What kinds of plastic cups are there? The raw material of 1.pet plastic cup is high-pressure polyethylene terephthalate. The common beverage bottles and mineral water bottles in large supermarkets are made of these raw materials. The temperature resistance of pet is only 70℃, so people will deform when pouring hot water, and frequent use will endanger our physical and mental health.
2.HDPE plastic cups HDPE plastic cups are made of high-density polyethylene and are common raw materials for shampoo and shower gel at home. This kind of raw material will be deformed under continuous high temperature and is not suitable for hot water pouring.
3.pvc plastic cups pvc plastic cups are made of polyvinyl chloride, which is basically the raw material of domestic water pipes. This material will release harmful substances at high temperature and is not suitable for pouring hot water.
4.pp plastic cup The raw material of pp plastic cup is polypropylene, which can resist temperature up to 1 10℃- 150℃ and does not contain bisphenol A (toxic substance), so it belongs to a food-grade plastic with excellent safety factor. It is a popular glass baby bottle material, which can be poured with hot water.
5.ps plastic cup The raw material of ps plastic cup is polystyrene, which is commonly used in our barreled instant noodles. Although this material is not easy to release harmful substances, it has weak temperature resistance and is not suitable for pouring hot water and microwave heating.
6, pc material plastic cups pc material is more common in our lives, many cups and bottles are made of these raw materials. Although the temperature resistance of this material can reach 135℃, frequent use at high temperature will release bisphenol A, so it is not recommended to pour it into boiling water for a long time.
7.tritan plastic cup tritan, also known as modified pvc, is a popular cup material at this stage. Its highest temperature resistance can reach 109℃, and it is not easy to release bisphenol A after pouring into boiling water.
8. PPSU plastic cup PPSU material is polyphenylene sulfone epoxy resin, which has strong temperature resistance and reliability, and the highest high temperature resistance can reach 220℃, so it is widely used in glass bottles, and PP has more excellent properties and is an excellent plastic material.
Is it suitable to pour hot water into a plastic cup? As can be seen from the above, hot water can be poured into plastic cups made of PP, pc, PPSU and tritan, but it is not recommended to pour hot water into cups made of PC for a long time. Due to too frequent application, bisphenol A will precipitate scientifically, but if it does not exceed 100℃, normal use will be fine.
