Additionally, we demonstrate that our method is generally applicable by using it to prepare several other colloidal polymers, such as block-copolymer chains, which are formed by combining rigid and flexible chains, spherocylinders, which are formed by heating rigid chains, and both atactic and isotactic chains, which are formed from heterodimeric-particle monomer units.
Shellac is a natural thermoplastic; that is, a material that is soft and flows under pressure when heated but becomes rigid at room temperature.
For the making of laminated structures, sheets of paper or fabric were impregnated with the resin in an alcohol solution and then heated under pressure to form tough, rigid assemblies.
For instance, materials expand when heated: an ordinary brick wall laid with a rigid mortar can grow as much as 3/4 of an inch in a hundred feet.
To release the membrane from the rigid glass substrate, the sample was immersed in deionized water heated to 55 °C for 1 h.
Basically it is rigid at all times, it only moves when it is heated up out on the track.
One of the materials would bend when heated or immersed in water; the other would hold some parts of the sheet rigid.
One secret to the material's success is that the cross-linking reaction is reversible: when heated to about 300 degrees Fahrenheit, the material becomes unlinked, but as it cools the links re-form, creating a rigid polymer once again.
Only when they were finally freed from the rigid format of the program, in their closing statements, did the two candidates revert to the combativeness that has come to characterize the heated campaign in its final few weeks.
A rigid, heat-resistant, and chemical-resistant plastic, it is used in automobile parts, small appliances, and food-service trays.
