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
