Exempel på hur man kan använda POLYURETHANES i en mening

• In 2002 primary materials used included polyvinyl acetate, acrylics, polyvinyl chloride (PVC), polyurethanes, and natural and synthetic rubbers.
• The Huntsman Corporation became the then third-largest petrochemical business in the United States when in 1999, it acquired Imperial Chemical Industries' polyurethanes, titanium dioxide, aromatics and petrochemical global businesses for $2.
• Many polymers are synthesized via step-growth polymerization and include polyesters, polyamides, and polyurethanes.
• Diethylene glycol is used in the manufacture of saturated and unsaturated polyester resins, polyurethanes, and plasticizers.
• Otto Bayer (4 November 1902 – 1 August 1982) was a German industrial chemist at IG Farben who was head of the research group that in 1937 discovered the polyaddition for the synthesis of polyurethanes out of poly-isocyanate and polyol.
• Some good examples are polymers that contain heteroatoms, such as PVC, polyurethanes, polyamides, polyesters, polyacrylates, and polycarbonates.
• They offer the advantage of quick return to service in the case of substrates such as wood, where polyurethanes can take several days before achieving full cure, and longevity in applications such as VCT, where an acrylic finish can be reapplied several times per year and buffed routinely.
• Primary materials used in roof coating formulation include acrylics, asphalt, butyl, coal tar pitch, polyurea, polyurethanes, polyvinylidene fluoride, silicones, and styrene-butadiene.
• Representative shape-memory polymers in this category are polyurethanes, polyurethanes with ionic or mesogenic components made by prepolymer method.
• Rust-Oleum products no longer contain whale oil, instead using resins derived from alkyds, polyurethanes, epoxies, latex, etc.
• It is used to replace common elastomers – thermoplastic polyurethanes, polyester elastomers, and silicones - for these characteristics: lower density among TPE, superior mechanical and dynamic properties (flexibility, impact resistance, energy return, fatigue resistance) and keeping these properties at low temperature (lower than -40 °C), and good resistance against a wide range of chemicals.
• The numbers include thermoplastics and polyurethanes, as well as thermosets, adhesives, coatings, sealants, and PP-fibers.
• Stretchable electronics, also known as elastic electronics or elastic circuits, is a group of technologies for building electronic circuits by depositing or embedding electronic devices and circuits onto stretchable substrates such as silicones or polyurethanes, to make a completed circuit that can experience large strains without failure.
• Hot melt adhesives may consist of various raw materials including ethylene-vinyl acetate (EVA), polyurethanes (TPU), polyacrylate (PA), APOA, and polyolefins (PO).
• Polymers commonly crosslinked using the electron-beam irradiation process include polyvinyl chloride (PVC), thermoplastic polyurethanes and elastomers (TPUs), polybutylene terephthalate (PBT), polyamides / nylon (PA66, PA6, PA11, PA12), polyvinylidene fluoride (PVDF), polymethylpentene (PMP), polyethylenes (LLDPE, LDPE, MDPE, HDPE, UHMWPE), and ethylene copolymers such as ethylene-vinyl acetate (EVA) and ethylene tetrafluoroethylene (ETFE).
• These elastomers are either polyurethanes made by reacting PTMEG with diisocyanates, or polyesters made by reacting PTMEG with diacids or their derivatives.
• Other commonly known products initially commercialized by Bayer include heroin, phenobarbital, polyurethanes, and polycarbonates.
• The use of natural polymers has given way to artificially synthesized polymers such as polyanhydrides, polyesters, polyacrylic acids, poly(methyl methacrylates), poly(phthalaldehyde), and polyurethanes.
• Moisture-cure polyurethanes -- or polyurethane prepolymer -- are isocyanate-terminated prepolymers that are formulated to cure with ambient water.
• Available coatings include polyesters, plastisols, polyurethanes, polyvinylidene fluorides (PVDF), epoxies, primers, backing coats and laminate films.
