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.
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...
More InformationThe LAMBDAMAT blowing agent metering device from Hennecke offers customers a precise and reliable premixing station for loading the blowing agents of the polyurethane components in a batch process. Here the LAMBDAMAT is primarily designed for the application of HFOs (hydrofluorolefins) and...
More InformationThe 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...
More InformationThe 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...
More InformationUsers who are looking for a system for processing abrasive pigments, chemically aggressive additives or additional components containing fillers can take advantage of the HT30evo as an efficient metering unit for a wide range of possible applications. Hennecke is offering the extremely compact...
More InformationThe 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...
More InformationRaw 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...
More InformationDepending on the different applications, a polyurethane system often requires extremely exact temperature control methods. Hennecke uses industrial chillers with water circulation whose types and dimensions correspond to the pre-calculated heating requirements of the particular raw materials...
More InformationThe new, modular IBC station from Hennecke greatly simplifies handling of the containers, ensures utmost process reliability and also offers an attractive price-performance ratio due to standardization and series production. In addition to a consistently modular construction, the plant concept...
More InformationIn order to produce polyurethane products with a compact structure, dissolved gas must be removed from the raw material. Hennecke's brand new VACUMAT double degassing system safely removes the residual gas from the raw material. The VACUMUT operates under full vacuum and has two degassing...
