Abstract:
A flexible tube includes a first layer comprising a polyolefin material having a flexural modulus of not greater than 150 MPa and includes a second layer directly bonded to and in direct contact with the first layer. The second layer comprising a blend of propylenic polymer and styrenic block copolymer.
Abstract:
A flexible tubing material includes a radiation crosslinked blend of a first elastomeric polymer including a styrenic thermoplastic elastomer, an ethylene vinyl acetate elastomer, a polylefin elastomer with a second elastomeric polymer including a polyolefin elastomer, a diene elastomer, or combination thereof, with the proviso that the first elastomeric polymer and the second elastomeric polymer are different. In an embodiment, a method of making a material includes providing the first elastomeric polymer, providing the second elastomeric polymer, blending the first elastomeric polymer and the second elastomeric polymer, extruding or injection molding the blend, and crosslinking the blend with radiation.
Abstract:
The disclosure is directed to a silicone composition. The silicone composition includes a silicone matrix component, an adhesion promoter, and a quaternary ammonium salt containing polymer, wherein the quaternary ammonium salt containing polymer is in an amount to provide a bactericidal effect to the silicone composition. The disclosure is further directed to an article made thereof and to methods for making the article.

Abstract:
An apparatus for forming a silicone article is disclosed. The apparatus includes an pumping system to deliver the silicone formulation to a die, the silicone formulation having a viscosity of less than about 2,000,000 centipoise; the die having a distal end, a proximal end, and a channel there between, wherein the silicone formulation flows through the channel of the die; and a source of radiation energy, wherein the radiation energy substantially cures the silicone formulation as the silicone formulation flows out the channel of the die to form the silicone article. The present disclosure further includes a method of forming the silicone article, a silicone tube, and a silicone extrudate.
