In 2007, the global consumption of polyurethane raw materials was above 12 million metric tons, and the average annual growth rate was about 5%. [46] Revenues generated with PUR on the global market are expected to rise to approximately US$75 billion by 2022. [ 47 ]
Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.

This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
As of 2019, it is the world's largest producer of the polyurethane raw material methylene diphenyl diisocyanate (MDI). [15] According to another source, the listed company is the second largest producer of the world for aliphatic diisocyanate (ADI) as well as the largest producer of China for toluene diisocyanate (TDI).

Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
I know the Chiefs are sailing along merrily at 12-1, but don't fear this matchup or this defense. Kansas City has actually allowed the 11th-most fantasy points to opposing quarterbacks.
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
In 2022, Sharecare announced one of its brands had become "available as a free in-home personal care benefit to more than 1.5 million Medicare Advantage members." The number reached 2 million in ...
