EPS Sheets

EPS sheets are used as concrete curing application. These sheets are used as insulation medium when concrete is directly exposed to sunlight or windy weather. KPIC is supplying from 50mm thick standard size sheets for such applications. Standard Size: 2000×1000 mm or any non-standard size can be cut and supplied. Density: Normally from 18-23 Kgs/m3 sheets are recommended.

Expanded Polystyrene cut strips are used as expansion joint fills. A general concrete surface has a tendency to shrink or expand according to the atmospheric temperature. It expands in summer and shrinks in winter. To protect the concrete surface and avoid any cracks on the surface, EPS strips are used as expansion joint fills while casting. EPS strips allow the concrete to expand or shrink without any cracks or damage on the surface. These strips can also be used in the roads, bridge slabs, and precast elements. Standard Size: 2000x200x15- 20mm. EPS high-density strips are recommended to fill the joints. Density: 20-25 Kg/m3.

Our products are free from CFC (Freon Gas) and with testing method of ASTM C 578-01.

Expandable Polystyrene:

EPS sheets which can be produced in density rang- es between 18 kg/m3 – 23 kg/m3 are suitable for high quality block molding and shape molding with a section thickness of 15 mm to 50 mm, ensuring rapid molding with its short cycle time. EPS sheets in general is used for cases and packaging product suitable for food contact, insulation application which is not requiring fire classification, in industrial applications inside proton brick with impact absorber and for light concrete applications and insulation of concrete block

Typical Properties:

  • Bead Size Range (mm): 0,4 – 0,7
  • Sieve Analysis: 0.4 mm – 0.85 mm min %99
  • Bulk Density : ≈ 615 kg/m3

Special Features of EPS Sheets

    FEATURES

    • Low Moisture Absorption: Moisture absorption rates decrease as density increases, but are still minimal. Material thickness can increase moisture absorption performance.
    • Inert: Experiences no physical or chemical breakdown over time. No nutrient value to animals, insects and organisms. No nutrient value to bacterial growth including mold.
    • No Leachates: It will not contaminate the surrounding environment.

    DESIGN CAUTIONS

    • Flammability: EPS is combustible and should not be exposed to flame or other ignition sources. EPS should be covered with a thermal barrier or otherwise installed in accordance with applicable building code requirements.
    • Solvent Damage: EPS is susceptible to damage by petroleum based solvents and their vapors. Protect with vapor barrier covering and/or use compatible adhesives when applicable.
    • Ultraviolet Damage: Extended exposure to sunlight causes minor discoloration and surface dusting. Shield from direct sunlight for prolonged periods of time.
