COST COMPARISON
Cost comparison is a ratio to the lowest cost elastomers, EPDM and SBR. For example, NBR will be approximately 1 - 2 times the price of EPDM or SBR based on specific material formulation.Material | Ratio |
EPDM, SBR | 1:1 |
Nitrile (NBR), Polybutadiene, Natural Chloroprene, Carboxylated NBR |
1:1-2 |
Butyl, Epicholorhydrin, VAMAC | 1:2-4 |
Silicones | 1:2-6 |
Hydrogenated NBR | 1:4-6 |
Polyurethane (ester, ether) | 1:4-8 |
Fluoroelastomer | 1:8-35 |
Flurorosilicone | 1:20-35 |
