PURPOSE:To produce the titled compsn. having excellent elongation and tensile characteristics and particularly excellent flame retardance, by adding a PVC resin to a chlorinated paraffin, melting the mixture and cooling it to solidify it. CONSTITUTION:At least 5pts.wt. PVC resin is added to 100pts.wt. chlorinated paraffin. The mixture is molten to form a uniform melt which is then cooled to room temp. to solidify it, thus producing the titled compsn. The compsn. has very excellent flame retardance which could not be attained with the foams of conventional resin materials. The compsn. has viscoelasticity and touch similar to agar-agar jelly or protein jelly and is very stable. The compsn. can be used as a cushioning material because of its good elasticity. Further, the compsn. has deformation characteristics having excellent followability so that it is suitable for use as sealing materials, packing materials or toy materials. Furthermore, the compsn. can be used as a buffering material for optical fiber glass.
