The importance of black masterbatch in agricultural film
The agricultural film is also called mulch film, also called plastic film, also called agricultural mulch film. The main component is polyethylene, which is used to cover farmland to improve the ground temperature, maintain soil moisture, promote seed germination and rapid growth of seedlings; The role of weed growth. The raw material of agricultural film is usually polyethylene (polyethylene, PE for short) is a thermoplastic resin obtained by polymerization of ethylene. Industrially, copolymers of ethylene and a small amount of an α-olefin are also included. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and is resistant to most acid and alkali corrosion. It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation properties. The requirements of agricultural film are: moisturizing, warming, non-toxic, non-polluting, strong aging resistance, and so on.
