| 21. | The filled mold then continues to spin as the metal solidifies or the thermoset plastic sets.
|
| 22. | Thermoset foams, such as spray foam insulation, have the ability to reflect radiant heat.
|
| 23. | Thermosets can melt and take shape once; after they have solidified, they stay solid.
|
| 24. | In the early 30's, companies started to experiment with housings of thermoset polymer plastics.
|
| 25. | Thermoset polymer matrix properties can be fine tuned by the choice of substituents in the bisphenolic compound.
|
| 26. | The cut of polyimides is, highest of all thermosets, with short term exposure capabilities of.
|
| 27. | Thermosets cannot be melted, therefore, once a thermoset has set it is impossible to weld it.
|
| 28. | Thermosets cannot be melted, therefore, once a thermoset has set it is impossible to weld it.
|
| 29. | Many advanced thermoset polymer matrix systems usually incorporate aramid fibre and carbon fibre in an epoxy resin matrix.
|
| 30. | There are also thermoset polyurethanes shown to have transient properties and which can thus be reprocessed or recycled.
