Plastic products are everywhere in our daily lives. However, have you ever been concerned about the material safety of these plastic products? PE and PP are two common plastic materials, and they differ in many ways. In this article, we'll help you better understand the differences between the two materials by taking a look at the features and safety of these two materials.
PE plastic, the full name of polyethylene plastic, is a semi-crystalline thermoplastic. Due to its excellent low temperature resistance, good insulation, non-toxic and odorless characteristics, PE plastics are widely used in food packaging, medical supplies, household appliances and other fields. However, due to its low melting point, PE plastics are prone to deformation or release harmful substances at high temperatures.
PP plastic, the full name of polypropylene plastic, is a colorless translucent thermoplastic. Compared with PE plastic, PP plastic has a higher melting point and better heat resistance. This means that PP plastic retains its shape and stability at high temperatures. In addition, PP plastic has good chemical resistance, insulation, and low water absorption. Therefore, PP plastics are widely used in automobiles, electronics, medical devices and other fields.
So, which plastic material is safer? It mainly depends on its use and environment. If you need a food packaging container, PE plastic is a good choice because of its non-toxic, tasteless and good low temperature resistance. However, if you need a container for high-temperature environments, such as cooking utensils or car parts, PP plastic is more suitable because it has a higher melting point and better heat resistance.
In general, PE and PP plastics have their own advantages, and the choice of material mainly depends on the specific application scenario and needs. By understanding their properties, we can better choose and use plastic products to ensure the safety and health of our lives. Hopefully, this article will help you better understand these two common plastic materials and make more informed choices in your daily life.
