EPS Foam (Expanded Polystyrene)

Expanded Polystyrene foam offers a broad range of physical properties to allow packaging designers to meet the challenges of protection and distribution. These properties, in combination with appropriate engineering design considerations, provide the design flexibility required to create truly cost effective protective packaging

This is an economical packaging foam that is available in densities ranging from 1# to 3# and is easily formed by cutting, hot wiring, molding and routing.

 

Typical Properties of EPS Molded Packaging (70F Test Temperature)

Density (pcf) Stress @ 10% Compression (psi) Flexural Strength (psi) Tensile Strength (psi) Shear Strength (psi)
1.0 13 29 31 31
1.5 24 43 51 53
2.0 30 58 62 70
2.5 42 75 74 92

3.3 67 105 98 140
4.0 80 125 108 175

Note: Values based on ASTM short-term, laboratory-load conditions. Both temperature and time period of loading may affect end-point values.

 

XPS FOAM (extruded polystyrene)

This is an extruded polystyrene product which has Exceptional moisture resistance, insulating efficiency and a variety of compressive strengths, combined with air infiltration reduction and labor savings make XPS insulation a suitable – even preferable – insulating material for use in commercial, industrial and residential structures, as well as for critical civil engineering uses.

This foam is produced by Dow Chemical and is available in a wide range of densities, sizes, and colors. PLEASE CALL FOR AVAILIBILTY.
