Abstract

A connection includes: a first profile having a first end, the first profile including a first polymeric material comprising a thermoset material; and a second profile having a second end, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end.

First claim

What is claimed is:

1. A connection comprising:
a first profile having a first end, the first profile comprising a first polymeric material comprising a thermoset material, the first profile comprising a tube having an entire length being a solid, continuous wall of the thermoset material with a terminus at the first end; and
a second profile comprising a solid, continuous wall along an entire length and a circumference of the second profile with a terminus at a second end, the second profile comprising a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end to form a coincident bond, wherein the coincident bond is a circumferential seal.

2. The connection in accordance with claim 1 , wherein the interface has a mechanical strength of at least 2% of a bulk material of the first profile and the second profile.

3. The connection in accordance with claim 1 , wherein the thermoset material of the first polymeric material comprises a silicone elastomer, a diene elastomer, a butyl rubber, a natural rubber, a polyurethane rubber, an ethylene propylene diene monomer rubber, an isoprene rubber, a nitrile rubber, a styrene butadiene rubber, a blend, or combination thereof.

4. The connection in accordance with claim 1 , wherein the second polymeric material comprises a thermoplastic material, a thermoset material, or combination thereof.

5. The connection in accordance with claim 4 , wherein the thermoset material comprises a silicone elastomer, a diene elastomer, a butyl rubber, a natural rubber, a polyurethane rubber, an ethylene propylene diene monomer rubber, an isoprene rubber, a nitrile rubber, a styrene butadiene rubber, a blend, or combination thereof.

6. The connection in accordance with claim 1 , wherein the first profile comprises a silicone elastomer tube and the second profile comprises a silicone elastomer tube.

7. The connection in accordance with claim 1 , wherein the first profile comprises a silicone elastomer and the second profile comprises a blend of a styrene block copolymer and a polyolefin.

8. The connection in accordance with claim 1 , wherein the second profile-comprises a tubing, a port, a connector, a hose, a needle, a nozzle, a plug, or combination thereof.

9. The connection in accordance with claim 1 , wherein the circumferential seal provides fluid flow between a hollow bore of the first profile and a hollow bore of the second profile.

10. The connection in accordance with claim 1 , wherein the coincident bond withstands a seal integrity pressure test of at least 1 psi air pressure for about 30 minutes under dry and wet conditions.

11. The connection in accordance with claim 1 , wherein the coincident bond is provided via surface activation treatment.

12. The connection in accordance with claim 11 , wherein the surface activation treatment comprises processing input energy to a surface of the first profile, the second profile, or combination thereof with wave irradiation, particle irradiation, or combination thereof.

13. The connection in accordance with claim 12 , wherein the wave irradiation comprises microwaves, ultraviolet, x-rays, gamma radiation, or combination thereof.

14. The connection in accordance with claim 12 , wherein the particle irradiation comprises alpha radiation, beta radiation, charged ions, neutron radiation, or combination thereof.

15. The connection in accordance with claim 12 , wherein the particle irradiation comprises corona treatment, ion treatment, plasma treatment, or combination thereof.

16. A connection comprising:
a first profile having a first end, the first profile comprising a first polymeric material comprising a thermoset silicone elastomer, the first profile comprising a tube having an entire length being a solid, continuous wall of the thermoset silicone elastomer with a terminus at the first end; and
a second profile comprising a solid, continuous wall along an entire length and a circumference of the second profile with a terminus at a second end, the second profile comprising a thermoset material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end to form a coincident bond, wherein the coincident bond is a circumferential seal.
