Recently, ** trading friends are always asking what some chemicals are for, because they are all industrial products of the chemical chain, the name is also very similar, today I will focus on the introduction of several varieties of pe, pp, pvc Chinese names are polyethylene, polypropylene and polyvinyl chloride, they also have a general name: plastic.
However, although the three plastics are different, the direct raw materials of PE and PP are ethylene and propylene, which are the largest downstream products of methanol, so the ultimate source of PE and PP is natural gas, coal and **.
From the downstream point of view, PE and PP are very substitutive, and the trend of the two is basically the same, but there are still some subtle differences in use. PE has high injury strength, and its largest consumer area is film, such as packaging film, thick film, etc. PP is stronger than PE and is the lightest general-purpose plastic, which is used in daily necessities such as basins, barrels, powder, and bumpers. As for PVC, it can be seen from the name that the raw materials are chlorine and ethylene, so it is essentially affected by oil and coal prices.
The consumption of PVC in China can be divided into two main parts. One part is soft products based on wires and cables and various hoses, and the other part is hard products represented by doors and windows and various profiles. Therefore, the demand of the PVC industry is also closely related to the real estate market. In terms of production capacity, the production capacity of PE and PP is more evenly distributed, and the production of PVC is mainly concentrated in the northwest region, and understanding the production capacity status of these regions is also very important for the investment of these three varieties.
The above is the relationship use of PE, PP, PVC, I hope it will help you in your transaction. Knowledge
