Abstract
Abstract This invention provides flexible compositions which have 20-90% by total weight of composition of a filler selected from the group consisting of barium sulfate, zinc oxide, zirconium oxide, zirconium silicate and mixtures thereof, and a thermoplastic resin, which when filled with 20-90% by total weight of composition of the filler, has a flexural strength of less than 7500 psi.
