Is it bad for your health to use the same plastic cup for a long time?

As long as you don't pour too hot water, you'll be fine

Yes.

Plastic cups refer to disposable containers used to hold beverages and tea. It is a non-degradable product and is the main ** of "white pollution". The largest use of disposable plastic cups is generally in beverage shops, hot and cold drink shops, bubble tea shops, hotels, restaurants and coffee shops, providing a variety of plastic cups for takeaway drinks and on-site use.

This kind of cup is a non-degradable product, and plastic cups drink water, and if you drink hot water, it may be harmful to the human body. If you drink cold water, it is generally on the body. 1. Harmful:

Plastic is a polymer chemical material, and when hot or boiling water is filled in a plastic cup, the macromolecules are easily separated. 2. No harm: plastic cups generally belong to food grade, made of polymer, usually have no effect on the body, drink cold water.

In daily life, if there are uncomfortable symptoms, you should seek medical attention in time for examination, and carry out ** in time.

Plastic cups are harmful to hot water.

Plastic cups should not be filled with hot water. In addition to being heated, plastic cups are toxic except for the precipitation of some chemicals.

Plasticizers are often added to plastics, which contain some toxic chemicals, when hot water or boiling water is filled with plastic cups, toxic chemicals are easily diluted into the water, and the internal microstructure of plastics has many pores, which hide dirt, and it is easy to breed bacteria if it is not clean.

Molecular structure of plastics

There are basically two types: the first is the linear structure, and the polymer compound with this structure is called the linear polymer compound; The second type is the body structure, and the polymer compound with this structure is called the body type polymer compound.

Some polymers have branched chains, called branched polymers, which belong to the linear structure. Although some polymers have cross-links between molecules, there are fewer cross-links, which are called network structures, which belong to the body structure.

Two different structures that exhibit two opposing properties. Linear structure, heating can melt, less hardness and brittleness. The body structure is more rigid and brittle.

It depends on whether the material is resistant to high temperatures. For example, PP material is resistant to high temperatures. PS material is not resistant to high temperatures.

1. The PP plastic water cup is made of polypropylene, which has good thermal stability and insulation, safety and harmlessness to the human body. The product can be sterilized at a temperature of more than 100 meters, and under the condition of not being affected by external force, 150 meters will not be deformed, and there is no pressure in boiling water.

2. The PET material cup is heat-resistant to 70, and can be filled with room temperature water for a short time, and cannot be filled with acid-alkaline drinks or high-temperature liquids, nor should it be exposed to the sun, otherwise it will produce toxic substances harmful to the human body.

3. The plastic cup made of PS material is particularly brittle, low temperature resistance, and cannot be used in high temperature, strong acid, and strong alkali environment.

4. AS (acrylonitrile-styrene resin), PC material and other categories, used in pots, cups, feeding bottles, etc., with high safety and drop resistance, but not high temperature resistance. It is not harmful to drink cold water, but if it is filled with hot water, it will produce substances that are harmful to the human body.
