MultiFlex - efficient production systems for making slabstock on polyether basis
MultiFlex systems meet complex requirements in terms of economic efficiency, quality, flexibility, environmental compatibility as well as health and safety at work. MultiFlex systems are based on field-proven plant technology, yet available at a very attractive price.

Many different polyether-based foam types can be produced depending on the individual system version:
Standard foams
Extra light-weight foams
High-resilience foams
Viscoelastic foams
HR foams

NovaFlex® - environmental protection to the point of perfection
MultiFlex systems come as an option with Hennecke's patented NovaFlex® system. This is a technology that allows manufacturers to make low-density slabstock (< 20 kg/m³) without using typical blowing agents, such as CFCs or methylene chloride because NovaFlex® production is based on naturally-occurring CO2 as a physical blowing agent instead.

Excellent raw-material yield
Ether-based flexible slabstock manufactured on Hennecke machines with integrated flat-topper have the following key features:

Better material yield than conventional domed-block processes
Blocks with optimised rectangular cross-sections
Higher material yield because hard and thick outer crust is made into useable foam
Improved density and hardness distribution
Thin and smooth surfaces on all block sides
   
Great production reliability
Individually dimensionable metering units ensure precision metering of all components across all viscosity ranges and provide accurately reproducible quantity settings.

Customised automation
MultiFlex systems have a network by which all data processing and control levels are interlinked. Tangible advantages are:

Process-integrated control, monitoring and data management
Fast on-the-fly formulation and machine parameter changes
Short transitional foam pieces when colours and formulations are changed
Accurately reproducible product­ion parameters
Great process reliability
Elimination of production line adjustment errors caused by operators
Fewer human resources needed


Adjustable and reproducible quality
MultiFlex systems have stationary mixer units with effective high-pressure injection of isocyanate and additional components as well as an extra stirring stage, which together with the liquid laydown device ensure that foam blocks have next to no void and an excellent, uniform cell structure.



High-quality film and sheeting material
Hennecke's equipment ensures that slabstock can easily be further processed into high-grade sheeting of any thickness.


Uniform reaction status, laminar liquid laydown
The MultiFlex conveying system is based on the fall-plate principle. Laminar mixture discharge plus thin layer distribution ensure a uniform reaction status of the raw material mix across the entire conveyor width.
