EEI Expanded Polystyrene
is rigid and light - weighted. By controlling the
density of expanding beads during the manufacturing process, EEI can custom
produce insulation materials according to the specific requirements of
customers applications. EEI production of Expanded Polystyrene boards and
injection molded boards are in conformity with the British Standard
specification BS 3837: 1977 for expanded Polystyrene boards, DIN and ASTM
(American Society for Testing and Materials).
Type N (Normal)
It consists of 100% of closed cell polystyrene expandable
Type A (Fire Retardant)
It is similar to Type N, but meets additional
requirements for the extent of burn when tested with the method given by virtue
of BS 4735. This requirement is met by the incorporation of flame retardant
additives and other appropriate modifications .
Thickness and Tolerances
Thickness can be cut as required, from 8 mm up to 1120 mm. On specified
thickness, length, and width, tolerance will be + - 2 mm.
The large molded blocks are hot wire cut on flat lines at any desired
thickness, width, and length. In addition, EEI CAD / CAM capabilities
provide its customers with an infinite variety of standard, customs, and redius
products. Cut boards are boards cut from a block molded from expanded
beads, which could be fine, very fine, or coarse grain. Used raw materials
could be of general purpose (type N material) or fire retardant category (type
Molded boards are boards of injection molded from expanded beads, that has
surface skin on all sides and molded edges.
