Principle
The reaction of sebacoyl chloride with hexamethylenediamine forms Nylon 610®. The two components are dissolved in two solvents of different density which do not mix with one another. For this reason, a reaction can take place only at the contact su ...
The reaction of dialcohols with diisocyanates forms polyurethane. This is an example of a polyaddition reaction. The reaction releases heat which causes a foaming agent (water) to foam up the plastic that is formed.
Polystyrene containing n-pentane as a foaming agent can easily increase its original volume by 20 to 50 times when heated with steam. If pre-foamed polystyrene of this type is sintered together in a closed mould to make a section with a closed cell structure, th ...
