As fellow mums, we get your concerns. We understand that choosing to give your baby a bottle isn’t always a simple decision. Especially when you start looking into the various hidden materials from which some baby bottles are made from. As parents, we have a right to be concerned about nasties such as phthalates, bpa, lead, mercury and other toxins.

Choosing safe baby bottles: PPSU vs other materials

Care to know more about our medical-grade PPSU bottles? In this article, we’ll share more information about these bottles and what they are made of. We’ll do this by comparing PPSU vs other baby bottle materials and share their pros and cons. Also, we’ll discuss the benefits of using PPSU baby bottles and why they are worth the investment for your baby.

but first … let’s look at different baby bottle materials

To understand the difference between different baby bottle materials, let’s have a look at their pros and cons.

1. PPSU (Polyphenylsulfone)

2. PP (Polypropylene)

3. Plastic


PPSU (Polyphenylsulfone)


Thinking of all those nighttime feeds that require a bottle? One that can withstand high levels of usage? PPSU is a medical-grade, long-lasting plastic that's naturally honey-toned and incredibly hard-wearing.

It’s made of crystal-clear solid material and is the 'gold standard' when it comes to baby bottles. Firstly, it’s highly resistant to heat and impact, making it a safe choice for your baby's feeding needs.

This means it can handle both hot and cold liquids without affecting the bottle's shape or texture. It’s also free from BPA, BPS, and other harmful chemicals, ensuring your baby's health and safety.

It is very lightweight and temperature resistant (up to 180 degrees Celsius) without any release of toxic substances. It’s also easy to clean and sterilise, making it a convenient dependable choice for busy, on the go mamas!

By selecting a medical-grade PPSU bottle, you can be confident you’ve chosen one that will stand the test of time.


PPSU baby bottles are more expensive compared to some other materials such as PP, but the investment is worth it in the long run. This is due to them being more costly to manufacture as they are built to last. For a bottle that will last for baby and beyond - a PPSU bottle is the one you need.

PP (Polypropylene)


PP is the material most baby bottles are made from. It is a lightweight and durable plastic that is safe for use with baby bottles. These bottles are affordable and widely available in the market. They are also BPA-free, making it a safer option for your baby's health.

However, it must be noted that they are less durable. They also age faster and have lower heat resistance. However, these bottles are still deemed safe, free of toxins, and are ergonomic and lightweight. PP bottles are strong enough to withstand standard bottle cleaning methods, however, cannot withstand high temperatures.


PP is not as heat resistant as PPSU and may deform or become brittle when exposed to high temperatures. It is also prone to losing its luster with frequent use. If so, replace them at the first sign of weakness. For this reason, we recommend PP for light use only.



Plastic baby bottles are known to be lightweight, strong, unbreakable, durable, and affordable. They are also widely available in the market, making them a convenient choice for parents. If you’re buying these bottles brand-new, you can also rest assured that they’re relatively safe from nasties. This is because those available in the marketplace today are largely chemical-free. However, do replace a plastic baby bottle if it is cracked, leaking, discolored, or has a funny aroma.


Plastic bottles may contain harmful chemicals like BPA and BPS, which can be harmful to your baby's health. They are also not as heat resistant as PPSU and may deform or become brittle when exposed to high temperatures. Also, plastic baby bottles may not last as long as glass. And if you’re using older, secondhand bottles, they may still have bisphenol A (BPA), a chemical used to make hardened plastic. While the FDA banned the use of BPA in 2012 from baby bottles, the older ones may still have it.



Glass baby bottles are safe and do not contain harmful chemicals like BPA and BPS. They are also durable and can handle both hot and cold liquids without affecting the bottle's shape or texture. They last a long time, and you can boil them for a deep clean. It’s best to sterilise new glass baby bottles and nipples by putting them in boiling water for 5 minutes.

Thereafter, you can wash bottles in the dishwasher, or wash by hand with hot, soapy water and rinse well. Our word of warning? Do replace a glass baby bottle if it’s cracked or chipped. And especially if you find a certain set just doesn’t agree with your baby’s needs!


Glass baby bottles are heavier compared to plastic and PPSU, which could make holding them more difficult for baby and less convenient for busy parents. They are also more prone to breaking if dropped, making them a less practical choice for some parents.
