Abstract
A tube includes: a substrate including a sidewall defining a lumen profile along a central axis, where the substrate includes a composition including a silicone polymer, an inorganic filler, a cross-linking component, and a catalyst, where the tube has a minimum yield strain of 5%, where the tube has a minimum tensile strength of 12 MPa, where the tube has a minimum tear strength of 15 N/mm, where the tube has a minimum toughness of 0.26 MPa, and where the tube has a minimum tensile modulus of 120 MPa.
Claims20
A tube comprising:
- a substrate forming a sidewall defining a lumen profile along a central axis, wherein the substrate comprises a composition comprising a silicone polymer, an inorganic filler, a cross-linking component, and a catalyst, wherein the tube has a minimum yield strain of 15%, wherein the tube has a minimum tensile strength of 12 MPa, wherein the tube has a minimum tear strength of 5 N/mm, wherein the tube has a minimum toughness of 0.26 MPa, and wherein the tube has a minimum tensile modulus of 120 MPa.
A method comprising:
- providing a substrate comprising composition comprising a silicone polymer, an inorganic filler, a cross-linking component, and a catalyst;
- and
- forming a sidewall from the substrate, the sidewall defining a lumen profile along a central axis to form a tube, wherein the tube has a minimum yield strain of 5%, wherein the tube has a minimum tensile strength of 12 MPa, wherein the tube has a minimum tear strength of 15 N/mm, wherein the tube has a minimum toughness of 0.26 MPa, and wherein the tube has a minimum tensile modulus of 120 MPa.
