What is the difference between PP board and PC board?

There are significant differences between PP board and PC board in multiple aspects, and the following are some main differences:

1. Physical properties:

(1) PC board is a high-strength, high transparency plastic with excellent mechanical properties, including impact resistance, toughness, and heat resistance. It has a wide temperature range and can maintain stable performance in various environments.

(2) PP board is a lightweight, chemical resistant, and impact resistant plastic with good low-temperature toughness and some heat resistance, but it is usually not as strong as PC. Its operating temperature range is approximately -20 ℃ to 100 ℃.

2. Chemical stability:

(1) PC boards have good resistance to many chemicals (including acids, bases, and salts), but stress cracking may occur when exposed to certain solvents (such as alcohols) for a long time.

(2) PP board has good resistance to most chemicals (except strong oxidants and certain solvents) and is not easily subjected to stress cracking.

3. Transparency:

(1) PC boards have the characteristic of high transparency, which can produce very clear products such as eyeglass lenses and mobile phone screens.

(2) PP board has relatively low transparency and is usually used in applications that do not require high transparency.

4. Environmental friendliness:

(1) PC boards are not easily degradable, causing certain pressure on the environment.

(2) PP board performs relatively well in terms of environmental friendliness, but its impact still needs to be evaluated based on specific application scenarios.

5. Processing performance:

(1) PC boards can be formed through various processing methods such as injection molding, extrusion, and blow molding, but due to their high melting point and viscosity, the processing may require higher temperatures and pressures.

(2) PP board has high mechanical strength, is easy to cut into various shapes, and can also be processed such as molding and welding, making it convenient to use.

6. Weather resistance:

(1) PP board has good characteristics such as aging resistance, UV radiation resistance, and climate change resistance. It can be used for a long time under bright sunlight and is not easily yellowed, brittle, or aged.

(2) PC boards also have excellent weather resistance, which can maintain their performance and appearance for a long time.

In summary, there are significant differences between PP board and PC board in terms of physical properties, chemical stability, transparency, environmental friendliness, processing performance, and weather resistance. The choice of sheet metal depends on the specific application scenario and requirements. In practical applications, it is recommended to comprehensively consider factors such as specific usage conditions, performance requirements, and cost budget to select the appropriate type of sheet metal.
