Abstract
A composition for forming into a soft, pliable, leather-like material includes a polyolefine having from 50 to 90 weight percent of inorganic compounds. The inorganic compounds contain a substantial amount of calcium sulfite having crystal sizes of 1-100 .mu..
Claims2
A polyolefine formed product made of a composition comprising a polyolefine resin and 50-90 wt.% of hemihydrated calcium sulfite, prepared by reacting alkali bisulfite or ammonium bisulfite with calcium carbonate, having crystal sizes of 1 - 30 .mu. in the lateral or smaller dimension and 5 - 100.mu. in the axial or larger dimension, said formed product being capable of becoming soft and pliable when subjected to severe mechanical forces.
A soft and pliable polyolefine formed product having a softening point lower than -50.degree.C and made of a composition comprising a polyolefine resin and 50-90 wt.% of hemihydrated calcium sulfite, prepared by reacting alkali bisulfite or ammonium bisulfite with calcium carbonate, of crystal sizes of 1 - 30 .mu. in the lateral or smaller dimension and 5 - 100 .mu. in the axial or larger dimension.
