Cellular rubber mat.
Sheet size 5 x 245 x 495mm
Cellular rubber is basically closed-celled and therefore a water and air impermeable foam made from natural or synthetic caoutchouc (unvalcanized).
This cellular rubber is sulphur-free – which means that it will not discolour silver, copper and many other metals.
In addition it is distinguished by its high tensile strength, elasticity and workability even when cold. EVA (ethylene-vinyl acetate) is a copolymer that is produced with PE as its basis and is distinguished by its softness and flexibility. The synthetic caoutchouc EPDM (ethylene propylene diene monomer rubber) is very resistant to aging, to ozone and to heat as well as insensitive to most chemicals.
The sulphur-free cellular rubber mat is an excellent material for use in jewellery presentation and packaging because it will hinder the tarnishing of, for example, silver. You can also wrap sensitive objects between cellular rubber mats, sleep on the mats (ISO mat), or use them as vibration reducing pads or seals (also against water).
Cellular rubber can be cut with a blade or die-cut or punched using the standard tools. They can be glued using contact cement or cyanoacrylate (e.g. SUPER GLUE).
