Aluminium chloride can both degrade and stabilize PVC: but how does it do it?doi:10.1016/s0306-3747(97)89806-5ELSEVIERAdditives for Polymers
In addition, bacteria and microorganisms help to break down the polymers into CO2 and methane, among other things. Mechanical wear, wind and weather also contribute to the wear and degradation of ropes and gear. SHOW MORE The tip of an iceberg One of the partners in the project is the ...
Heat is applied to the lactic acid polymers, causing them to link together and form a long chain that ultimately becomes the material used to make many corn plastic products. What sets corn plastic apart from petroleum-based plastic is that the process used to make it can also be reversed ...
The evolution of the plastic bottle from amazing to scourge of land and sea has played out inside of a generation.
and functional applications. While often associated with plastic filament, material extrusion 3D printing can handle a variety of materials including polymers reinforced with carbon fiber, plastic mixed with metal powders, wood-based polymers, food, and even concrete – making it a versatile technology...
In respect to polymers, nylons and polyesters were substituted by materials less likely to degrade such as polytetrafluorethylene (PTFE), polymethylmetacrylate (PMMA), polyethylene and silicones. In the 1980s there were more than a hundred implants and devices in clinical use made from about 30...
Lasso-like entanglements are common in the native fold of proteins and entanglements more generally have been a subject of interest to the polymer community for 60 years46,47,48,49,50. In the 1960’s, scientists noticed entanglements in synthetic polymers51, and found polymer composition, pola...
But heat exchangers can also be made of ceramics, composites (based on either metals or ceramics), and even plastics (polymers).All these materials have their advantages. Ceramics are a particularly good choice for the kind of high-temperature applications (over 1000°C or 2000°F) that would...
Alcohols (although not all alcohols are bad, many can degrade your hair cuticle and are almost always found in aerosol sprays, like canned hairspray and dry shampoo. Thus, welcome to your new BFFs: alcohol-free dry shampoo and alcohol-free hairspray) What products do you need for the Curly...
