Fenofoam integral and semi-rigid foam systems

Moulded parts based on Fenofoam integral foam systems are characterized by a compacted, compact outer skin. This so-called integral skin protects the softer foam core from external influences and thus significantly expands the range of applications. The integral skin is generated by a physical blowing agent during the exothermic reaction of polyol and isocyanate. The densified edge zone guarantees high abrasion resistance and gives the molded part optimum resistance to moisture and many chemicals. The surface hardness of the molded parts can also be varied across the entire Shore A range, so that the final mechanical properties can be directly adapted to the respective application. In addition, an optional flame retardant finish means that molded parts based on Fenofoam integral foam systems also comply with current fire protection standards.

Fenofoam semi-rigid foam systems are purely water-driven PUR formulations. Foam parts produced in this way do not have a compacted and clearly defined edge zone. However, the major advantage of Fenofoam semi-rigid foam systems is the more favorable environmental profile (no physical blowing agents), and the final properties of the molded parts can be adjusted extremely precisely and uniformly over the entire cross-section. This results in sustainable semi-rigid foams that are characterized by very high abrasion resistance and resistance to many external influences.
