In the 1840s, Friedrich Ludersdorf and Nathaniel Hayward independently synthetic polymer, a thermosetting phenol & ndash; formaldehyde resin called Bakelite.
32.
Meanwhile, the Italian factory at Montebelluna was experimenting with a new custom-fit liner, using a thermosetting plastic called Thermofit.
33.
In most cases, cross-linking is irreversible, and the resulting thermosetting material will degrade or burn if heated, without melting.
34.
In all cases the anisotropic material, for example, a thermosetting resin containing conductive particles, is first deposited on the base substrate.
35.
Bifunctional monomers lead to linear chains, and therefore thermoplastic polymers, but, when the monomer branched chain that may be a thermosetting polymer.
36.
The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms.
37.
Melamine is used combined with formaldehyde to produce melamine resin, a very durable thermosetting plastic, and melamine foam, a polymeric cleaning product.
38.
This packing ring is generally made up of NFTC ( Natural Fiber Thermosetting COMPOSITE ) or UHMWPE ( Ultra-high molecular weight polyethylene ) material.
39.
Some are thermoplastic or thermosetting, others are chemically cured and are mixed with a catalyst ( polyester ) or hardener ( epoxy ) before moulding.
40.
Thermosetting mechanisms, on the other hand, are true curing mechanism that involve chemical reaction ( s ) among the polymers that make up the binder.
