Abstract
A conformable polymeric composition containing a polymeric material melt-blending from a composition containing (a) from about 50 to about 80 wt. % of at least one polyester thermoplastic polymer which is amorphous or becomes amorphous when melted, and (b) from about 20 to about 50 wt. % of at least one elastomeric polymer which has a flexural modulus of less than 700 MPa and a glass transition temperature less than 25° C., based on the combined weight of (a) and (b), wherein the composition is characterized by: a dead fold angle equal to or less than about 20°.
