Glossary

C

Cool Plus

Performance infill for artificial turf systems with a special formulation that can contribute to a considerably lower surface temperature (up to 25%).

D

Density

The density of an object is defined as its mass per unit volume. The specific density represents the density of a material in relation to the density of water. In the case of filled materials, such as EPDM granules, the density can be calculated by determining the mass and its displacement of water, for example.

E

ECO

Performance infill for artificial turf systems with even more stringent environmental compatibility requirements than those customary in Germany (e.g. Austria and Switzerland "inhibition of nitrification" or "luminous bacteria tests").

EPDM

Ethylene propylene diene monomer rubber is a terpolymer elastomer. Due to its saturated supporting structure, EPDM is highly resistant to ageing, weathering, UV and ozone.The material is resistant to many acids and alkalis but not to mineral oils. Depending on the composition of the compound, application temperature from -40 °C to +120 °C.

Advantages:

  •  excellent resistance to weathering, ageing, ozone, chemicals, hot water, steam and polar solvents such as acetone, methanol and esters
  • outstanding electrical insulation properties
  • very good heat resistance
  • good behaviour at low temperatures

Disadvantages:

  • ow resistance to aliphatic and aromatic hydrocarbons (mineral oils, petrol and fuels)

Trade names: NORDEL®, KELTAN®, VISTALON®, DUTRAL®, BUNA EP®

F

Flame-retardant

By using mineral flame retardants, EPDM granules can be made flame-resistant (formerly "B1" in accordance with DIN 4102-1, now Cfl-S1 according to DIN EN ISO 13501-1).
