LDPE Sheets
are thermoplastic sheets which are fabricated from monomer ethylene.
Free radical polymerization is used through a high pressure process
in manufacturing these sheets. At room temperatures these sheets are
non reactive except that swelling is caused by some solvents and
strong oxidizing agents. These sheets can withstand for a short time
95 degree centigrade and continuously can withstand 80 degree
centigrade. These sheets are fabricated with opaque or translucent
variations.
These LDPE Sheets are
quite tough and flexible but are breakable. These sheets have weaker
intermolecular forces because these consist of atoms which are more
branching. These sheets have higher resilience and lower tensile
strength. For the side branches these sheets contain molecules which
are less crystalline and less tightly packed. These sheets have lower
density and consist of chemical elements of hydrogen and carbon.
These LDPE Sheets have
excellent resistance to concentrated and dilute alcohols, acids,
esters and bases. These have good resistance to ketones, aldehydes
and vegetable oils. These have short term use or limited resistance
to aromatic hydrocarbons and aliphatic, oxidizing agents and mineral
oils. These sheets are not recommended to use and have poor
resistance with halogenated hydrocarbons.
These LDPE Sheets are
extensively used for fabricating different dispensing bottles,
containers, wash bottles, plastic bags, tubing, for several molded
laboratory equipment and for computer components. Mainly these sheets
are used for manufacturing plastic bags and the other items made from
these sheets include work surfaces with corrosion resistance, general
use containers and trays, parts which are used for machining and have
weld ability, pliable and very soft parts like snap on lids, parts
which serves well and require flexibility, six pack rings, plastic
wraps, playground slides, computer hardware slides like optical disc
drives, screen cards and hard disk drives. These sheets are used as
outer and water proof inner layer in milk and juice cartons which are
laminated with paperboard and with aluminum foil layer to provide
aseptic packaging.
LDPE Sheets are
of food grade substances which are very flexible and are used
worldwide successfully for the purpose of preservation of Natural
Resources. These sheets possess some unique properties which include
non toxic, inert material, weathering and ageing, critical friction
angle, thermal expansion having low co efficient, seam ability, weld
ability, conformability and deformability to soil, puncture
resistance and flexibility.
These sheets are
also used for the above properties in various applications of
construction and agricultural industries. Some of which include
linings of ponds, reservoirs, distributaries, canals, industrial
effluent plants, packaging, trenches, tunnels, in terrace gardens for
waterproofing, salt pans, sports stadiums, concrete bridges and
roads, at airport in runways and aprons, for covering instruments,
cement, chemicals, cotton, fertilizers and food grains and during
emergencies in natural calamities for the shelter houses.
These sheets are
easily available online. Persons interested can browse the official
websites of the manufacturers to directly avail from them.
