The PIM process can utilise mixed plastic waste with a high level of contaminants such as paper or soil as a raw material feed stock. The waste plastics require limited to no segregation, reducing costs, providing a low cost raw material which in turn improves product profit margins.

The products made using the PIM process are themselves recyclable and can be reused as a feedstock to make new products.

The PIM process works by melting and fusing thermoplastic rich powder.  This powder is applied to the open surfaces of heated moulds.  A core material of mixed plastics is added along with any further components such as reinforcements or fixings.

On further processing a composite material is formed comprising solid skins fused to a closed cell foam core. This material exhibits excellent mechanical, thermal and sound insulation properties as well as being light-weight. Through material selection and by adjusting the process conditions the density and properties of the composite material can be manipulated.

By utilising open moulds it is possible to form composites with different skins on each surface with different material properties and colours.

Both the skins and core of the product can be made from mixed recycled plastic.
