What You'll Learn
Heat sheets above 150°F for 2-3 minutes until they turn clear
To shape Polly Plastic Sheets, you must first soften the sheets by heating them above 150°F. This can be done using a heat gun, or by placing the sheets in hot water. If you are using hot water, heat the water in a pot or pan using a microwave or stove. If the water is boiling, allow it to cool first to prevent possible injury.
Once the water or heat gun has reached the desired temperature, heat the sheets for 2-3 minutes. You will know that the sheets are ready to be moulded when they turn from white/translucent to clear. Be very cautious to avoid burns when removing the sheets from the hot water. Use tongs, a spoon, or a fork to handle the sheets, and shake off any excess water. If you are sensitive to heat, wear heat-resistant gloves.
To prevent the hot plastic from sticking to your work surface, place a sheet of parchment paper or a glass dish underneath. Take care that the plastic doesn't come into contact with certain materials, such as acrylic, vinyl, PVC, polystyrene, PET, ABS, fingernail polish, fabrics, or metal.
Once the sheets are softened, you can begin forming them into your desired shape. This can be done using your hands, craft tools, or by applying the plastic onto existing objects. You can also join multiple sheets together by heating the surface of one sheet and attaching another sheet on top of it or beside it.

Use a heat gun, hot water, or hair dryer to soften the sheets
Polly Plastics sheets are made of thermoplastic beads, which can be melted and moulded into any desired shape. To shape the sheets, you must first soften them by heating them to a temperature above 150°F (65.5°C). This can be achieved using a heat gun, hot water, or a hair dryer.
If you are using a heat gun, place the plastic on a heat-proof surface, such as a metal sheet or concrete block, in a well-ventilated outdoor area. Turn on the heat gun and apply it to the plastic using slow, sweeping motions. Be patient and avoid subjecting the plastic to direct, intense heat to prevent burning. You can also use an oven to heat the plastic, preheating it to around 300°F (149°C). However, be cautious as high temperatures can cause the plastic to smoke and burn quickly.
To use hot water, heat the water in a pot or pan to above 150°F (65.5°C) using a microwave or stove. If the water is boiling, allow it to cool slightly to prevent possible injury. Place the plastic sheet in the hot water and wait for it to soften. You can also heat the plastic sheets in the hot water along with Polly Plastics Color Pellets to add colour.
If you prefer to melt only a portion of the sheet, you can cut it with shears or scissors before applying heat. Once the plastic sheet becomes clear, it is soft enough to form and mould. Remove the softened plastic from the water using tongs, a spoon, or a fork, being cautious to avoid burns. Shake off any excess water and place the plastic on a sheet of parchment paper or a glass dish to prevent sticking.
You can also use a hair dryer to heat and soften the sheets. However, a heat gun will allow for higher temperatures and more control over the softening process.

Shape the sheets with your hands or tools
Polly Plastics Moldable Plastic Sheets can be shaped using your hands or tools. The sheets are heated above 150°F for 2-3 minutes using a heat gun or hot water until they turn from white/translucent to clear. A hair dryer can also be used to heat the sheets, but a heat gun will give you higher temperatures and more control. You can also cut the sheets with scissors, shears, or a box cutter to get the desired shape.
Once heated, you can use your hands to mould the sheets into your desired shape. You can also use tools to help you craft your desired shape. The sheets can be applied to existing objects, and you can join sheets together by heating the surface of one sheet and attaching it to another sheet. The sheets are flexible and can be wrapped around objects or moulded into complex shapes.
If you are unhappy with your initial shape, you can reheat and remould the sheets as many times as needed. The sheets can be cut with a sharp hobby knife, both when hot and cold. You can also melt only part of the sheet by cutting it with shears or scissors and then reheating it.
When working with the sheets, it is important to be cautious to avoid burns. You can use tongs, a spoon, or a fork to handle the sheets when they are hot, and you can wear heat-resistant gloves if you are sensitive to heat. It is also important to work on a surface that the plastic will not stick to, such as a sheet of parchment paper or a glass dish.

Reheat and reshape as needed
Polly Plastics Moldable Plastic Sheets can be reheated and reshaped as needed. The sheets can be heated and moulded into any shape, and if you are not satisfied with the outcome, you can reheat and modify the sheets until you are happy with the result.
To reheat the sheets, you can use a heat gun, hair dryer, or hot water. If you are using hot water, heat the water in a pot or pan to above 150 degrees Fahrenheit using a microwave or stove, and then place the sheet in the water to soften. If you are using a heat gun or hair dryer, simply apply heat to the sheet until it reaches the desired temperature.
Once the sheet is soft, you can use your hands or tools to mould it into the desired shape. You can also cut the sheets with scissors, shears, or a box cutter to create different shapes. If you are joining two sheets together, heat the surface of one sheet and attach the other sheet to it, either on top of it or beside it.
It is important to work quickly as the plastic will start to harden within a few minutes of being removed from the heat source. If the plastic begins to harden before you are finished working with it, you can always reheat it to make it more mouldable again.
In addition to reshaping the sheets, you can also add colour to them by using Polly Plastics Color Pellets, paint powders, alcohol inks, or acrylic paints. You can mix the colour into the plastic while it is molten or paint the sheet after it has cooled.

Paint, drill, sand, varnish, or glue the sheets
Painting Poly Plastic Sheets
Poly plastic sheets can be painted using powder paint or alcohol dye, which can be added to the molten plastic. Alternatively, you can apply acrylic paints or special spray paints for plastics after the plastic has cooled. To lock in the colour, add a polyurethane top coat.
Drilling Poly Plastic Sheets
When drilling polycarbonate, it is important to ensure that the sheet is well-supported. Place it on a flat surface, such as a wooden board, and clamp it down using locking pliers or glue clamps to prevent it from moving. Use a slightly used drill bit or break in a new one by drilling some holes into a piece of wood first. This will help to avoid sharp edges. Mark the drill holes with masking tape to ensure that the drill doesn't slip and scratch the surface. Position the drill perpendicular to the sheet and run it at medium speed without applying too much pressure.
Sanding Poly Plastic Sheets
Although specific instructions for sanding poly plastic sheets could not be found, general instructions for sanding plastic were found. When sanding plastic, it is important to prioritise safety due to the potential toxicity of the process. Wear personal protective equipment, such as gloves and goggles, and keep the work area well-ventilated to avoid inhaling any debris.
Varnishing Poly Plastic Sheets
Before varnishing, clean the surface of the poly plastic sheet to ensure it is free of dirt, dust, and other debris. If needed, use a damp cloth to wipe down the surface and allow it to dry before applying the varnish. Choose the right brush for the type of varnish you are using. Natural bristle brushes are recommended for oil-based varnishes, while synthetic or nylon brushes are better suited for acrylic or water-based varnishes.
Gluing Poly Plastic Sheets
To glue poly plastic sheets, first identify the type of plastic. Polyethylene and polypropylene plastics, for example, require specific adhesives designed for these materials. For polystyrene plastics, use poly cement or a specialised plastic glue. For ABS plastic, epoxy cement or ABS solvent cement can be used, although it may alter the shape of the surface. When gluing, apply an even layer of adhesive to both surfaces and press them together lightly to remove any air bubbles. Clamp the pieces together if using a solvent cement.
