Raw material processing and conditioning

Peripheral equipment for adding gas and blowing agents, plus raw material conditioning & manipulating systems

For the end product to achieve the desired properties, it will be necessary in some applications to condition the raw material systems used by a metered additon of technical gases, blowing agents or solids such as nitrogen, natural carbon dioxide, PENTANE or calcium carbonate. To this end, Hennecke offers proven peripheral equipment ensuring the desired production results from both an economic and ecological perspective. At the user's request, our machinery and equipment can also be supplied with conditioning and manipulating systems for the raw materials used, e.g., to control product properties by a metered addition of fluids and solids.

PENTAMAT

Premixing station for the reliable metered addition of blowing agents such as PENTANE

PENTANE (hydrocarbon) is an environmentally compatible blowing agent that eliminates the need for using CFCs in the production of rigid and integral skin foams. Instead of metering blowing agent directly in the mixing chamber, the processing of PENTANE takes place batch-wise within a carrier...

CARBOMAT

Metering unit for CO2 loading in a batch process

The effective pre-expansion of the reactive mix (froth effect) is of special advantage to flexible polyurethane foam applications. Very small amounts of CO2 are particularly appropriate for this. Hennecke's CARBOMAT is a blowing agent metering unit for charging polyurethane...

AEROMAT

Metering unit for charging the polyol component with gas

The release of very fine gas bubbles into the reactive mix – known as nucleation – is responsible for cell formation and for the later cell structure of foamed polyurethane products. The gas charge on the polyol side is thus indispensable for certain PU applications. When producing...

Additive processing

Metered addition of liquids and processing of solids

The properties of polyurethane systems can be significantly improved by a wide variety of additives, both liquid and solid. Apart from the fact that raw materials are prepared in a batch process, sometimes liquid additives such as flame retardants have to be metered into the mixhead directly...

Melters

Equipment for liquefying highly viscous raw materials and granulates

Raw materials are often in solid form when elastomer systems are processed. This means that they have to be liquefied in the metering machine before they are processed further. For materials stored in drums, Hennecke customers make use of melting chambers. Different types of granulates are...
