Warm extrusion combines elements of both, occurring at temperatures between room temperature and the material’s recrystallisation point.
  • Dual extrusion merges two different materials in one process, which is ideal for creating composite profiles.

The Pros and Cons of Each Extrusion Method

Each extrusion method has its advantages and drawbacks. For example, hot extrusion allows for a higher rate of production and reduces the need for finishing processes. However, it can be more energy-consuming.

Cold extrusion, on the other hand, enhances the strength and hardness of the material, but it may be unsuitable for materials with low pliability. Weighing these factors will help guide your selection of the right extrusion method for your desired outcome.

Silicone rubber is one of the most popular materials around the world, but it has proven to be especially popular in the medical and pharmaceutical industries. At Viking Extrusions, we have helped many organisations in these industries get the medical-grade silicone rubber products they need. So how have those companies been using silicone rubber?

What is medical-grade silicone rubber?

Medical-grade silicone undergoes a different curing process than conventional silicone. The peroxide curing system leaves behind an acidic residue as a by-product, which makes it unsuitable for medical applications.

The silicone used in medical and pharmaceutical organisations must pass a biocompatibility test. Platinum-cured silicone is the best method for ensuring silicone is appropriate for use in medical situations.

How the pharmaceutical and medical industries use silicone rubber

One of the best things about silicone rubber is how diverse a material it is. It can be used in so many different applications and forms, depending on the needs of your business.

Silicone rubber tubing is common within medical and pharmaceutical industries. Our platinum-cured silicone tubing has excellent biocompatibility and high tear strength, making it suitable for medical applications. It is extremely hygienic and is manufactured in an ISO 9001 and ISO 14001 facility.

Is medical-grade silicone safe for my business needs?

Medical-grade silicone is one of the safest silicone rubber variants on the market. It boasts a number of properties to make it perfect for pharmaceutical applications.

Sterile material

Platinum-cured medical-grade silicone is biocompatible. It is also non-porous, making it impervious to water and easier to clean. as well as reducing the chances of germs and bacteria building up.

Chemically stable

Silicone rubber is resistant to numerous chemicals, such as those found within medical environments. It can be exposed for significant lengths of time without the integrity of the product being compromised, making it perfect for pharmaceutical companies seeking long-lasting products.

Long-lasting and durable

The lifespan of silicone can vary, depending on the way it is cured and the environment it is used in. Depending on the curing process, it can last upwards of 45 years. The durability makes these products key for medical and pharmaceutical organisations, as they can withstand a great deal of pressure and punishment in harsh environments.

Temperature resistant

The temperature range of silicone, before it becomes brittle or begins to deteriorate, is extensive. It can reach temperatures as low as -50°c and reach up to 300°c. It has one of the best ranges, making it perfect for use in the pharmaceutical and medical sectors.

A suitable material for use in a range of applications, silicone rubber has become one of the most popular materials across the world. With uses in all industries, it is a long-lasting high-performance polymer that can transform the way your business works. So what is the expected lifespan of silicone rubber and what factors affect it?

What is the typical silicone lifespan?

The lifespan of silicone rubber varies depending on the way it is cured, the form it takes, and a number of other factors. As a general guideline, silicone tends to have a long shelf-life of around 20 years.

However, the curing process for platinum-cured and peroxide-cured silicone can extend the life, with some silicone rubber profiles lasting upwards of 45 years. If you’d like further information on silicone lifespans and how we can formulate specialist grades of silicone to suit your needs, you can contact the Viking Extrusions team to discuss your requirements in detail.

How long does it take for silicone to decompose?

Silicone can lose its integrity and properties over time. This could be caused by numerous factors or simply the material itself reaching the end of its life. It is not affected by general weathering, UV, or ozone exposure, making it ideal for use outside in a number of applications.

It is an extremely durable material, and as a result, silicone rubber can take anywhere from 50 years to 500 years to decompose, making it the long-lasting product many businesses need.

Does silicone break down and what factors can alter the lifespan of silicone rubber?

There are multiple benefits of using silicone rubber. That said, the quality and integrity of silicone rubber can be affected by numerous factors, from exposure to specific chemicals to use outside of the temperatures it can withstand.

  • Temperature – The temperature range of silicone rubber can go as low as -70°c and as high as 300°c. However, exposing the material to temperatures outside of this range can cause the material to degrade significantly.
  • Chemicals and oils – Silicone can tolerate some exposure to chemicals and oils. However, if it is to be exposed for longer periods of time, you will notice that silicone will swell. A specialist-grade silicone can prevent swelling.
  • Damage – Silicone rubber is extremely durable as a material and able to withstand a lot of pressures. However, significant damage to the material, such as cutting or tearing, can weaken the overall integrity. If you expect the silicone to be exposed to elongation and significant force, a specialist-grade silicone might be better suited to your needs.


Is silicone eco-friendly?

The durability of silicone rubber means that it will not break down into smaller pieces, as plastic does. It will only break down with external assistance. Its long lifespan makes it a popular choice for businesses, and we have manufactured over 8,000 silicone rubber profiles for customers throughout the years. One key element is that it isn’t likely to pose a risk to wildlife as it is not small enough to be ingested. In some cases, it can be recycled.

In a blog post from Operations Manager Matthew Bishop, we explored the topic of making silicone circular:

"At present, silicone is not recycled as much as it should be. Perhaps the most important reason for this is that silicone is difficult to break down, which makes recycling expensive and discouraged. This resistance to chemical degradation is also why silicone is so highly valued – and possibly the reason why we have been so slow collectively to recycle and reuse it. Silicone is not like plastic. It does not break up into microplastics and, if landfilled, it generally holds together and could resist the environment for at least 500 years. This actually makes silicone environmentally friendly, in a way. If silicone is dumped into the environment, it just sits around doing nothing. It doesn't make its way into the oceans or food chains and is therefore easy to ignore. This is a mentality that must change."
