Moldable Plastic Instructions

Safety First

  • Be careful to avoid burns when working with hot water, hot moldable plastic, stove tops, ovens, heat guns and hair dryers, etc
  • Pellets pose a choking hazard for children under 3. Due to potential for burns, supervise children under 7.
  • Product is not meant for internal use.

Usage Instructions

  • Heat water to above 150 degree F using a microwave or stove top.  If the water is boiling, allow it to cool to prevent possible injury.
  • Place the desired amount of Polly Plastics Moldable pellets into the hot water to soften.  After a few minutes in hot water, the pellets will turn completely clear and begin sticking to each other.  If you are making a larger part, you may find it useful to start with a smaller number of pellets and gradually build up your part.
  • Remove the pellets with tongs or utensil and shake off any excess water. Wear gloves to avoid burns.  Take care that the hot plastic doesn’t stick to things you don’t want it to such as certain plastics (acrylic, vinyl, PVC, polystyrene, PET, ABS), fingernail polish, fabrics or metal.  A sheet of parchment paper or glass dish makes a great surface to work on, preventing sticking. 
  • With clean hands, begin forming the pellets into your desired shape. You can use your hands, craft with tools, apply onto existing objects or press into molds you have prepared. You can use a heat gun to make final touches.
  • For color, use Polly Plastics Color Pellets.  Or add paint powder or alcohol ink (found at craft stores like Michaels or Hobby Lobby) into the hot pellets while you are working them. Or you can paint the part after it cools with acrylic paints or permanent markers – without coloring, the part will be white.  Spraying on a coat of primer for plastics will help adhesion and you can spray on varnish  after painting, to prevent flaking.
  • Let your part completely cool to take a strong, permanent shape.  Cover it with cold water or place in the freezer if you want to speed up the process. If you don’t like the outcome, reheat and mold it again.
  • Once cooled, you can sand, drill, varnish or paint the part you have made. You can also use a super glue the part to other things.
