When talking about the materials of baby bottles, glass and plastic are undoubtedly the two most popular options. Glass is a traditional bottle material that are safe for baby use with high temperature resistance and containing no toxic chemicals. However, glass baby bottles appear to be relatively heavier and more fragile. Therefore, more and more parents would go for plastic baby bottles as an alternative for the glass one.
Indeed, plastic is a more practical material when comparing to glass. However, there would be some problems with plastic baby bottles like aging, wear and tear caused by repeating washing. Thus, the choice of the plastic is quite important. The plastic for baby bottles must be BPA-free, durable, and 100% safe for babies and parents. There are different kinds of plastic that are suitable for making baby bottles. PP, PES, and PPSU are three of most common bottle plastic types. They are all BPA-free and non-toxic. Next, let’s see how they differentiate as the material for baby bottles.
At present, PES feeding bottles have become increasingly popular by a large amount of parents. PES refers to polyethersulfone, which is also a high performance thermoplastic polymer. It has excellent chemical stability under high temperature and can withstand the temperature of 180℃. Nowadays, PES is regarded as one of the most practical engineering plastic.
PES baby bottles are durable, and can bear heavy impact and wear. They usually comes in a beautiful honey color. Besides, PES is highly creep, chemical, acid, base resistance, making it 100% safe and non-toxic for long-term high-temperature use. Thus, PES has become an ideal and popular plastic for baby bottles.
PP, with a full name of polypropylene, is the most common plastic used in baby bottles. It is a thermoplastic synthetic resin with high performance, usually coming in a colorless and transparent appearance. PP has outstanding chemical, heat, and insulating resistance, with high machinery strength and great processibility. Thus, baby bottles made from PP are durable and flexible, and can withstand the temperature of up to 110℃.
However, PP bottles can lose transparency as time goes by after repeating boiling, washing, and sterilization. In this case, the transparency loss has something to do with the change of bottle’s physical feature. Advisably, replace the PP bottle with a new one every 3 months to ensure the safety.
PPSU stands for polyphenylsulfone, which belongs to the family of high performance thermoplastic polymer. It is BPA-free, and a plastic that won’t react with color and odor.
With a high melting point of 208℃, PPSU has higher heat resistance than PP, and can withstand stronger impact and wear. Therefore, the PPSU feeding bottle can bear repeating sterilization, and even can be heated up by microwave. However, the drawback of PPSU is that it is expensive than PP and PESdue to its superior durability. With proper use, PPSU baby bottles can be used for a year without replacing.
As what is mentioned above, you can see the advantages of PES when used in baby bottles. It is a high performance plastic with high cost-effectiveness. Today, many manufactures of baby bottles and other plastic products would like to use PES as an alternative of PP and PPSU.
