PP powder is a fine powder material made of polypropylene through processing, grinding and screening. PP powder has the advantages of uniform particles and easy processing and molding, and can be used to make PP storage tanks with smooth surface, high strength, corrosion resistance and high temperature resistance. However, the production cost of PP powder is high, which requires high production technology and equipment, so the price is relatively high.
PP pellet is a granular material made of polypropylene through processing, melting and extrusion. The advantages of PP pellets are low production cost, easy processing and molding, and can be used to make PP storage tanks with smooth surface, high strength, corrosion resistance and high temperature resistance. However, the particle size of PP is uneven, which is easy to produce bubbles and defects. It needs the support of processing technology and equipment to ensure product quality.
Therefore, the selection of raw materials for PP storage tanks should be based on the actual situation and product requirements of manufacturers to ensure the balance between product quality and production cost.
