CHEMISTRY
Highly fluorescent markers for fluids or articles

The present invention provides highly fluorescent markers, made from a reactive polymer and an isocyanate, that fluoresce in the ultraviolet or near infrared region without being visible to the human eye at low concentrations in the fluid or article being marked. The molecular weight and fluorescence emission wavelength of these highly fluorescent...

Flame retardant and thermal decomposition properties of flexible polyurethane foams filled with...

Expandable graphite (EG), dimethyl methylphosphonate (DMMP), melamine (MEL), zinc borate (ZB), or magnesium hydroxide (MH) was separately added to polyurethane to form flame retardant flexible polyurethane foam (FPUF) in one-step. The cell morphologies of the FPUF composites before and after burning were observed by scanning electron microscopy...

Programming of Temperature-Memory Onsets in a Semicrystalline Polyurethane Elastomer

We demonstrate that phase-segregated poly(ester urethane) (PEU) with crystallizable switching segments of poly(1,4-butylene adipate) (PBA) excels as high-performance temperature-memory polymer. Temperature-memory effects (TMEs) with regard to strain and stress recovering could be programmed by polymer elongation at temperatures below or within the...

New Polyurethane Elastomers with Enhanced Thermal Stability

A series of polyurethane elastomers with enhanced thermal stability was prepared and their physical and thermal properties were studied. For this purpose in the first step, an excess amount of methylene diphenyl diisocyanate was reacted with poly(tetramethylene ether) glycol to produce isocyanate-terminated polyurethane pre-polymer. In the second...

Thermal Aging Effect on Mechanical Properties of Polyurethane

This study concerns the effect of thermal aging on mechanical properties of polyurethane. Polyurethane samples were exposed at 85° and 120°C under inert atmosphere. Mechanical tests were carried out on these samples the aging period. Tensile tests were performed to see the effect of aging on elastic modulus (E), stress (σr), and strain...
