Material Notes:

PELLETHANE® 2102-90AR elastomer is a polyester polycaprolactone based polyurethane elastomer which combines excellent resistance to fuels and oils with enhanced mold release, low compression set, and good hydrolytic stability compared to other polyester based TPUs. Its typical applications include seals, gaskets, belting, animal ID tags, and other fabricated products.Data provided by Dow Chemical.Lubrizol acquired the Pellethane product line from Dow in 2009.
