Poly(urethane)PolyurethaneTPUSustained releaseAtomic force microscopyMembraneImplantImplants offer the opportunity to improve patient adherence and real-world outcomes. However, most polymers used today are hydrophobic and limit drug properties suitable for development. Thermoplastic poly(urethanes) (TPUs) ...
After sanding, use a cloth and/or vacuum cleaner to remove dust. Any impurities that get into the polyurethane will slow drying. Something as simple as choosing to work on a warm, sunny day can have an impact. The temperature is higher, and humidity is lower. For best results, both ...

摘要: A process for preparing durable dry-spun, polyurethane fiber exhibiting a small angle X-ray scattering pattern that forms a layer line scattering image or an eyebrow-shaped four dot scattering image is provided. The fiber is particularly useful in pantyhose, undergarments and the like....
To prevent gouges, work along the slab edge rather than across it. When we peeled the bark from this cherry slab we discovered a complex network of worm tracks, a feature worth highlighting. With the bark removed, use a small nylon or wire brush to gently scrub away loose or stringy ...
Unlike metal braces, clear aligners are not attached to the teeth. However, because of this, attachments to your teeth, aptly named “attachments,” that work with the clear aligner and are sometimes needed to support the aligner treatment. The attachments are bonded to your teeth and are ...
Latex or plastic condoms.Most people use condoms made of latex. If you’re sensitive or allergic to latex, you can use ones made of a plastic called polyurethane or a human-made version of latex called polyisoprene. Latex and plastic condoms protect you from STDs during any kind of sex:...
which can not be reused. The difference between the two condoms is that shape. Compared to male condom, female condoms are quite large in size and more than double the size of male condom. There are also differences in materials, but both polyurethane condoms of the same material are ...
Using polyurethane research, DuPont sought to create a new polymer fabric with high elasticity. During the development process, scientists at DuPont referred to this fabric as "spandex;" once this fabric was completed, it was sold under the brand name Lycra, but consumers seemed to prefer to ...
