    Plasti thread, Relic wrap®

    A synthetic fluoropolymer made by DuPont. Teflon® is chemically inert, nontoxic, and nonabsorbent. It is extremely stretchable in all directions and can easily conform to the shape of an object and/or cavity. However, it is extremely thin and can tear if used with ojects that are to sharp, heavy or when stretched too far.

    12” rolls; thicknesses -- up to 3 mil.


    Mostly used with light objects with extremely fragile surfaces – e.g. used in conjunction with polyester batting to conform to complex shapes, and help mitigate vibration. An excellent non-abrasive lining for cavities or covering for cushioned surfaces. Because the film is thin and pliable it conforms without adding bulk. Use two layers at a time to gain strength without compromising desirable properties. It can be used to stabilize objects by "tying" objects in place. Can be adhered to surfaces with Low-melt adhesive.
