 back to PUR at THIEME |
The PUR system used at THIEME is made up of the two components:
|
polyol a mixture of polyols, activators, flame retardants, coloring agents, fillers
|
isocyanate |
|
The liquid starting components are conveyed to a mix head by means of a high-pressure pump metering unit. They are mixed in the correct ratio and metered into a closed, temperature-controlled mold.
|
The chemical reaction that takes place in the mold produces a stress-free structural molding from the raw materials mixture. Since a chemical reaction of the 2 raw componets takes place in the mold, the process is called Reaction Injection Molding.

 |
In industrial production the two components are conveyed by pipeline to the foaming plants. Each foaming plant can be fitted with up to 20 mold carriers.
