Raw material, durability and safety

Raw material, durability and comfort guaranteed

The Amorim Sports' developed cork infills combine a certified origin with the materials’ durability and comfort for users.

Natural raw materials

What is the source of the chemical materials and elements used in plastic- and rubber-based infills? Despite the strict rules on raw materials that can be used to produce synthetic infills, concerns remain regarding the potential use of poorer-quality materials or materials from an unknown source.

This is not the case for cork infills, as this type of filling is made up of 100%-natural materials obtained from cork bark and, for Amorim Sports, completely free from chemical contamination pursuant to REACH, an EU regulation on the registration, evaluation, authorisation and restriction of chemical products.

A quality profile enhanced through the use of cork mainly from forests certified by the Forest Stewardship Council (FSC) and/or by the Programme for the Endorsement of Forest Certification Schemes (PEFC).

The durability of cork and its properties are easily understood by considering the material’s best-known use: stoppers.

In 2010, 30 bottles of champagne were found in the Baltic Sea, estimated to have been under water for over 200 years. According to specialists, the shipwrecked champagne was in “excellent condition”, testimony to the unique ability of cork stoppers to preserve wine and champagne for an indefinite period of time.

  • Durability guaranteed


    This endurance capacity extends to cork infills, which when exposed to aggressive agents such as sunlight, record level 2-resistance in accordance with EN 20105-A02 (change in colour after simulating exposure to sunlight).

  • Does cork infill limit granulate agglomeration?

    When subject to higher temperatures or increased pressure, non-organic infills, particularly EPDM, tend to soften or agglomerate, creating granules. These agglomerates are hazardous for players and increase the likelihood of injuries. Furthermore, if the performance infill is agglomerated, it loses optimal performance capacity in terms of shock absorption. Amorim Sports cork infills do not agglomerate and meet all player safety requirements.


Given its unique cellular structure, cork has a high shock-absorption capacity and thermal conductivity. These characteristics, together with a natural texture and appearance, make cork infills a non-aggressive solution for players, guaranteeing system performance and reducing wear and tear.
