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

The actual costs will vary with polymer grade, filler level, and specialty ingredients. This is meant only to be a guide for assistance. If you have specific questions, please contact us. We will be glad to help you further.
