A multiple layer structure comprising a skin layer composed of a polypropylene copolymer with styrene ethylene-butene styrene block copolymer within a range of 0-20% by weight skin layer, and, a radio frequency ('RF') susceptible layer adhered to the skin layer. The RF layer has a first component of a propylene based polymer, a second component of a nonpropylene polyolefin, a third component of a radio frequency susceptible polymer, and a fourth component of a polymeric compatibilizing agent.

Multi-layered polymer structure for medical products

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 the range a&lt;40,000 psi; b&gt;=70%; c&lt;30%; d&gt;1.0; e&lt;0.1%; f&lt;0.1%; g&gt;=0.05; h&lt;=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.degree. to 250.degree. C. of the composition; h sample creep measured at 121.degree. 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.
