Polypropolyne Sheet, available in Natural colour, 3mm thick polypropylene plastic sheet suitable for a wide range of applications.
This low cost, sturdy plastic sheet is perfect for use as a baseboard for many pattern making and mould making projects. Resins like polyester, vinylester and epoxy will not stick to polypropylene which means that once cured the laminating pattern, mould or part can easily be removed from the board.
Because resin won't stick to the sheet it can also be used as a moulding surface for making your own composites sheet (such as carbon fibre sheet, fibreglass sheet or sandwich panel). No release agent or special treatment would be required.
Polypropylene sheet can also be cut in to strips to make flanges or extend flanges around the outside of a mould or to make a removable barrier such as is needed when making a split-mould.
