Called the Zero Age Applicator, firm says it is a new way of dispensing polyurethane foam "which offers a convincing alternative to the discharge systems previously available."
The new development is designed to give uniform distribution over the foaming width combined with a foaming reaction that starts precisely at the same time, Hennecke said.
"With this system, several injectors are arranged in a semi-circle in the discharge unit and so homogeneously mixed material is dispensed onto the bottom sheet in several streams across the entire foaming width. The reaction starts at the same time across the entire foam width: the foam cells form in one virtual line without any time delay, or indeed with a zero age difference," the company explained.
The Zero Age Applicator, is offered in two variants. The continuously manufactured sandwich panel version allows insulation elements with an extremely homogeneous foam structure to be produced.This leads to an improvement in insulating properties, Hennecke added.
The flexible slabstock foam version "ensures improved efficiency of raw materials as well as a significant shortening of transition pieces when changing formulation or colour, ultimately resulting in less waste" Hennecke said.
Hennecke said that the new development has been extensively tested in simulations and under real production conditions and is designed to be easy to handle and easily clean for a wide range of applications.
