The key properties of PVC are that it is abrasion
resistance, and light weight, its good mechanical strength and
toughness are key technical advantages for its use in building and
construction applications.
PVC can be cut, shaped, welded and joined easily in a variety of
styles. It is also durable and is resistant to weathering,
chemical rotting, corrosion, shock and abrasion. It is
suitable for different long-life and outdoor products.
In fact, medium and long-term applications account for some 85%
of PVC production in the building and construction sector. For
example, it is estimated that more than 75% of PVC pipes will have a
lifetime in excess of 40 years with potential in-service lives of up
to 100 years. In other applications such as window profiles
and cable insulation, studies indicate that over 60% of them will
have working lives of more than 40 years.
Cost-Effective
PVC has been a popular material for construction applications for
decades due to its physical and technical properties, which
provide excellent cost-performance advantages. As a material
it is very competitive in terms of price, this value is also
enhanced by the properties such as its durability, life-span and low
maintenance.
Environmental Impact
In lifecycle analyses and independent studies, PVC's
environmental impact has been found to be favourable when compared
with other manufactured materials used for construction. It is
comparatively low in its energy and resource use during production,
as well as in conversion to finished products.
As a thermoplastic, PVC can be recycled, after it has been sorted
into a single material stream and can also play its part in mixed
plastics recycling. Facilities exist so that construction
materials such as pipes, window profiles and flooring can be
recycled at the end of their useful lives.
Additional recycling facilities for waste PVC construction
materials are being developed across Europe. At the end of a
product's useful life, if not recycled, it can be safely incinerated
or deposited in landfill. good thermal insulation of windows
and cladding helps to increase the energy efficiency of buildings.
Safe
Material
PVC is non-toxic. It is a safe material and a socially
valuable resource that has been used for more than half a century.
It is also the world's most researched and thoroughly tested
plastic. It meets all international standards for safety and
health for both the products and applications for which it is used.
Fire
Resistant
PVC is inherently difficult to ignite and stops burning once the
source of heat is removed. Compared to its common plastic
alternatives, PVC performs better in terms of lower combustibility,
flammability, flame propagation and heat release. Newly
developed PVC formulations (FR-PVC) have significant advantages in
terms of lower acid emissions, smoke generation and enhanced fire
resistance.
