| Polystyrene in expanded into a number of
densities and forms for different uses: |
| • Low Density |
Light general
packaging where void filling is more important than
durability and finished quality. |
| • Standard
Density |
The most commonly
used grade for most general applications such as
packaging, insulation and display.
It presents a reasonably durable product with an
acceptable finish. |
| • Medium Density |
Used when the
standard grade may not offer enough strength in the
material to withstand the weight of the object to be
protected or any impact damage it might suffer. |
| • Higher
Densities |
These are used
for delicate items or where the weight of the object
requires a more robust material. |
| • Bead |
Polystyrene bead
is free expanded and achieves a diameter of
approximately 6mm |
| • Styrofoam |
This is a variation of polystyrene but with differing
properties, used mainly for insulation and model making.
It can be profiled as polystyrene can be, but via
different methods, to create more complex and detailed
items. |
| Fire Retardant
(FRA) polystyrene can be sourced for the lower grades
within 5-7 days and for higher grades 2-3 weeks (STC) |
