6 reasons to use GWP Conductive anti static foams
01: Pink Anti-Static Foam.
Full customisation of conductive packaging products through pink anti-static foams
Pink anti-static foam inserts boast a wealth of beneficial features, including offering high levels of ESD protection for any static sensitive device.
Besides this, pink anti-static foam inserts offer excellent levels of protection against impact, shock and vibration whilst items are in transit.
Suitable for computer chips, circuit boards and various other static sensitive devices, pink anti-static foam inserts are extremely cost effective, assisting in reducing damage costs.
What is pink anti-static foam?
Manufactured to include an Antistatic additive, these pink foams give a surface conductivity that will reduce over time.
Glycerol Mononstearate (GMS) is a commonly used additive (although other similar chemicals are also used), which is introduced during the extrusion phase of the material manufacture.
This additive will then slowly migrate to the edges of the foam before forming lines on the surface.
One end of the microscopic antistatic molecule protrudes from the material edge and draws in moisture from the ambient air to allow a conductive path for current to pass through.
This type of foam typically has a volume resistivity in the range of 1010 – 1012 ohms.cms and often has a surface resistivity that is higher still.
Due to the way in which the foam works, performance can be enhanced with increased atmospheric humidity.
Pink anti-Static foam is a polyurethane foam that is chemically enhanced with an anti-static agent (surfactant) and colored with a pink dye for identification. It will not generate static charge when it rubs against itself, and is usually used for single trip shipping.
A perfect enhancement for Corstat solutions
A large number of the stock boxes and packaging products you can source from GWP Conductive, such as transit packs, compak shippers and chip boxes, are all enhanced through the use of pink anti-static foam inserts.
Pink anti-static foam’s unique properties allow the foam to slowly dissipate electro-static charges that are potentially created by adjacent components, the component itself or even human handlers during the transit process.
Pink anti-static foam is also excellent for cushioning sensitive circuit boards, computer chips and other electronics from shock, impact and vibration.

02: Conductive Foam.
Conductive foam inserts and cushioning for ultimate protection
Conductive foam, available from GWP Conductive provides an ESD safe solution for handling and transporting any of your products that are sensitive to static charge.
Minimising the effects of electro static discharge on static sensitive electronic equipment, conductive foam offers an extremely reliable method for protecting items in transit.
Offering an entirely bespoke service, GWP will carefully design and manufacture your conductive foam inserts to suit any specific needs or requirements.
What is conductive foam?
Conductive foam is similar to standard packaging foams but with one crucial difference – the addition of carbon to the polymer mix during the manufacturing process to provide a high level of conductivity.
This allows any electric current to pass through the cell structure of the foam and away from the component.
Generally, the foam will have permanent conductive performance, meaning it is ideal for multi-trip packaging and in-plant handling applications. Its performance isn’t affected by atmospheric conditions.
This ESD safe material will typically have a surface resistivity of fewer than 104 ohms/sq. and a volume resistivity of fewer than 104 ohms/cms, which offers a quicker transfer of any static charge to a grounding source or adjacent conductive material.
Conductive foam is a polyethelyne foam filled with carbon (as are all black ESD foams), giving it its conductive properties and color. Conductive foam is designed for repeat use, and will act like a Faraday cage when an item is fully enclosed within it.
High performance yet cost effective conductive foams
At GWP Conductive, we provide your business with expertise in the creation of conductive foam inserts to work alongside our wide selection of conductive and ESD safe packaging, handling and transit products.
The conductive foams we use help to minimise the effects of electro static discharge on sensitive electronic equipment.

03: Static Dissipative Foam.
Static Dissipative foam inserts to offer exceptional ESD protection
Static dissipative foam offers a controlled and effective solution for protecting static sensitive devices whilst being transported or handled.
Ideal for use within various Corstat or Corriplast containers, static dissipative foam inserts can be designed and manufactured to provide calculated levels of cushioning performance for any application. Besides this, static dissipative foam controls transfer of static charges that may affect sensitive electronics or devices.
What is Static Dissipative Foam?
Static dissipative foams protect sensitive electronic equipment, circuit boards and PCBs through the use of impregnated carbon, allowing any static charges generated to dissipate through the foam material.
The nature of the foam ensures that its performance is not affected by atmospheric conditions and has no restrictive shelf life – making it ideal for multi-trip, handling and storage applications.
The static dissipative foam that we use at GWP Conductive will generally have a volume resistivity between 104 – 1011 ohms/cms or a surface resistivity in the ranges of 104 – 1011 ohms/sq. whilst this results in a slower transfer of the charge, it is more controlled.
Static Dissipative foam is a polyethelyne foam that is either black carbon-impregnated, or pink colored and enhanced with surfactants. It is the general choice of foam for reusable applications, unless you require the specific properties of conductive foam.
Static dissipative foam a superb choice for static sensitive protection
Alongside GWP’s conductive and anti-static foam packaging products, we can also supply inserts in a range of static dissipative foams.
Offering a slower but more controlled transfer of static charges that may affect sensitive electronics, this foam perfectly complements the vast majority of Corstat and Corriplast packaging and materials handling products.
We have a number of experienced, dedicated foam designers in-house with the ability to provide expert advice on the most appropriate material for a specific application.
This can even include the calculation of the exact levels of cushioning performance if an item is particularly sensitive to shock and impact. All of this is combined with a modern production facility, offering CNC routing, die and water jet cutting techniques.

06:Why GWP Conductive?
Genuine expertise in both static and foam performance
Anti static packaging is a very specialised discipline – in that not many regular packaging companies would have the knowledge, designers or manufacturing equipment to make successful ESD solutions.
The same can also be said about foam packaging.
Whilst anyone can line a box with foam, or create some inserts, knowing the intricacies of the material, how it behaves, and the optimum material and amounts to provide the required protection, applies to only a handful of companies.
Due to the way in which the wider GWP Group has been formed, your business can benefit from the combined knowledge of 2 divisions – one focusing on conductive packaging, and the other on foam.
With a close collaboration between the two divisions, you can be certain that any anti static foam that you source from GWP, will not only protect from electro static discharge, but can give a tailored level of physical protection too. This can even involve calculating the exact type and amount of foam required using specialist software.
Coupled with being able to source your exterior boxes, totes and packaging from a single source, it is clear that if you need conductive foam of any description, GWP should be your first port of call.
