Low-density polyethylene (LDPE)

1. Products properties

Low-density polyethylene (LDPE)is a synthetic resin using a

high pressure process via free radical polymerization of ethylene

and is therefore also called “high-pressure polyethylene”. Since

its molecular chain has many long and short branches, LDPE is

less crystalline than high-density polyethylene (HDPE) and its

density is lower. It features light, flexible, good freezing resistance

and impact resistance. LDPE is chemically stable. It has good

resistance to acids (except strongly oxidizing acids), alkali, salt,

excellent electrical insulation properties. Its vapor penetration rate

is low. LDPE has high fluidity and good processability. It is suitable

for being used in all types of thermoplastic processing processes,

such as injection molding, extrusion molding, blow molding,

rotomolding, coating, foaming, thermoforming, hot-jet welding and

thermal welding.

2. Application:

LDPE is principally used for making films. It is widely used in

the production of agricultural film (mulching film and shed film),

packaging film (for use in packing candies, vegetables and frozen

food), blown film for packaging liquid (for use in packaging milk,

soy sauce, juice, bean curds and soy milk), heavy-duty packaging

bags, shrinkage packaging film, elastic film, lining film, buildinguse

film, general-purpose industrial packaging film and food

bags. LDPE is also widely used in the production of wire & cable

insulation sheath. Cross-linked LDPE is the main material used in

the insulation layer of high-voltage cables. LDPE is also used in the

production of injection-molded products (such as artificial flowers,

medical instruments, medicine and food packaging material) and

extrusion-molded tubes, plates, wire & cable coatings and profiled

plastic products. LDPE is also used for making blow-molded hollow

products such as containers for holding food, medicine, cosmetics

and chemical products, and tanks.

3. Storage:

The resin is packaged in internally film-coated polypropylene

woven bags, brown paper bags or laminated polyethylene film

bags. The net weight is *5Kg/bag.

The resin should be stored in a drafty, dry warehouse and away

from fire and direct sunlight. It should not be piled up in the open

air. During transportation, the material should not be exposed to

strong sunlight or rain and should not be transported together with

sand, soil, scrap metal, coal or glass. Transportation together with

toxic, corrosive and flammable substance is strictly prohibited
