Foam Rubber

Some general information on foam rubber I found when researching mattresses.

Latex: (natural rubber)

Polymer: 
  Plastic: Polystyrene, Polyethelene, PVC
  Rubber: CR (chloroprene rubber, neoprene); SBR (styrene butadiene rubber);
    NBR (acrylonitrile butadiene rubber);
    and EPDM (ethylene propylene diene methylene)

Open-cell sponge rubber - air or gas can pass through them similar to the way water is absorbed by a dish sponge.

Closed Cell sponge (expanded rubber) Floats, Functions well as a shock absorbing material.
