The difference between PP sheet and PVC sheet

When customers buy boards, they usually think of PP board and PVC board, but what is the difference between the two boards? Lida Plastics will summarize the following points and share with you, hoping to provide reference information for those in need.

First of all, PP board and PVC board are chemical polymers, PP is polypropylene, and PVC is polyvinyl chloride.

1. Color difference:

PP materials cannot be made transparent. Common colors are primary colors (natural color of PP materials), beige gray, porcelain white, milky white, etc. PVC is richer in color, generally gray, light gray, white, yellow and white, transparent, etc.

2. Weight difference:

PP board has a lower density 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 more brittle and hard, resistant to ultraviolet radiation, can withstand climate change for a long time, and is not flammable.

4. Temperature difference:

 A. Domestically produced; PP has a temperature range of 0 to 80 degrees Celsius, PVC has a temperature range of 0 to 60 degrees Celsius, and CPVC material has a temperature range of -40 to 95 degrees Celsius. B. Imported brands: PP's temperature range is about 0 to 100 degrees Celsius, and PVC's temperature range is -40 to 95 degrees Celsius.

5. The price difference:

 Compared with the price of PVC, PP is cheaper and PVC has a higher density, so PVC is heavier and more expensive.

6. Application scope:

 A. PP board is mainly used in acid and alkali resistant equipment, environmental protection equipment, waste water, exhaust gas discharge equipment, washing towers, clean rooms, semiconductor factories and related industrial equipment. Among them, PP thick plates are widely used in stamping plates and mattresses. Board etc. B. PVC board is mainly used in building materials, packaging, medicine and many other industries. Such as construction, electroplating equipment, acid and alkali resistant equipment, industrial sewage equipment, chemical industry, etc.
