Plastic cup PC and PP material difference.

Material characteristics:

• PC RESIN  is a thermoplastic with excellent properties. Its excellent light transmission performance, known as "transparent metal", can be comparable to glass in transparency. In addition, PC plastics also have good flame retardancy, oxidation resistance, heat resistance and impact resistance. These characteristics make PC plastics widely used in many fields.

• PP RESIN is another common thermoplastic. It has the characteristics of light weight, high density, strong chemical resistance, high temperature resistance and good toughness. The cost of PP plastic is relatively low and the processing performance is excellent, so it has a wide range of applications in daily life.

Advantages of PC and PP

Advantages of PC

• Good heat resistance: PC plastic cups can withstand high temperatures and are not easy to deform or release harmful substances.

• High transparency: PC material plastic cups usually have high transparency, you can clearly see the items inside the cup.

• High hardness: PC plastic cup has a high hardness, not easy to scratch or deformation.

Advantages of PP

• Light and easy to carry: PP plastic cups are relatively light and easy to carry, suitable for outdoor activities or travel.

• Cheap price: PP plastic cup price is relatively low, cost-effective.

• Good low temperature resistance: PP plastic cups can withstand lower temperatures and are not easy to break.

PP and PC material difference

Appearance: pp is translucent, pc is transparent.

Application: pp material is often used to make water cups, beverage bottles and fresh-keeping boxes and other products, while pc material is often used to make water cups, baby bottles and soy milk machine cup bodies and other products.

Performance: pp material has good wear resistance but not resistance, pc material has strong impact resistance but poor wear resistance.

Aging: pp material is easy to age and become brittle and deformed, and pc bottles may appear scratches and yellowing after long-term use.

In general, there are obvious differences between pp and pc materials in terms of appearance, application, performance and aging. When choosing which material to use, it should be considered according to the specific needs and application scenarios. For example, for products such as baby bottles and water cups that need impact resistance, pc material is a better choice; For products such as crisper boxes and juice bottles that need to be wear-resistant, pp material is more suitable
