What is Silicone?

What is Silicone?

Silicone is a material that is becoming more and more common in kitchens all across the country and there’s plenty of reasons why. It’s a safe, reusable and recyclable alternative to throw away plastics which is great news for the environment. But what exactly is silicone, how is it made and why are people touting it as the next big thing for keeping food fresh and tasty? Read on below as we unwrap the truth and answer these big questions and more. 

Is Silicone biodegradable?

No. But it can be easily recycled. Silicone products can be quickly broken down by specialised recycling companies and repurposed into things like oil for industrial lubricants and mulch for playgrounds. This process can be carried out multiple times and ensures that discarded silicone doesn’t end up in landfill. Many companies have take-back programs to make things easy for customers. 

What is silicone made from?

Despite what you might have heard, silicone doesn’t just come from sand at the beach. Instead, it’s actually a product of three different things.

  • Silica: the raw, natural material used to make silicone resins. 
  • Silicon: the base element of silica. It is made by heating silica at extreme temperatures with carbon in an industrial furnace. 
  • Silicone: the by-product of heating silicon 

To keep things simple, all you need to understand is that silicone borrows from each of these elements to make the products that we use on a daily basis, such as baby nipples, utensils, toys, bakeware and more.   

Comparing FDA approved silicone to LFGB certified silicone

Silicone that is sold to consumers must meet certain safety standards. This relates to food contamination and health problems that the products may cause. In Australia and the US, silicone products must meet FDA (Food & Drug Administration) testing requirements. Products sold in Europe (except France and Germany) must adhere to European Food Contact Regulations. While in Germany and France, LFGB (Foods, Consumer Goods and Feedstuffs Code) certification is required. LFGB testing is the most stringent and as a result, silicone products within this category are more expensive.  

The Pinch test

One way to determine whether you are looking at a product made from high grade silicone is to do the pinch test. This involves pinching or twisting a flat surface of a silicone product. If white shows through, then it is an indication that a filler has been used and it’s not pure. 

Why silicone is a better alternative to plastic

Silicone is a great alternative to plastic because it is reusable, washable and non-toxic. It’s also a much better option for the environment. These factors all make buying silicone products a smart move when it comes to protecting the health of you and your family, plus the planet too.
