Does plastic water cup choose PC material or PP material?

There are various types of plastic drinking cups on the market. When we choose plastic water cups, we will inevitably be dazzled.

In order to let everyone know more about plastic water cups, we can choose the plastic water cup that we like. Let me focus on introducing the differences between PC and PP in the plastic water cup material.

1.PC Material

PC is the English abbreviation for polycarbonate and is one of the most common plastics. This material is non-toxic, especially used to make baby bottles, space cups, etc., but because it contains BPA, it has been controversial.

Theoretically, as long as 100% BPA is converted into a plastic structure in the process of manufacturing polycarbonate, it means that there is no BPA in the product at all, so there is no threat to health. However, if a small amount of BPA is not converted into a polycarbonate plastic structure, it may be released into food or beverages, threatening the health and safety of users, especially teenagers.

2.PP Material

PP is the English abbreviation for polypropylene and has good heat resistance. The product can be sterilized at a temperature above 100 degrees Celsius, and without external force, it will not be deformed at 150 degrees Celsius. Polypropylene is one of the most commonly used plastics in microwave ovens. However, after careful investigation, we will find that polycarbonate on the market is often more expensive than polypropylene products, and customers tend to follow the concept of "the more expensive, the better the quality." In fact, the price difference is because the price of one ton of polycarbonate on the market is much higher than the price of one ton of polypropylene.

3.The Difference between PC and PP

Comparing the two materials, it can be found that the wear resistance of polypropylene is lower than that of polycarbonate, so polycarbonate is generally used as the material when making transparent cups, and polycarbonate products are more beautiful than polypropylene products.

However, from a safety point of view, the processing temperature of polypropylene plastic reaches 170 to 220 degrees Celsius, so boiling water cannot decompose it, so polypropylene is safer than polycarbonate.
