Polymeric compositions for medical packaging and devices |
摘要 |
Multiple component polymer compositions for fabrication into articles. In particular, polymeric compositions comprising a heat resistant polymer; a radio frequency ("RF") susceptible polymer; a compatibilizing polymer; the composition having physical properties within a range a<40,000 psi; b>=70%; c<30%; d>1.0; e<0.1%; f<0.1%; g>=0.05; h<=60%; i=0; wherein: a is the mechanical modulus of the composition measured according to ASTM D-882; b is the percent recovery in length of the composition after an initial 20% deformation; c is the optical haze of the composition being 9 mils in thickness according to ASTM D-1003; d is the loss tangent of the composition at 1 Hz measured at melt processing temperatures; e is the elemental halogen content by weight of the composition; f is the low molecular weight water soluble fraction of the composition; g is the dielectric loss between 1 and 60 MHz and over temperatures of 25 to 250° C. of the composition; h sample creep measured at 121° C. for a 1 inch strip of the composition under 27 psi loading; and, i indicates the composition exhibits no strain whitening after being strained at moderate speeds of about 20 inches (50 cm) per minute to about 100% elongation (twice the original length) and the presence of strain whitening (indicated by 1) or lack thereof (indicated by 0) is noted.
