There are many different plastic bottles on the market. I believe many people will have doubts: as plastic bottles have many different material, PC material and PP material and Tritan material, then for water drinking, which material would be better, no harm to our health ?
If it’s for only cold water, then we can use a PC plastic bottle. But if it is for hot water, then PP plastic bottle would be better. As I mentioned there are also Tritan material, which characteristics is better than PC & PP plastic material, then Tritan plastic is recommended for cold or hot water, both are safe for drinking.
PC is not recommended to hold hot water
This is because BPA (bisphenol-A) will be produced after the hydrolysis of PC material. Modern medical research believes that BPA may affect human health (including animals) if it exceeds A certain dose. For example, long-term intake of trace amounts of BPA will cause confusion in the endocrine system, which is very likely to have an adverse effect on the reproductive system and disrupt the balance of sex ratio. Therefore, some countries and regions have restricted or banned PC material.
The contrast of PP material and PC material
Comparing the PP plastic cup with the PC plastic cup, it is certain that the PP plastic cup is better than the PC plastic cup if we only take the cup making aspect.
PP material has higher temperature resistance than PC material, and it is also the only plastic material that can be put into the microwave oven. The thermal insulation performance of PP material cup are also better than PC material cup, and PP material is pure without toxicity!
However, the transparency of PP material is not as good as PC material, little frosted effect; and the strength of impact resistance of PP material is not as high as PC material. But in general, the cup made of PP material will be more safe!
The main hazard source of PC material cups is bisphenol A, and pp material does not contain BPA after testing, but it does not mean that pp material is absolutely safe, pp material cups with suspicious sources are more dangerous than PC material cups!
The contrast of Tritan material and PP material
summary:
1. Tritan material is superior to PP material, PP material is better than PC material
2. PC can only hold cold water
3. The hot water can be PP or Tritan. But Tritan is better than PP.
Therefore, Tritan is generally healthier and safer.
