The basic concept
of 1. polypropylene
polypropylene (Polypropylene,PP) is a synthetic polymer obtained by polymerization of propylene monomer, the chemical formula is CH2 = CH-CH3. Compared with other synthetic polymers, polypropylene is characterized by its small molecular weight, so its physical properties are relatively low. Polypropylene is usually white or colorless crystals with high heat resistance, cold resistance and corrosion resistance, so it has been widely used in industry, agriculture and life.

2. Polypropylene Application

1, Industrial Field

Polypropylene has a wide range of applications in the industrial field, mainly including:

(1) Industrial packaging: plastic bags made of polypropylene, plastic films and other products are widely used in food, medicine, chemical and other fields of packaging, with good sealing and preservation.

(2) Plastic products: Plastic barrels, plastic trays, toys and other products made of polypropylene are widely used in various industrial fields.

(3) Textiles: Polypropylene fiber is one of the most important artificial fibers, used to make socks, gloves, T-shirts and other fabrics.

2.

in the agricultural field The application of polypropylene in the agricultural field mainly includes:

(1) Agricultural film: Polypropylene packaging film is widely used in agricultural production as an agricultural film, which can improve the yield and quality of crops and prevent rainwater from soaking.

(2) Greenhouse: Greenhouse panels made of polypropylene material are widely used in agricultural cultivation, which can maintain the heat contained in the heating process and provide suitable environmental conditions.

3.

in the field of daily life Polypropylene is still widely used in daily life, mainly including:

(1) Household goods: bowls, pots, bottles, chairs and other household goods made of polypropylene are widely used in modern families.

(2) Toys: Polypropylene is used as the main plastic raw material and is widely used in the production of children's toys.

(3) Medical supplies: Polypropylene infusion bags, surgical instruments and other medical supplies are widely used in hospitals and clinics. Summary of

3.

Polypropylene as a synthetic polymer has played an important role in industry, agriculture and daily life. It has many characteristics, such as high temperature resistance, corrosion resistance, etc., so that it has a wide range of applications in various fields. Knowing the properties and application range of polypropylene can help us better understand this chemical composition that is closely related to us, so as to make better use of its various wonderful uses.
