Welcome to Polly Plastics

Welcome to Polly PlasticsPlease browse our site to see the wide variety of moldable plastic, rock tumbling supplies and silicone molding putty that we provide for crafting, hobbies, cosplay, prototyping and repair.  We only sell quality products that are packaged securely at our facility in Michigan.

Here’s a summary of what we sell:


MOLDABLE PLASTIC – This material is technically a polyester plastic called polycaprolactone.  You don’t need that detail to love what this can do.  It melts in hot water at low temperatures above 150 degrees F.  You can get water above 150 F. on your stovetop or in the microwave.  Once the pellets turn clear in a couple of minutes, you can scoop the pellets out and shape them however you want.  People use these pellets to MAKE stuff like costumes, props, toys or figurines.  Or you can MEND things that have broken.  Lastly, you can MODIFY things to make them more ergonomic or functional.  We include a helpful booklet with each moldable plastic purchase to provide instruction and ideas.

If you want the parts to have color, rather than the normal white, we sell color and metallic pellets that you can heat along with the moldable pellets.  Squish them all together and your part will now be colored.  We include a color chart with our color pellets so you can make any color you desire.  If you prefer, you can paint the parts with acrylic paint or spray paint.

SILICONE MOLDING MATERIAL – You can use our silicone molding putty to make simple molds without 2 part liquid systems or mold boxes.  Just grab an equal amount of the white Part A and the blue Part B, knead it together and form around the part you want to replicate.  In about 30 minutes, you’ll have a silicone mold that you can use repeatedly to duplicate parts.  We also sell a kit with our silicone molding putty and moldable plastic together to create plastic parts that you can replicate.

ROCK TUMBLING GRIT AND MEDIA – We have the rock tumbling grit and filler media you need to create beautifully polished stones.  There are 4 stages of grit that you need to do a compete tumbler cycle.  We sell the grit in 4 step kits or in individual packs.  Ceramic cylinders and plastic pellets tumbler media are used to fill rock tumbler chambers to cushion the stones while they are tumbling.  They also will quiet the tumbler.

So there you have it, our current line of products.  We’re growing and would love to hear from you if you have ideas for other products.  Drop us a line on our contact form.
