| 21. | It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde.
|
| 22. | For thermosetting plastics that require only one monomer, the monomer compound is the " resin ".
|
| 23. | You've got urethanes, sheet-molding compound and any of several thermosetting plastics to match.
|
| 24. | While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.
|
| 25. | When heated in the presence of acids, furfural irreversibly solidifies, i . e . a thermosetting polymer.
|
| 26. | "' Duroplast "'is a composite thermosetting plastic, a close relative of formica and bakelite.
|
| 27. | Like its predecessor the MP-444, the 445 features a frame made from super strong thermosetting plastic material.
|
| 28. | Polyurethane is a thermosetting plastic with no solvents, with a three-dimensionally linked molecular structure giving it mechanical stability.
|
| 29. | One consequence of this is that typical polyurethanes do not soften or melt when they are heated; they are thermosetting polymers.
|
| 30. | In 1943, the thermosetting phenolic resin was even considered for the manufacture of coins, due to a shortage of traditional material.
