This application is a division of parent application, Ser. No' 358,633, filed Apr. 9, 1964. This invention relates to organic polyisocyanates and more particularly to an improved mixture of polyisocyanates which produce polyurethane plastics having improved properties. It has been proposed heretofore to prepared polyurethane plastics from organic polyisocyanates. Moreover, it is known that mixtures of homologous organic polyisocyanates can be made and used together for reaction with active hydrogen containing compounds to prepare polyurethane plastics. The heretofore known mixtures of homologous polyisocyanates have not always been satis factory for the production of polyurethane plastics, particularly polyurethane ...

A polyurethane elastomer actuator comprising a polyurethane elastomer 1 capable of deforming due to the orientation by an electric field, wherein the shrinkage displacement occurring at the time of the application of an electric field is transformed into other displacement. This polyurethane elastomer actuator does not require electrolyte and high voltage. Since it is not accompanied by chemical reactions and heat generation, its durability hardly deteriorates. This actuator deforms largely during driving.

*  5: Spray Polyurethane Foam
Spray polyurethane foam is an insulating foam plastic that's sprayed on as a liquid that expands many times over. Thanks to specialized equipment, application techniques can achieve dramatically different results. The same raw materials, for example, can be made fairly rigid and soft to the touch. They can also be made into roofing foam that's resistant to foot traffic and water. Spray polyurethane foam doesn't just provide an air barrier and method of moisture control -- it also can offer high levels of R-value. Spray polyurethane foam can be used to insulate roofing, air barriers, walls, ceilings, attics and basements. It's effective at low and high temperatures and can provide a more ideal environment for your home's ventilation system so that it functions more efficiently.. ...

Break out your gloves for National Gardening Month!. Of all the tools you need for gardening, your gloves have to be one of the most important. Apart from keeping your hands clean, gardening gloves also help keep your hands dry and better protected from harsh and scratchy substances. Polyurethane gloves are also durable enough to help you pull out those stubborn weeds for many seasons!. Polyurethane garden hoses are another essential gardening tool due to their flexible material. After being stretched to capacity, polyurethane hoses typically spring back into shape. How great is that? Polyurethane helps reduce hoses' weight, taking away a lot of the heavy lifting from gardening. From the moment those seeds get planted in the yard, to picking those delicious tomatoes off that vine, polyurethane is there to make your yardwork a little easier. Happy gardening, everyone!. ...

*  Differences between polyurethane and latex condoms | Go Ask Alice!
So, then what's the deal with the warning labels? Non-latex synthetic condoms are a more recent development and haven't been studied as extensively as their latex counterparts. Because of this, the U.S. Food and Drug Administration (FDA) recommends polyurethane condoms for latex-sensitive or latex-allergic folks. For everyone else, the FDA recommends latex barrier methods. This may explain some of the differences in consumer labeling between the two condom types. So, if you don't have a latex sensitivity, but prefer polyurethane condoms anyway, be assured that polyurethane condoms have been shown to provide the same level of protection as latex ones. They also adhere to the same FDA guidelines for safety and effectiveness - it's just that these conclusions have been drawn from a comparably smaller research base.. As for proper transport and storage, while there's little published research on polyurethane condoms specifically, you should follow the same guidelines that you would for latex ...

*  A study of aerosol entrapment and the influence of wind speed, chamber design and foam density on polyurethane foam passive air...
Polyurethane foam disks are a cheap and versatile tool for sampling persistent organic pollutants (POPs) from the air in ambient, occupational and indoor settings. This study provides important background information on the ways in which the performance of these commonly used passive air samplers may be influenced by the key environmental variables of wind speed and aerosol entrapment. Studies were performed in the field, a wind tunnel and with microscopy techniques, to investigate deployment conditions and foam density influence on gas phase sampling rates (not obtained in this study) and aerosol trapping. The study showed: wind speed inside the sampler is greater on the upper side of the sampling disk than the lower side and tethered samplers have higher wind speeds across the upper and lower surfaces of the foam disk at a wind speed 4 m/s; particles are trapped on the foam surface and within the body of the foam disk; fine (,1 um) particles can form clusters of larger size inside the foam ...

*  Polyurethane
A polyurethane (IUPAC abbreviation PUR, but commonly abbreviated PU) is any polymer consisting of a chain of organic units joined by urethane (carbamate) links. Polyurethane polymers are formed through step-growth polymerization by reacting a monomer containing at least two isocyanate functional groups with another monomer containing at least two hydroxyl (alcohol) groups in the presence of a catalyst.. Polyurethanes are widely used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires, automotive suspension bushings, electrical potting compounds, high performance adhesives and sealants, Spandex fibers, seals, gaskets, carpet underlay, and hard plastic parts (such as for electronic instruments).. Polyurethane products are often called "urethanes". They should not be confused with the specific substance urethane, also known as ethyl carbamate. ...
