High-density polyethylene (HDPE) is a polyethylene
thermoplastic made from petroleum. It takes 1.*5 kilograms of
petroleum (in terms of energy and raw materials) to make one
kilogram of HDPE. HDPE is commonly recycled, and has the number "2"
as its recycling symbol. In ***7, the global HDPE market reached a
volume of more than *0 million tons.
HDPE is also used for cell liners in subtitle D sanitary
landfills, wherein large sheets of HDPE are either extrusion or
wedge welded to form a homogeneous chemical-resistant barrier, with
the intention of preventing the pollution of soil and groundwater
by the liquid constituents of solid waste.
One of the largest uses for HDPE is wood plastic composites
and composite wood, with recycled polymers leading the way.
HDPE is also widely used in the pyrotechnics trade. HDPE
mortars are preferred to steel or PVC tubes because they are more
durable and more importantly they are much safer compared to steel
or PVC. If a shell or salute were to malfunction (flowerpot) in the
mortar, HDPE tends to rip or tear instead of shattering and
becoming shrapnel like PVC, which can kill or maim onlookers. PVC
and steel are particularly prone to this and their use is avoided
where possible.
Milk bottles and other hollow goods manufactured through blow
molding are the most important application area for HDPE - More
than 8 million tons, or nearly one third of worldwide production,
was applied here. Above all, China, where beverage bottles made
from HDPE were first imported in ***5, is a growing market for
rigid HDPE packaging, as a result of its improving standard of
living. In India and other highly populated, emerging nations,
infrastructure expansion includes the deployment of pipes and cable
insulation made from HDPE.The material has benefited from
discussions about possible health and environmental problems caused
by PVC and Polycarbonate associated Bisphenol A, as well as, its
advantages over glass, metal and cardboard.
Mainly used for the production of high toughness of the
