As against the conventional DUNLOP process, the method I invented is working on the basis of high
frequency heating technology, by which the water molecules inside the latex foam are heated by high
movement caused by their dipole character. Without the diversion through metal, the latex foam is reaching
vulcanization temperature within minutes! This means substantial energy and time saving.
The advantages of this new production process can be summarized as follows:
•
High Energy Saving
•
Export Product Quality
•
Reduced Space Requirements
•
High Flexibility in Shapes and Sizes
•
New Designs and Product Features
•
Faster Reaction to Market Response
•
Faster ROI
•
Higher Profit
•
In-house Manufacturing of Moulds
This is not the place to enumerate all possibilities - of which up to now not all have been
realized - but in a personal meeting I would be glad to discuss further details with you.
The HF heating is also used for the drying of latex foam: Similar to the textile
industry where fibre and yarns have to be dried after dyeing or washing the HF
heating is also the first choice to dry latex foam. The density of latex foam ranges
from 40 g/l for pillows only to 90 g/l for mattress cores. The rest of the volume is air
and this air - it is self-explanatory - works as an insulator. Drying of mattress cores
and pillows with hot air requires very long tunnels with corresponding high energy
consumption, the more so if the residual moisture becomes virtually zero. The HF
technology of heating water direct without any detours shortened the drying time and
efficiency dramatically.
