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 materials through a metered addition of specific gases, blowing agents or solids such as nitrogen, natural carbon dioxide, pentane or calcium carbonate. For this, Hennecke offers proven peripheral equipment designed to deliver desired production results with both economic and ecological benefits. At your request, our machinery and equipment can also be supplied with conditioning and manipulating systems for the raw materials used to control performance properties through the metered addition of fluids and/or 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 rigid and integral skin foams production. Instead of metering the blowing agent directly into the mixing chamber, the addition 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. Additions of very small amounts of CO2 are particularly appropriate. Hennecke's CARBOMAT unit is a blowing agent metering unit for charging...

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 final 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 liquid and solid additives. While raw materials are prepared in a batch process, sometimes liquid additives such as flame retardants have to be metered into the mixhead directly online, or into the flow...

Melters

Equipment for liquefying highly viscous raw materials and granulates

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