• Polystyrene is a hard, stiff, brilliantly transparent synthetic resin produced
by the polymerization of styrene.
• It is widely employed in the food service industries as rigid trays and
• Polystyrene is also co polymerized or blended with other polymers
lending hardness and rigidity to a number of important plastic and rubber
• Polystyrene is a synthetic aromatic polymer made from the monomer styrene.
• It can be solid or foam.
• Low density.
• Good thermic insulant.
• Poor barrier to oxygen and water vapour.
• Has relatively low melting point.
• As a thermoplastic polymer, polystyrene is in a solid
state at room temperature but it flows if heated about
• This temperature behaviour is exploited for extrusion
and also for molding and vacuum forming since it can
be cast into molds with fine details
• Sheet or molded polystyrene
• Expanded polystyrene
• Extruded polystyrene foam
• BUILDING INDUSTRY
• INSULANT CONTAINER
• FINISHING PRODUCTS
• GAMES MODELLING & DECORATION
• TECHNICAL PRODUCTS
• TRAFFIC AND STORE RESOURCES
• PACKING MATERIALS

AREA OF EXPLOITATION OF POLYSTYRENE
Mainly used for insulation.
Types of insulations:
• Below grade insulation
• Cavity wall insulation
• Concrete applications
• Exterior insulation and finish systems(EIFS)
• Radiant floor insulation
• Roof insulation
• Structural insulated panels
• They are used in construction as permanent insulation in buildings
• The blocks are energy efficient and ensure optimal insulation
• The blocks are stacked and then the forms are filled with concrete.
• Once in place the blocks are used to give structure. As soon as the
concrete is casted in the blocks stability is gained, steel bars are provided
• With the interlocking polystyrene block system and exceptionally strong
yet insulated building can be constructed faster than possible with normal
brick and mortar
• Sound emission from within the building
• Mold and insect infestation is eliminated.
• Cheaper building methods.
• With upto 50 percent of a building’s total heat loss occurring at the
perimeter and the slab of the foundation, below grade insulation is
crucial to achieving energy efficiency.
• This insulation is a proven and effective method of conserving heat
energy in cold climates and air conditioning energy in warm climates.
• Foam control
• Polar below grade
• Polar fold
• Radiant floor panels
BELOWGRADE & UNDERSLAB INSULATION
• More than half of a building’s heat is lost through un insulated walls, rising
energy cause have made it crucial to properly insulate a building.
• This insulation creates a more comfortable living environment coz temperature
inside the building will not fluctuate due to changes in outside temperature.
• Stabilizing the temperature inside will reduce heating and cooling costs.
• Energy efficient
• Less cost
• Superior moisture resistant
• Easy to handle and install
CAVITY WALL INSULATION
• It is a cost effective durable and energy efficiency solution for insulation
• It is an ideal material to stop energy loss.
• For poured in place and precast concrete systems reduces the
requirement for concrete and overall weight.
• Light weight .
• High strength.
• Excellent adhesion to concrete.
• EPS insulation is reliable, cost effective
and compatible with major roofing materials and systems.
• It stands the test of time and its roof insulation
is proven performer in roofing applications.
• Has no thermal drift and does not use blowing
agents that diffuse out the insulation.
• It contains no CFC’s and formaldehyde and it
comes with a 50 year thermal warranty.
• Polystyrene has a negative impact on environment.
• These are produced using blowing agents that form bubbles and expand
the foam. Polystyrene is usually made with HFC which have global
warming potentials of approximately 1000-1300 times that of carbon
• Polystyrene discarded in the environment does not break down for
hundreds of years and takes up precious space in landfill.
• Easily blown by the wind ending up as litter in the environment where it
can harm animals and marine life.
• Animals can mistake polystyrene for food and it can be lethal to birds and
sea life that swallow it.
