Ceresit Impactum

High mechanical resistance to over 100 J impacts

The system’s very high impact resistance is expressed in its endurance against impacts. Impressive impact resistance (over 100 J) has been achieved by using the composition of elastomers with the mixture of fibres which form the reinforcement framework in the structure of the system. Elastomers are specific dispersions which ensure a high degree of stress transfer in impacts from solid objects.
The reinforcement is made of specially selected types of fibres:

  • glass (long, flexible),
  • carbon (short, rigid),
  • polyacrylamide (very short and highly flexible).

This combination of elastomers and fibres ensures the easy return of the system to its original form after mechanical deformation from an impact, preventing the system from cracks appearing.

Over 100 J impact resistance

Mechanical resistance of Ceresit Impactum System to over 100 J impacts is as much as ten times higher than the ETAG 004 requirements for the highest category of resistance, with over 100 times excess for the minimal class. Striking the system surface with 100 J kinetic energy may be compared with the energy of a football flying at more than 90 km/h or a tennis ball at more than 250 km/h.
