The following cost comparison shows the ratio of prices for selected materials to the lowest cost elastomers: EPDM, SBR, and natural rubber.
|EPDM, SBR, Natural Rubber||1:1|
|Nitrile (NBR), Polybutadiene, Chloroprene, Carboxylated NBR||1:1-2|
|Butyl, Epicholorhydrin, VAMAC||1:2-4|
|Polyurethane (ester, ether)||1:2-6|
Actual costs will vary with polymer grade, filler level, and specialty ingredients; this chart 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.
