A pc cup can be used to drink cold water, but it is not recommended to drink hot water. Because PC polycarbonate, the cup made of material is not resistant to high temperatures. If it is heated or placed in an acid or alkaline environment, it will easily release the toxic substance bisphenol. Therefore, do not use it to hold hot water, and it is best to use warm water for cleaning.

Can the pc plastic cup still be used after receiving hot water?

1. PC plastic cups can still be used after receiving hot water, but they need to be treated with caution and decide whether to continue using them according to specific circumstances. PC cups that meet safety standards should be made of safe PC materials at the specified temperature and below the specified upper limit of use temperature. Containers containing bisphenol A are safe and will not produce toxicity.

2. It is not recommended to continue using it. Although PC plastic itself is resistant to high temperatures, it may release bisphenol A (BPA) when exposed to hot water, and long-term intake poses potential health risks. PC (polycarbonate) material itself has good high temperature resistance and can usually withstand temperatures of around 100 ° C. However, the bisphenol A (BPA) added during the production process is the main hidden danger. This substance may precipitate out of plastic at high temperatures or long-term use, and the risk of migration is higher especially when encountering hot water, acidic or oily liquids.

3. The PC plastic cup can still be used after receiving hot water, but it needs to be treated with caution. PC plastic, or polycarbonate plastic, is a widely used material with the advantages of high transparency and strong impact resistance. It is often used to make daily necessities such as water cups and milk bottles.

The plastic cup has been filled with hot water for a long time. Can the water behind it still drink?

1. After filling plastic cups with hot water for a long time, you need to be cautious when filling water, mainly depending on the material and frequency of use. Material determines safety. Plastic water cups usually have a triangular recycling mark number on the bottom.① [No. 5 PP material]: High temperature resistance (about 120℃), suitable for microwave ovens, it is safer to repeatedly load hot water, but it is recommended to replace it in about 1 year.

2. If the material of plastic cups that hold hot water for a long time is not resistant to high temperatures or has aged, it is not recommended to continue drinking the water that is subsequently held. Core problem analysis The high temperature resistance of plastic water cups mainly depends on the material. Common materials on the market such as PC (polycarbonate) may release substances such as bisphenol A at high temperatures, while PP (polypropylene) or Tritan (copolyester) have better resistance to high temperatures.

3. After filling the plastic cup with hot water for a long time, it is not recommended to drink the water directly. Risk of material change Most plastic water cups are not resistant to high temperatures, and long-term filling of hot water may cause the material to age or release chemical substances (such as bisphenol A, plasticizers, etc.). Even if the cup is used again after cooling, changes in the microstructure of the inner wall caused by high temperatures may leave impurities and affect the safety of water quality.

4. Whether hot water can be drunk in a plastic water cup for a long time depends on the specific material and storage conditions. Safety of common plastic materials: There is generally a triangular recycling mark on the bottom of the plastic cup, and a numerical number in the middle: No. 5 PP material (polypropylene): resistant to high temperatures (about 130℃). It is filled with boiling water and is non-toxic and can be used with confidence.

5. After holding hot water in a plastic cup for more than 4 hours, it is recommended not to drink it. The safety of plastic materials is closely related to hot water contact time. Among the triangular numbers on the bottom of common plastic cups, No. 5 PP material and No. 7 Tritan material are relatively resistant to high temperatures and safer to fill hot water. However, even for high-temperature resistant materials, long-term (more than 4 hours) high temperature immersion may cause changes in the microstructure of the plastic and trace amounts of plasticizers may be precipitated.

6. Plastic cups that hold hot water for a long time are not recommended to continue to be used, as they can easily release harmful substances and breed bacteria. Most plastic cups are made of PET or PC, which has limited stability at high temperatures. If hot water is filled multiple times or stored for a long time, it will easily accelerate the aging and deformation of the plastic. Repeated heating will cause cracks or even discolor on the wall of the cup. Continuing to use it at this time may easily lead to two hidden dangers.

Can the pc water cup still be used when it falls into a small crack but it does not leak?

No. The pc water cup fell out of a small crack, but it didn't leak and could not be used. A small crack appeared on the pc water cup. Although it does not leak, as the use time goes on, this small crack may expand. There is a possibility of explosion when filling hot water, which may cause injury.

Usage suggestion: Once a crack or damage is found in the plastic water cup, stop using it immediately and replace it with a new water cup. Avoid using cracked or aging plastic appliances to reduce potential health effects. In short, in order to ensure the safety and health of drinking water, it is recommended to replace plastic or plastic cups with cracks in time.

After jumping over the water cup, whether the water cup can still be used mainly depends on the degree of damage and the material. If the water cup is only slightly bumped: slight scratches or dents may appear on the surface, but no cracks or leaks appear. This degree of damage to the water cup usually does not affect its tightness and use function, so generally speaking, it can continue to be used.

If the crack is shallow and is not used for drinking hot water, it may be used in a short period of time, but for health and safety reasons, it is still recommended to replace the cup with a new cup as soon as possible.

It is not recommended to continue using the plastic water cup after it has cracks. The following are the specific reasons: Material decomposition: A crack in the plastic water cup means that the plastic material has begun to decompose. This decomposition process may release small molecule products that may have adverse effects on human health. Microbial breeding: Cracks can easily become breeding grounds for microorganisms, which may contaminate the water in the glass and pose a threat to human health.
