including high durability, resistance to abrasion, and elasticity. There are two primary types of polyurethane: polyether-polyurethane and polyester-polyurethane. While both types have similar characteristics, they differ in some key areas, which we will explore in this article....

TPU, also called polyurethane, has two types: polyester type and polyether type. Both TPE and TPU are thermoplastic materials with rubber elasticity. For TPE and TPU materials with similar hardness, it is sometimes difficult to distinguish TPE or TPU by visual observation alone. But starting from...

At room temperature, some polyesters can form soft segments and affect the properties of polyurethanes. The strength, oil resistance and thermal oxidation stability of polyester polyurethane are hig...

TheCalvin Klein Jeans logo-print satchel baghas a boxy silhouette and is crafted from glossy black polyurethane for a durable finish so you won’t have to worry about this bag getting scratched or scuffed. The front of the bag has been decorated with a large Calvin Klein Jeans logo in st...
The calculated ~nolecularweight of I X is 382, so a polyester structure is not involved. The configuration of VIII and I X must therefore be J J as well. I t may be expected that the chloronlercurial X I derived from VIII by acidification with hydrochloric acid also will have the J ...
Step 4: Get sandy.The sanding process isn’t always necessary (for example, our cabinets weren’t glossy so we skipped it and went straight to priming) but for some people with super shiny cabinets (aka: lots of polyurethane) it can’t hurt to run an electric sander over everything- ...
As such the pressure-sensitive adhesive, for example, a dry laminating adhesive obtained by mixing a polyurethane-based resin solution and a polyisocyanate resin solution, a styrene butadiene rubber-based adhesive, and an epoxy-based two-pack type adhesive (comprising two liquids of an epoxy resin...
