Is a space cup good for boiling water? Is a space cup poisonous to drink boiled water?

The space cup is suitable for boiling water.

[Reason].

1. Material safety

The space cup materials are all without exceptionPC plastic

PC is polycarbonate.

Abbreviation, PC material.

In fact, it is what we call engineering plastics.

As a widely used material around the world, PC is an amorphous thermoplastic resin with excellent comprehensive properties.

It has excellent electrical insulation, elongation, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance; It also has the advantages of self-extinguishing, flame retardant, non-toxic, and colorable.

2. Good thermal conductivity

Without a kettle cover, it's hard to imagine holding your single-layer metal kettle when it's filled with boiling water, plus it's good enough for ice hands in cold conditions. The disadvantage of low thermal conductivity of PC plastic becomes an advantage here, although the heat retention cannot be compared with the double-layer thermal insulation kettle, it is enough to ensure the comfort of the hand in various environments, and of course, there is no need to worry about running out of hands when filling boiling water.

3. Cheap

Domestic brands in supermarkets are only a few dollars to a dozen yuan, and even the well-known American Nalgene usually does not exceed 100 yuan.

7. Shape: You can see all kinds of strange shapes of space cups, round, rectangular, oval, with handshakes, waist in the middle, crooked handles, etc., etc., in short, how to look good, how to drink, how to carry, you can design as you like.

4. Health

PC plastic itself is non-toxic, odorless, and chemically qualified.

Stable, does not react with acids and bases, and there is no concern about excessive exposure to aluminum with certain metal kettles over time. Domestic, imported, how to choose.

Here I have selected 8 space cups as a comparison, 4 domestic products of different brands (upper row), 4 American Nalgene (lower row), I believe that through such a representative comparison, we can draw a more intuitive conclusion.

The plastic used in the space cup can fully withstand the high temperatures of our lives, so you can drink it with confidence.

Harmful, the use of PC material is more common in space cups, and bisphenol A

It is used in industry to synthesize materials such as polycarbonate (PC). Polycarbonate is a transparent hard plastic that is commonly used in the manufacture of baby bottles, for example.

Low-dose bisphenol A has carcinogenic effects, and high-dose nuclear culture bisphenol A is associated with cardiovascular disease.

The incidence is related to bisphenol A and estrogen.

This can lead to feminization of the baby.

PC Material Products:

It is relatively stable in water, but if heated to 150 degrees Celsius.

Bisphenol A will dissolve in water, and it will easily precipitate and dissolve in it when it encounters materials such as acids and oils. Therefore, if you change the Qiwei fruit to pour boiling water, repeatedly disinfect, and put it in the microwave oven to heat, it will cause a rapid increase in the dissolution amount of bisphenol A, which is a potential safety hazard.

Larger. When purchasing these plastic containers, you should pay attention to check the product production license.

Check if there is a triangle symbol on the bottom of the bottle, which means that it is made of PC, which may contain bisphenol A.

1. Light weight: much lighter than thermal insulation kettle or military kettle, and even lighter than Sigg Laken aviation aluminum kettle of the same specification.

2. Durable: Kaitong Bend, you may think that the transparent space cup looks weak, but in fact, today's space cup wheel is stuffy, whether it is the best Nalgene or a few dollars a domestic brand in the supermarket, their materials are all PC plastic without exception.

Space cups are cups made of food-grade polycarbonate and are a polymer. From a chemical point of view, this kind of basic Zen substance is generally very stable, it is not easy to degrade, and it is food grade, and it is not harmful to health.

Bisphenol A will be produced at high temperatures, which is harmful to health.

1.Its material is not only easy to degrade, safe, durable (but not suitable for high temperatures), and better than ordinary plastic cups.

2.It is comparatively lightweight and quite durable.

3.Construction: According to the model, this cup is easy to use when astronauts go to space, such as its screw cap and built-in nozzle, and the cup lid and the cup are connected together to prevent the cup lid from flying in weightlessness.

The main difference between the previous cups of the Space Cup is that there is a Grezeng in the middle of them, so that their heat preservation will be better.

OK.

58 in the triangle at the bottom of the plastic cup refers to the quality of the material is PC. Chinese name polycarbonate, the use of temperature -20 120, space group transport cup with this material, can ensure the safety of the cup.

58 means that the polycarbonate content in the raw material of the cup is less than 58%, which can be used with confidence to contain water or beverages, and can be used normally, without causing harm to the health of the human body.

Use temperature-20 120 The space cup is made of this material, and there is no problem with a good PC to hold hot water, but if the PC is not well processed, it will be heated and release bisphenol A, which is harmful to the body.

No. 2 HDPE high-density polyethylene.

Common white medicine bottles, cleaning supplies, stove beams, bath products. Do not use it as a drinking glass or as a storage container for other items. Do not recycle if you do not clean thoroughly.

No. 3 PVC PVC.

Common raincoats, building materials, plastic films, plastic boxes, etc. The plasticity is excellent and the price is cheap, so it is very common to use, and it can only withstand heat 81At high temperatures, it is easy to produce undesirable substances, and it is rarely used in food packaging.

It is difficult to clean and easy to remain, so do not recycle. Do not buy drinks if they are contained.

No. 4 PE polyethylene.

Common plastic wrap, plastic film, etc. Harmful substances are produced at high temperatures, and after the poisons enter the human body with food, they may cause diseases such as breast cancer and neonatal birth defects. Keep plastic wrap out of the microwave.

<>1. The space water cup can be filled with boiling water, but do not fill it with too hot water, because it will release bisphenol Xiang Duan Tong A for a long time, which is not good for the body. The composition of the space cup is polymethyl methacrylate, which is non-toxic, and high temperature will cause small molecule cleavage.

2. The main ingredient of the space cup is food-grade polycarbonate, which is a kind of polymer, from a chemical point of view, the combustion of this substance is very stable, it is not easy to degrade, and it is food-grade.

We are happy to answer for you, the following are the results for your inquiry: No, the space cup has the highest allowable temperature due to its low thermal conductivity, for example, the ceramic cup inside the space cup is safe and temperature-resistant 120, and the shell is temperature-resistant 90. If the water temperature is too high, there is a risk of scalding the mouth or hands of the forester.

In addition, if people want to put this type of hot water in a space bag, a better way is to use a hot compress technique to help the space cup rental resist temperature changes, such as semi-submerging the space cup in cold water, or taking the space cup out of the refrigerator and pouring hot water into the space cup, while allowing the space cup to create an insulation layer to keep warm. If you can do this, you can keep the hot water in the cup within a safe temperature range.
