Elasta-Plastic is a unique molding material which initially resembles stiff perforated plastic sheeting. It is great for masks, costumes, millinery, castings & hand molded sculptural pieces. When heated it becomes soft, allowing it to be streched, molded and shaped by hand or on a mold or block. Once cooled it retains the molded shape. This process of heating and cooling can be repeated until the desired shape is acquired. If re-activated and allowed to be suspended in water, it will return to its original unstretched shape. Please note that the ACTIVATION TEMPERATURE for Elasta-Plastic is 70-75°C.
Elasta-Plastic makes for an excellent overlay for alternate colours as the perforations allow for exposure of the layer underneath. The surface is capable of stretching, molding like putty once it has been heated but will snap under too much tension (see below for heating instructions). If snapped, the affected area may not be able to be repaired. This product contains a surface layer which prevents self-adhesion. Hence it will not stick easily to itself unless this layer is removed. This can be done via scraping or by brushing with acetone and then heating the selected area to activate it. For sticking thermoplastics, we also recommend external adhesives such as UHU glue.
Heating is recommended using boiled water which has been cooled slightly. Dry heating can be used with a heat gun but may not give a consistent activation throughout the product. If using an oven, care must be taken not to overheat as this material will absorb heat easier this way. If placed in water, and activated, the stretched form of this product will attempt revert to it's old shape (including the size of the perforations) but will never be 100% the same as it originally was. To heat, place a sheet in a bowl or container of near-boiling water for around 1-2 minutes until soft (The white version of this plastic becomes transparent. Coloured variants vary but may become slightly transparent to some degree). Once soft, it can be stretched over a block or desired molding shape. The size of the holes will increase with stretch. Elasta-Plastic should remain moldable for approimately 4 minutes after activation.
PLEASE NOTE: When heated, Elasta-Plastic should not be applied directly to bare skin as burns may occur.
