PP (Polypropylene) is a thermoplastic polymer with the following characteristics and uses:
Characteristics:
Good chemical corrosion resistance: PP has good corrosion resistance to
ACID, alkali, salt and other chemical substances, and can work stably in high temperature, high pressure, and harsh environments. Therefore, PP is widely used in the production of corrosion-resistant containers, pipelines, etc.
Good UV resistance and antioxidant properties: PP has good UV resistance and antioxidant properties, and can be used outdoors for a long time without aging or yellowing. Therefore, PP is widely used in the production of outdoor products, building materials, etc.
Good thermal stability and mechanical properties: PP has good thermal stability, rigidity, and toughness. PP has a high melting point and can maintain stable performance at high temperatures, making it widely used in the production of high-temperature resistant components and structural components. Meanwhile, PP has good mechanical properties and high tensile and impact strength, making it suitable for producing high-strength products.
Low density and light weight: PP has a low density and a specific gravity of only 0.91-0.93, making it lightweight and easy to process. It is suitable for making lightweight products such as automobiles and airplanes. At the same time, the surface of PP is smooth and easy to cut, press, inject and other processing techniques.
The performance can be changed through additives: PP can change its performance by adding various fillers, plasticizers, antistatic agent, etc. to make it flame retardant, antistatic, antibacterial, and reinforcing. For example, adding glass fiber can enhance the rigidity and strength of PP, adding
Carbon Black can make PP have anti ultraviolet and anti electrostatic properties, and adding antioxidants can extend the service life of PP.
Application field:
Packaging industry: PP is widely used in the packaging industry, such as food packaging, cosmetics packaging, pharmaceutical packaging, etc. PP made plastic bags, boxes, bottles, etc. have excellent heat resistance, cold resistance, oil resistance, water resistance, and other properties, which can protect the quality and safety of packaged items.
Automotive industry: PP has excellent wear resistance, rigidity, toughness, and other properties, suitable for making components such as car casings, instrument panels, and seats. The automotive components made of PP have high durability and lightweight advantages, and are increasingly widely used in the automotive industry.
Medical equipment: PP has good chemical resistance, high transparency, and is suitable for making medical supplies, infusion bottles, etc. The medical devices made of PP have high hygiene and safety, and are widely used in the medical industry.
Household goods: Furniture, storage boxes, shoe boxes, etc. made of PP have the advantages of heat resistance, durability, and portability. PP produced household products are safe, environmentally friendly, and meet people's needs for home life.
Electronics industry: PP made battery boxes, cable sleeves, TV casings, etc. have good insulation performance and high temperature resistance
