Embodiments of the present disclosure are directed to an IR tube sealing device and method of sealing a polymer tube with infrared energy. In particular embodiments, the IR tube sealing device can be a portable, hand-held device adapted to receive and compress a polymer tube, and produce and direct infrared energy toward the compressed polymer tube to quickly form a permanent aseptic seal.

IR tube sealer and methods sealing a tube

A flexible tubing material includes a mixture of a polyolefin and a styrenic based block copolymer, wherein the styrenic based block copolymer has an A-B-A block configuration and a molecular weight of at least about 350 kg/mol.

Flexible material and articles made therefrom

A thermoplastic elastomer tube can include a thermoplastic elastomer component disposed within a matrix. In an embodiment, the thermoplastic elastomer component is disposed within the matrix in a thermoplastic elastomer phase having a number of domains. At least approximately 50% of the domains of the thermoplastic elastomer component have an aspect ratio of no greater than approximately 1.5. In a particular embodiment, the thermoplastic elastomer tube comprises at least approximately 20 wt % of the thermoplastic elastomer component and no greater than approximately 50 wt % of a polyolefin component. In some embodiments, the thermoplastic elastomer component includes styrene.

Thermoplastic elastomer tubing and method to make and use same

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.

Flexible tubing material and method of forming the material

Flame retardant thermoplastic polyurethane (TPU) compositions are disclosed having a flame retardant package comprising an organo-phosphinate component, an organo-phosphate component, and a polyhydric alcohol. The flame retardant components may be present in an amount from about 5 to about 40 weight percent of the phosphinate compound; from about 5 to about 20 weight percent of the phosphate compound, and from about 0.1 to about 15 weight percent of the polyhydric alcohol, based on the total weight of the TPU composition. Processes are disclosed to make the TPU compositions and to make wire and cable constructions employing the TPU compositions as the jacket of the wire and cable constructions. The TPU compositions exhibit excellent flame retardant capabilities as measured by Limited Oxygen Index testing and/or UL 94 Vertical Burn tests.

Non halogen flame retardant thermoplastic polyurethane

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 polyolefin 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.

A dielectric weldable material includes a blend of at least two components including an inert polymer and an elastomeric polar polymer. A method of forming a bond includes providing a substrate having a first end and a second end, wherein the substrate includes a blend of at least two components including an inert polymer and an elastomeric polar polymer. The method further includes bonding the first end and second end of the substrate with high frequency electromagnetic energy.

Sealable material and method of forming a dielectric weld

In-situ plasticized thermoplastic polyurethane (TPU) compositions are made by a process which involves reacting a polyol, glycol chain extender and a polyisocyanate where the reaction is conducted in the presence of a plasticizer. The reactants together with the plasticizer are added to a reaction extruder and reacted to form the in-situ plasticized TPU.
