Brief introduction of LDPE plastic raw materials:
LDPE plastic Chinese name: Low density polyethylene or high pressure polyethylene, English name is Low density polyethylene, its relative density is 0.910-0.925g / cm3, it is a white resin with a waxy feel, and its structure is non-linear The molecular weight is generally 100,000-500,000. The traditional low-density polyethylene is made by using polymer-grade ethylene with oxygen or peroxide as the initiator and performing free-radical polymerization at high temperature and pressure.
(B) the performance characteristics of LDPE plastic raw materials:
LDPE resin is white wax-like particles or powder. It has lower density, lower crystallinity and softening point, better softness, elongation, electrical insulation, transparency, and higher impact properties. . & # 160; & # 160; & # 160; & # 160; & # 160;
(Three) the use of LDPE plastic raw materials:
LDPE plastic raw materials are mainly used to produce the following products:
(1) Packaging films, agricultural films, architectural films, such as food packaging such as candy, vegetables, frozen products, lining films, shrink packaging films, flexible packaging films, and heavy packaging films.
(2) Low-density polyethylene injection molded products, such as: small containers, lids, daily necessities, toys, flower materials, microfiber synthetic leather, barriers, etc.
(3) Surface coating and coating, such as: paper, cardboard, steel pipe, aluminum foil and plastic film.
(4) Blow-molded containers, extruded sheets, sheets, pipes. Foam products. Rotomolded products, such as chemical containers and storage tanks.
