The following cost comparison shows the ratio of prices for selected materials to the lowest cost elastomers: EPDM, SBR, and natural rubber.

Material Ratio
EPDM, SBR, Natural Rubber 1:1
Nitrile (NBR), Polybutadiene, Chloroprene, Carboxylated NBR 1:1-2
Butyl, Epicholorhydrin, VAMAC 1:2-4
Silicone 1:2-6
Hydrogenated NBR 1:4-6
Polyurethane (ester, ether) 1:2-6
Fluoroelastomer 1:8-35
Flurorosilicone 1:20-35
