Is your mug made of pc or pp?

From the material introduction, composition, advantages and disadvantages, performance, safety and other dimensions, comparative analysis of two common water cup material: pc and pp. To help you choose a more healthy and more practical water cup.

First, the material introduction:

PP and PC material is a modern widely used two engineering plastics. pp material, known as polypropylene, with moderate hardness, good molding, corrosion resistance, abrasion resistance, etc., widely used in the manufacture of household, medical and food packaging and other products. pp material is environmentally friendly and healthy, non-toxic and harmless, relatively low cost. However, its high temperature resistance is poor, the scope of application is relatively narrow.

PC material, all known as polycarbonate, has excellent transparency, impact resistance, high temperature resistance, high strength, good toughness, widely used in the manufacture of automobiles, construction, optics and electronics and other fields of products.

Second, the composition:

PP material, is a thermoplastic resin with polypropylene as the main component. Polypropylene is made of propylene monomer polymerization occurs under the action of a catalyst, its main components are carbon and hydrogen compounds, does not contain other heavy metal elements, so it has the advantages of environmental protection, health and so on. After adding a small amount of suitable plasticizers, stabilizers and other additives, PP material has excellent properties, such as higher hardness, good toughness, corrosion resistance, not easy to deform. In contrast to PC material, it is an amorphous thermoplastic resin with polycarbonate as the main component. Polycarbonate is mainly polymerized from monomers such as dibasic carbonate and phthalic anhydride. The elements involved in its composition include carbon, hydrogen, oxygen, etc. It is non-toxic, but harmful substances such as benzene may be released during processing.

Third, the advantages and disadvantages:

PP material compared to pc material, the advantages of relatively low cost, environmental health, non-toxic, harmless, moderate hardness, good molding, corrosion resistance, wear resistance and other characteristics, while the advantages of PC material is that it has excellent transparency, high strength, high impact resistance, excellent high temperature resistance, etc. PP material compared to pc material, pp material is less resistant to high temperatures, and the scope of application is relatively small. But the cost of PC material is relatively high, poor corrosion resistance, in the process may also release harmful substances.

Comprehensive view of the PP material is suitable for some of the requirements of environmental health occasions; and PC material is suitable for some of the requirements of high transparency, impact resistance in the field.

Fourth, performance:

PP material, also known as polypropylene material, has a light weight, impact resistance, high temperature resistance, not easy to deform, moisture-proof, waterproof, acid and alkali resistance, corrosion resistance and other characteristics, is widely used in automobiles, electrical appliances, plastic boxes and other fields. It has good plasticity and mechanical properties, in the manufacturing process is easy to process molding, made of high precision, high strength, long life of plastic products.PP material can be used for food packaging, medical equipment, toys and other products, and can be recycled to achieve the purpose of environmental protection. PC material is a polycarbonate material with the advantages of high strength, high toughness, strong texture, high transparency, and also has the characteristics of UV resistance and impact resistance, high temperature resistance, etc. It is widely used in the field of electronics, automotive, medical equipment and so on. It also has the properties of fire resistance, corrosion resistance, heat resistance, solvent resistance and abrasion resistance, and can be used in harsh environments for a long time. In addition, PC material is also good weather resistance, electrical insulation and molding, so it is widely used in the manufacture of high-end products.

Fifth, the degree of safety:

PP material has a high degree of chemical stability, will not produce odor and harmful substances due to chemical contact, can be directly used as food packaging materials. At the same time, PP material also has anti-fog, anti-dripping, anti-oxidation and other characteristics, to ensure the quality of food and hygiene standards. pc material is also a very safe material. pc material has a high degree of thermal stability and excellent mechanical properties, widely used in the manufacture of high-end electronic products and medical devices. As a food contact material, PC material has good transparency and heat resistance, and is suitable for making high temperature ovenware, stainless steel pots and pans, microwave ovens and so on.
