  • 2. • 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 containers. • Polystyrene is also co polymerized or blended with other polymers lending hardness and rigidity to a number of important plastic and rubber products. INTRODUCTION
  • 3. • Polystyrene is a synthetic aromatic polymer made from the monomer styrene. • It can be solid or foam. • Low density. • Good thermic insulant. • Flammability. • Poor barrier to oxygen and water vapour. • Has relatively low melting point. PROPERTIES
  • 4. • As a thermoplastic polymer, polystyrene is in a solid state at room temperature but it flows if heated about 100o C. • This temperature behaviour is exploited for extrusion and also for molding and vacuum forming since it can be cast into molds with fine details

  • 7. 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 APPLICATION:
  • 8. • 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 as reinforcement. • With the interlocking polystyrene block system and exceptionally strong yet insulated building can be constructed faster than possible with normal brick and mortar ADVANTAGES • Sound emission from within the building is low. • Mold and insect infestation is eliminated. • Cheaper building methods. POLYSTYRENE BLOCKS
  • 9. • 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. Types: • Foam control • Polar below grade • Polar fold • Radiant floor panels BELOWGRADE & UNDERSLAB INSULATION
  • 10. • 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. Benefits: • Energy efficient • Less cost • Superior moisture resistant • Easy to handle and install CAVITY WALL INSULATION
  • 11. • It is a cost effective durable and energy efficiency solution for insulation applications. • 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. ADVANTAGES: • Light weight . • High strength. • Excellent adhesion to concrete. CONCRETE APPLICATIONS
  • 12. • 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. Benefits: • 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. ROOF INSULATION
  • 13. • 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 dioxide. • 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.
