What aspects can PP substitute for PVC?

1. Color difference:

PP material cannot be made transparent, and the commonly used colors are primary color (the natural color of PP material), beige gray, porcelain white, etc. PVC is rich in color, generally dark gray, light gray, beige, ivory, transparent, etc.

2. Weight difference:

PP board is less dense than PVC board, and PVC has a higher density, so PVC is heavier.

3. Acid and alkali resistance:

The acid and alkali resistance of PVC is better than that of PP board, but the texture is brittle and hard, resistant to ultraviolet radiation, can withstand climate change for a long time, is not flammable, and has light toxicity. However, PP board is not UV-resistant, and it will change color when exposed to sunlight for a long time.

4. Temperature difference

Domestic brands: The temperature range of PP is about 0 to 80 degrees Celsius, and the range of PVC is 0 to 60 degrees Celsius.

Imported brands: The temperature range of PP is about 0 to 100 degrees Celsius, and the temperature range of PVC is -40 to 95 degrees Celsius.

From the perspective of the downstream consumption structure of PVC, at present, pipes and fittings are the main application of PVC, accounting for about 32% of its downstream applications, followed by building materials, accounting for about 24% of downstream applications, and cables accounting for 11% of downstream applications; with the price of PVC Continuing to rise, PP may form a partial replacement for PVC in the fields of pipe fittings, plates, cable protective sleeves, etc.; but since PP/PE/PVC currently perform their respective functions, most of the fields that can be replaced have been replaced, and the specific replacement situation will be later. It is also necessary to keep an eye on downstream production.
