Altropol Kunststoff GmbH
Stockelsdorf · HeiligenhausNew on Amplifa
Specialist for duromer plastic resin systems since 1994
Since 1994, Altropol Kunststoff GmbH has developed and produced duromer plastic resin systems at its headquarters in Stockelsdorf near Lübeck as well as at its training and development center in Heiligenhaus. On more than 12,000 m² of production space, ready-to-process epoxy resin systems, polyurethanes, RTV silicones, epoxy and polyurethane foam systems, color pastes and polyols based on renewable raw materials (rapeseed, sunflower, soybean and castor oil) are produced, sold under the brands NEUKADUR, NEUKASIL, AltroColor, AltroFoam, AltroGreen and NEUKAPOL. The range comprises more than 2,000 products, including casting resins, encapsulation compounds, laminating and vacuum infusion resins, structural adhesives and hybrid impregnations. In addition to standard products, the family-owned company offers individual product development, application technology consulting and a training center for polyurethanes. The systems are used, among other things, in model, mold and tool making, in prototyping, in foundries, in the automotive and aerospace industries, in construction chemistry, medical technology, orthopedics as well as in the sports and leisure sector, and are delivered worldwide.

Materials and processes
Epoxy resin systems (NEUKADUR)
Ready-to-process systems with high mechanical strength and good media resistance, used among other things as casting, encapsulation, laminating and infusion resins.
Polyurethane systems (NEUKADUR)
Castable, pasty or sprayable 2-component systems, including PU-RIM resin processing (ProtoRIM) for prototypes through series parts.
RTV silicones (NEUKASIL)
Condensation and addition crosslinking silicones as a mold-making material and for elastic finished parts, e.g. in orthopedics and medical technology.
Polyols based on renewable raw materials (NEUKAPOL)
“Green” polyols from rapeseed, sunflower, soybean and castor oil as raw materials for polyurethane chemistry.
Color pastes (AltroColor)
Pigment preparations with software-controlled color formulation for coloring polyurethanes, epoxy resins, polyurea and polyaspartic systems.
Epoxy and polyurethane foam systems (AltroFoam)
CFC-free flexible and rigid foams, processable by hand and machine, among other things for lightweight construction.
Sustainable EP and PUR systems (AltroGreen)
Adhesives, vacuum infusion and casting resins based on sustainable raw materials.
Structural adhesives (AltroBond)
Epoxy and PU-based adhesives for steel, aluminum, rubber, ceramics, wood, acrylic and composite materials.
Hybrid impregnation (Altrosil)
Pollutant-free impregnation for concrete, stone and wood in sustainable construction and renovation.
Laminating and multipurpose resins
For the production of composite materials with glass, carbon and aramid fabrics as well as flow models.
