What are the different characteristics of different drinking water bottle materials?

Water bottles are the most common drinking bottle used in daily life, working, camping, at school, fitness, and shopping. There are many different materials of water bottles, such as high borosilicate glass, plastic, Tritan, stainless steel and etc. Each carries its own advantages and disadvantages. But what are the different characteristics of these materials? Do these materials easy to carry? Do these materials damaging to our environment? Now let’s take a look at these things.

Is high borosilicate glass the best material for drinking water?

Most people don’t know the difference between glass and borosilicate glass. Borosilicate glass is a type of glass, which contains silica and boron trioxide. The weight of borosilicate glass is lighter and harder than normal glass. Borosilicate glass has a very low coefficient of thermal expansion and can withstand temperatures up to 165 degrees (297 Fahrenheit), which means it will not be broken under dramatic temperature changes. All pure borosilicate glass is 100% BPA-free. If handled c, borosilicate glass can use for a long time.

There is no danger of inorganic chemicals leaching into liquids when it’s heated or cooled; it’s safe to drink any liquid. So it is widely used in producing drinking bottles, teapots, food storage pots, cookware, lighting, decorations and etc. But glass can easily be broken, and it’s very heavy, so it is recommended to use it indoors.

Glass can be recycled endlessly, so it does harmless to the environment.

Is plastic the best material for drinking water?

Lots of people prefer to buy single-use plastic water bottles because they think that’s recyclable. Each time they drink out the water, they throw the bottles in the recycling bin and think this is good for the environment. Single-use water bottles are made of PET (polyethylene terephthalate), 70% of them will not be recycled and dumped in the landfill, and it takes decades or even hundreds of years to degrade.

Most reusable plastic water bottles are manufactured from plastic polymers such as polypropylene (PP). Polypropylene (PP) is usually considered safe for humans because it is high heat tolerance. PP plastic water bottles are free of the chemical bisphenol-A (BPA), it will not release toxic substances then fulfilling with hot water or cold water.

Polypropylene (PP) has a relatively slippery surface and is very resistant to absorbing moisture. PP also has good chemical resistance, so we commonly used PP water bottles to fulfill energy drinks, juice, or coffee to bring out.

Is Tritan the best material for drinking water?

At the first, we need to know, what is Tritan?

Tritan Copolyester is a thermoplastic developed by the US company Eastman Chemicals in 2007 and is characterized by its practical and innovative properties

Tritan is not only BPA-free but also free from BPS and all other bisphenols.

This ultra-tough option features high impact and heat resistance. It’s also leach-proof, dishwasher safe, and resistant to odors, tastes, and stains. 

Bottles made of Tritan are very lightweight and perfect to take to the gym, office, or school. Tritan is shatter-resistant, so it has the gloss and sparkle of the glass, but won’t break or crack like glass. And it won’t dent or ding when it takes a tumble like stainless.

Tritan plastic is dishwasher safe, and it won’t warp in the hot water. It also won’t lose its luster wash after wash.

Is stainless steel the best material for drinking water?

But what’s the difference between stainless 304 and 316?

The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel, and 2% molybdenum. Most stainless steel thermos bottle around the world is 304. It offers standard corrosion resistance, formability, strength, and easy maintenance. Stainless steel 316 offers vastly superior corrosion resistance to chlorides and acids. It’s widely used in medical equipment and implants, foodservice, medical equipment and etc.

The corrosion resistance of stainless steel 316 is better than 304, so we recommend using it to drink milk, coffee, or tea, but only use stainless steel 304 to drink hot/ cold water. However, stainless steel is 100 percent recyclable.


No matter what kind of reusable water bottle you decide to use, it will be good for the environment. Reusing water bottles will help to reduce the purchase of single-use plastic bottles, and in a long time to save the environment.
