Choose pp or pc for water cups?

1. Characteristics:

- PP: Polypropylene is a plastic material with good chemical stability and high heat resistance. It has excellent acid and alkali resistance and is not easily eroded by chemicals. In addition, PP has good resistance to grease and abrasion.

- PC: Polycarbonate is a transparent and strong plastic material. It has excellent impact resistance and high temperature resistance and can withstand high temperature changes.

2. Safety:

- PP: Polypropylene materials are widely used in food packaging and containers because they are non-toxic, odorless and do not release harmful substances.PP materials are safe under normal conditions of use and do not have a negative impact on human health.

- PC: Polycarbonate materials may release substances that are harmful to humans, such as bisphenol A (BPA), under high temperature conditions. Although many PC products have added doses to prevent the release of BPA, prolonged exposure to high temperatures may still pose some risk.

3. Durability:

- PP: Polypropylene has good abrasion resistance and durability, and can withstand daily impacts and friction under normal conditions of use. mugs made of PP materials are usually stronger and less likely to break or deform.

- PC: Polycarbonate material has excellent impact resistance and is not easy to break. However, PC material is relatively hard and may scratch easily.

4. Environmental friendliness:

- PP: Polypropylene is a recyclable plastic material that can be recycled to minimize the impact on the environment. In addition, the production process of PP materials is relatively more environmentally friendly, which can reduce resource consumption and waste emissions.

- PC: The production process of polycarbonate is relatively complex, involving organic synthesis and high energy consumption. In addition, PC materials are not easily degraded during processing, causing potential negative impacts on the environment.

To summarize, a better choice is to choose water cups made of PP, which has excellent chemical stability, heat resistance, acid and alkali resistance, is safe and reliable, and will not have a negative impact on human health. In addition, PP water cups also have better durability and environmental performance. Of course, in the actual choice, but also according to personal needs, the use of the environment and budget to weigh and make decisions.
