An alarming study that had Americans tossing out their black plastic kitchen utensils, toys and to-go packages earlier this month overstated the concern, the researchers admit.
This is of particular interest in the area of polyurethane coatings, where light stability is a critical factor and is the main reason that aliphatic isocyanates are used in making polyurethane coatings. When PU foam, which is made using aromatic isocyanates, is exposed to visible light, it discolors, turning from off-white to yellow to reddish ...
Polyurethane laminate (PUL, thermal stretch, [1] fuzzy rubber [1]) is a compound fabric made by laminating a cloth fabric to one or both sides of a thin film of polyurethane. [ 1 ] [ 2 ] Polyurethane laminated fabrics have a wide range of applications in medical, automotive and garment uses.
Non-stick pans must not be overheated. The coating is stable at normal cooking temperatures, even at the smoke point of most oils. However, if a non-stick pan is heated while empty its temperature may quickly exceed 260 °C (500 °F), above which the non-stick coating may begin to deteriorate, changing color and losing its non-stick properties ...
Heat waves are sweaty, uncomfortable, even health-endangering, but scientists have come up with an innovation they say could provide relief.
Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
The coating is an application of chemical substances on the surface of fabric that is to be made functional or decorative. [24] Coating is attained by applying a thin layer of a functional chemical, compound, or polymer on the substrate's surface. Coatings use less material than other types of applications, such as exhaust or padding. [25]
