Plastic itself has certain chemical substances, and some organic polymer structures in plastic will be decomposed into small molecular organic substances, and boiling water will undoubtedly accelerate this process. Organic small molecules are distributed in water, so it is still unsafe and hygienic. Don't use them to boil water.
In daily drinking water, bottled water such as mineral water should not be placed in high temperature or direct sunlight for a long time. The high temperature inside will also dilute the harmful substances in the bottle, so this water should be stored at room temperature or low temperature.
At high temperature, industrial plastics will dilute all kinds of harmful substances, even toxic substances, according to different components, resulting in water pollution. If people drink it, it will affect their health and even lead to serious consequences such as poisoning. If boiling water is used, it is relatively safe to choose a container made of 5pp.
Extended data:
The performance characteristics of engineering plastics are as follows:
(1) Compared with ordinary plastics, it has excellent heat and cold resistance and excellent mechanical properties in a wide temperature range, and is suitable for use as a structural material.
(2) Good corrosion resistance, little environmental influence and good durability;
(3) Compared with metal materials, it is easy to process, has high production efficiency, can simplify working procedures and save costs;
(4) Good dimensional stability and electrical insulation;
(5) Light weight, high specific strength and outstanding antifriction and wear resistance.
