Heavy Duty Polypropylene White Plastic Sheet OEM For Construction

The cost of PP sheets (polypropylene sheets) is closely related to raw material prices, production processes, and specifications. In terms of raw materials, polypropylene resin, as the basic raw material, has a relatively stable price and is lower than that of engineering plastics such as ABS and PVC. The cost per ton is usually 30%-50% lower than that of ABS. In the production process, mature technologies like extrusion and calendering result in low energy consumption, further controlling processing costs. Taking common 3-5mm thick sheets as an example, the unit price per square meter is about 15-40 RMB, which is much lower than that of stainless steel plates (100-300 RMB/㎡) and FRP plates (80-150 RMB/㎡), and only slightly higher than that of ordinary PVC plates (10-30 RMB/㎡), showing a significant cost advantage.​

In terms of applications, PP sheets, with the combination of low cost and multiple properties, cover many fields: in the chemical industry, they are used to make storage tanks and pickling tanks, replacing expensive stainless steel equipment; in the construction industry, they serve as waterproof liners and temporary partitions to reduce construction costs; in agriculture, they are used as linings for irrigation channels and breeding ponds, taking into account durability and economy; in household scenarios, they are used to make storage boxes and waterproof baffles, with a cost performance far exceeding that of wooden or metal products. Its cost-effectiveness advantage lies in the balance between "low cost and adaptability", and this advantage is prominent in multi-dimensional scenarios.

The service life of PP sheets is not a fixed value; it is comprehensively affected by the usage environment, application scenarios, and the inherent characteristics of the material, typically ranging from 5 to 15 years.​

In indoor dry and non-corrosive environments, such as home storage and office partitions, PP sheets can maintain stable performance, with a service life of 10 to 15 years. In such cases, they mainly face a slight attenuation of long-term mechanical properties, such as a certain degree of aging leading to reduced toughness, but this basically does not affect normal use.​
