Areas of application
Polyurethanes (PUR) belong to the most important polymers.
The technical area of application of PUR goes from "PUR soles" to "PUR foam". The main area of application of polyurethane is the use of foam, e.g., for upholstered furniture, mattresses, sponges, winter clothing, coating for carpets, constructional foam for thermal insulation, packing material, etc.
They are also used as paint and adhesives, as thermoplastic plastics for the production of rollers, rolls, and as elastomers and fibers, e.g. as elastane.
Industries
Chemical Pumps and Metering Packages for the Chemical Industry
When critical, environmentally hazardous, toxic, or flammable fluids and suspensions need to be reliably conveyed or metered in high-pressure processes, there is no alternative to hermetically sealed metering pumps, process diaphragm pumps, and metering systems from LEWA. Hermetically sealed LEWA pumps with pressures up to 1200 bar are the first choice for the production of chemical intermediate and end products. Contact our experts and let us advise you about your individual chemical pump or system solution!
