Polymeric compositions for medical packaging and devices.

Abstract

Multiple constituent polymer material for the manufacture of articles, comprising: a heat-resistant polymer, a high frequency ("HF") -sensitive polymer, a miscibility polymer. The material has physical properties in the range a <275,790 MPa; b> »70%; c <30%; d> 1.0; e <0.1%; f <0.1%; g> = 0.05 h <= 60%, i-O; wherein: a is the mechanical module of the material according to ASTM D-882; b is% recovery in length of material after 20% deformation; c is the optical blur of the material processed into 228.6 micron thickness films and measured according to ASTM D-1003; d is the loss key of the material at 1 Hz at melt processing temperatures; e is the material weight content of elemental halogen, f is the material's water-soluble fraction of low molecular weight constituents; g is the dielectric loss of the material between 1 and 60 MHz at temperatures of 25 to 250 ° C; h is shrinkage measured at 121 ° C on a 25.4 mm strip of material at 186,158 kPa load; and in the material, no stretch whitening shows after stretching at 50 cm / min until about 100% elongation and stretch whitening (indicated by l) or lack thereof (indicated by 0) is noted.
