Made of high-quality plastic, the size of the paper cup is mostly used for breeding and seedling raising. Black plastic nutrition has the functions of heat absorption during the day, heat preservation at night, and fertilizer retention. It has the function of retaining water during the drought season; it is easy to concentrate and cultivate with nutrient carp breeding and seedling.
Polyethylene has general mechanical properties, low tensile strength, poor creep resistance and good impact resistance. Polyethylene can be processed by blow molding, extrusion, injection molding, etc., and is widely used in the manufacture of films, hollow products, fibers and household groceries.
Used in the production of film for agricultural, food and industrial packaging, wire and cable coating and coating, synthetic paper, etc.; keep the storage sealed and stored in a cool, dry place, to ensure good ventilation or exhaust in the workplace.
It is a thermoplastic resin obtained by polymerizing ethylene.
Industrially, copolymers of ethylene and a small amount of an α-olefin are also included. Polyethylene is odorless, non-toxic, waxy, and has excellent low temperature resistance (minimum use temperature can reach -70~-100°C). It has good chemical stability, can resist most acid and alkali corrosion (not resistant to acids with oxidizing properties), is insoluble in common solvents at normal temperature, has low water absorption and excellent electrical insulation properties.
