Polyethylene and Open Cell Polyurethane foams are being used more and more in applications for ESD (Electro Static Discharge) the foam is used in the packaging of static sensitive electronics devices.
To ensure the integrity of your products Apollo Foam have a range of products which are ESD compliant for electronics packaging devices, assembles and electronics equipment.
Electro Static Discharge is most commonly created by the contact and separation of two materials. Critical devices and assemblies are susceptible to these static charges and the smaller the circuitry is the more vulnerable it is. The materials of choice in this industry are Conductive, Static Dissipative, and Anti Static.
The difference is the speed the static charge travels through the material when it makes contact with a conductive source.
Conductive foams have a volume resistivity of less than 104Ω.
Static Dissipative grade foams offer a slower more controlled transfer of static charge with a resistivity in the range of 104Ω to 1011Ω.
Anti Static Polyethylene foam which is generally non-cross linked and pink in colour have a surface resistivity of 1010Ω to 1012Ω.
Apollo Foam offers the following grades from stock:
The LD stands for low density, the number denotes the density of the material per cubic metre, and SD stating the material is Static Dissipative.
The LD standing for low density, the number denotes the density per cubic metre, and CN denoting the conductive grade.
Then we have the hybrid grades:
The EV stands for Evazote, the number denotes the density per cubic metre, and CN stating the material is conductive.
Pink Anti Static Polyethylene foam is available in a sheet / extruded plank or as an extruded and laminated sheet. the clear visible differences being the laminations in the make up of the extruded and laminated. this is generally manufactured in 35kg per cubic material foam and available in two varying sheet sizes.
Sheet / Plank 600mm x 2750mm
Laminated sheet 1200mm x 2000mm
Both of which are available from stock.
Our polyethylene foams are converted to our customers’ individual requirements from split sheets, pressed foam fitments, waterjet and routed polyethylene foam components for all market sectors.
