Rubber Material Guide

Many people think of "rubber" as being a single type of material. But in the 20th century, synthetic products were developed as a means to have rubber-like properties while adding improved characteristics that natural rubber lacked. These other rubber-like materials are advantageous to use for certain situations, such as their contact with certain liquids like acids or hydrocarbons, temperature resistance, and exposure to sunlight, weathering or abrasion. 

The chart below is designed to help convey information about the best rubber material to use for a given application as it applies to the finishing / coating industry and masking projects. Check out the typical rubber materials Viadon both stocks and can have made (Silicone / EPDM / Neoprene) and compare how they perform relative to natural rubber.
