SCA Foam Products has developed a new method by which a skin can be produced on an EPP or EPS moulding as part of the moulding process.

• Provides increased surface tensile strength
• Skin is very durable
• Skin is squeak free
• Robust hinges can be made
• Varied finishes, textures & colours
• Potential for skin to be made to form an impervious membrane exists

• The SupraSkin process produces a fully fused end product, unlike conventional skinning processes
• SupraSkin can be moulded on conventional moulding equipment
• Skin thickness can be varied
• SupraSkin will provide increased strength, penetration and liquid resistance
• Partial or complete coverings are possible
• SupraSkin is relatively low cost for the number of benefits available
• Recyclable (due to low relative volume to base material it is suitable for recycling)

The skinning of a foam body is normally taken on for aesthetic or technical reasons. To this date it has not proven possible to satisfactorily provide such a surface layer on a foam body during its formation in a mould. This is because the expanding / fusing medium is normally introduced to the mould from all sides to ensure even treatment of the beads in the mould.

The base material is partially fused in the tool acquiring its required shape. The tool is then opened. Next the skin material is laid over the required surfaces. Then finally the tool is closed and the fusion process completed to leave a very strong and detailed surface.
