PP or PC cup, which is better?
With the continuous progress of society, the industry is more and more developed, people are very fond of plastic cups, which are simple and light, and the utilization rate is relatively high, so they often use plastic cups to drink water, but many people have different ideas. Which kind of water cup is safest to drink? This idea is also very reasonable, after all, the plastic cup contains a lot of chemicals, usually we need to know more about household drinking water, so that this problem can be solved.
We all know that the safety of plastic cups of different materials is different. Which kind of plastic cup is PC or PP plastic cup? PC cup plastic cup light transmittance is better, and lighter than glass, low price, generally can heat up to 100 ℃, with a very good impact strength, thermal stability, glossiness, inhibition of bacterial characteristics, the PC cup plastic cup light transmission, light than glass, low price, generally can heat up to 100 ℃, with excellent impact strength, thermal stability, glossiness, inhibition of bacterial characteristics, Flame retardancy and pollution resistance. But after repeated heating will produce carcinogens such as bisphenol-A, so Europe and the United States, Southeast Asia, Japan, South Korea and other countries have issued a ban on PC materials used in baby products.
The PP plastic cup is relatively light, is not easy to crack, has good heat resistance, no doubt, stability and safety of toxic substances, and the only drawback is that the light transmission is slightly poor. The strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP was 150 ℃. The material has good surface rigidity and scratch resistance due to the high degree of crystallinity. and the PP material is more resistant to acid and alkali than the PC, and the plastic cup of the PP material is also the only plastic box which can be put into the microwave oven, and can be repeatedly used after being carefully cleaned
After comparing the characteristics of PC plastic cup and PP plastic cup, we all can't see that it is better to use PP plastic cup in life, because the material of PP plastic cup is obviously due to PC plastic cup, and it is also very high-temperature resistant. Almost no toxic substance is produced. Baibai safety net editor reminds you that plastic cups are better than PP
