Exempel på hur man kan använda URETHANES i en mening

• Typical matrix materials are epoxies, silicones (silicone grease), urethanes, and acrylates; solvent-based systems, hot-melt adhesives, and pressure-sensitive adhesive tapes are also available.
• This segment markets synthetic lubricants and greases, synthetic basestocks, lubricant additives, and urethanes.
• The company also works in product development and design, including quick-turnaround projects using urethanes, silicones, glass/carbon fibers, braided fiberglass, thermoplastics, electronics, hydraulics, and pneumatics; the creation of prototypes, master patterns, and tooling; reverse engineering; laser scanning; and manufacturing using 3D printing, 3-axis CNC router, 4-axis CNC machining, and a triaxial fiberglass braider.
• Kurt Gingold, Synthesis and Physical Chemistry of Urethanes (Soviet Progress in Polyurethanes series).
• Various dynamic chemistries have already been incorporated in CANs; some of the more notable ones include transesterification, Diels-Alder exchange, imine metathesis, disulfide exchange, transamination of vinylogous urethanes, transcarbamoylation of urethanes, olefin metathesis, and trans-N-alkylation of 1,2,3-triazolium salts.
• Common degradable polymer materials used in drug eluting implants include poly e-caprolactone (PCL), polylactic-co-glycolic acid (PLGA) and poly-L-lactic acid (PLLA), while non-degradable polymer materials include silicones commonly used in plastic surgery, urethanes and acrylates, and are more likely to be used in the treatment of chronic conditions in which long term implantation is to be expected.
