From open to closed pore, fine and coarse pore, in variations from flexible to rigid, at Bachmann Kunststoff Technologien GmbH you will find a multitude of foam systems.
Foam systems are available in a hardness range from approx. Shore A 10 to approx. Shore D 50, also formulated to be flame protected, visco-elastic or halogen-free. Without CFCs, instead HFCs, pentane and water used as foaming agent giving this group of foams its characteristic, compact outer skin.
Whether directly cast seals, upholstered furniture, car seats or mattresses, the flexible elastic foam systems are used for many applications even for toys and sports goods. It is primarily the carbon dioxide released in the chemical reaction between isocyanate and water that serves as foaming agent for these systems.
This group of systems is predominantly used according to the foam injection method for instrument panels and interior trim for motor vehicles for example. The main difference compared to the semi-rigid – integral foam group is the absence of a pronounced outer skin, whereas the transition to rigid foams on the one hand and to flexible foams on the other is indistinct.
Its excellent insulation properties and halogen-free fire-protection properties open up a large number of applications. This application range is extended by extremely light packaging foams as well as by the manufacture of glass fibre reinforced components with rigid foam systems.
Self-releasing systems with a good surface for painting as well as equipped with flame retardant agents in a hardness range from approximately 60 to 80 Shore D.
