It sounds as if they are tiny flakes of rubber-like material.

Elastic response of rubber-like materials are often modeled based on the Mooney-Rivlin model.

The floor was of a white rubber-like material that yielded under their bare feet.

The tubes are made of Silastic, a rubber-like material that has long been in use in surgical implants.

Equivalently, relatively small triaxial stretch states can cause very high stresses to develop in a rubber-like material.

This phenomenon was recently also verified by experiment of fracture in rubber-like materials.

It is then dried to form an inelastic rubber-like material.

Before the year 2000 lasers only produced lower quality in rubber-like materials.

In these rubber-like materials, which had a rough structure, higher quality was impossible.

This had also an effect on the rubber-developers who, in order to stay competitive, developed new high quality rubber-like materials.
