This material works very similarly and looks very much like asbestos, but it's not toxic. When asbestos was essentially outlawed, it was necessary to find a substitute for many applications where a low cost fiber was needed. This material is made from polyethylene and although it doesn't have the fire resistant properties of asbestos, it retains all of the fibrous qualities. Use in everything from white glue to epoxy resin to achieve thickening and extending.
Same material chemically as Short Stuff , but fluffier. Excellent as a simple to use thickener for silicone rubber. Use as much as you want without having to worry about any adverse chemical reaction. Will work with other materials as well for more of a thickening effect than Short Stuff.
