In 1938 Roy J. Plunket, a recent hire at DuPont, discovered polytetrafluoroethylene (or Teflon)—a fluoropolymer that led to the invention of synthetic rubber. [2] His early discovery led 3M scientists to develop the formula for Scotchgard, discovered by accident in 1953 when Joan Mullan—a 3M lab technician—spilled a few drops of a fluorochemical liquid destined for rubber jet fuel hoses ...
Scotch-Brite was introduced during the 1950s. Development continues into the 21st century with new products for various cleaning uses. [2]Scotch-Brite, and similar abrasives, have largely replaced the use of bronze wool, which had been used as a non-rusting alternative to steel wool, for use on materials such as oak that would be sensitive to rust.
It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorine Kautschuk Material. [ 3 ] All FKMs contain vinylidene fluoride as the common monomer , to which different other monomers are added for specific types and functionalities, fitting the desired application.
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 ...
It is also used by speaker driver manufacturers as the material for low damping rubber surrounds. Additionally, it is used in some rubber cutting boards. SBR is also used as a binder in lithium-ion battery electrodes, in combination with carboxymethyl cellulose as a water-based alternative for, e.g. polyvinylidene fluoride. [9]
Silicone rubber is a reliable solution (as opposed to rubber and thermoplastic elastomers) for migration or interaction problems between the main active ingredients. Its chemical stability prevents it from affecting any substrate it is in contact with (skin, water, blood, active ingredients, etc.).
