A small Welsh plastic engineering company, Protomax has developed a new technology 'P2' to manufacture strong plastic panels including armoured, bullet proof and fire proof doors from virtually any mix of waste material including discarded plastic bags, old milk cartons, discarded drinks bottles, metal components and old clothes. Protomax has been backed by the Welsh Assembly Government with an investment grant towards the design, development and manufacture of the new P2 powder press which is currently being patented.
The outer skin of the panels is made from recycled plastic such as recycled drinks bottles or milk cartons while the core material in the centre can be manufactured from a range of different waste materials. The core material is made by reprocessing waste and mixing it with a foaming agent which fuses the materials together and creates a cellular foam structure. Further strengthening of the panels can be done by adding Kevlar or Glass Fibre - a material used in bullet proof vests or made fire proof by adding anti inflammable agents. P2 technology from Protomax, along with being environment friendly has wide applications. Though panels manufactured using P2 are light and easy to handle, they have excellent tensile strength and weight carrying capacity. The panels, which can be provided in a range of colours and sizes, can also be used to replace plywood hoardings around building sites, used for pallets, partition walls, desk pods, contoured for shed roofing or used as partition walls.
