Abstract:
1. A biopharmaceutical tube comprising an electron beam radiated crosslinked blend of: a first elastomeric polymer comprising a diene elastomer including a polybutadiene, polyisoprene, or a terpolymer of ethylene, propylene and a diene monomer; and a second elastomeric polymer comprising a polyolefin elastomer including a homopolymer, a copolymer, a terpolymer, an alloy, or a combination thereof formed from at least one monomer selected from the group consisting of ethylene, propylene, butene, pentene, methyl pentene, hexene, octene, or combinations thereof, wherein the first elastomeric polymer comprising a diene elastomer is present in an amount of at least 50% by weight based on the combined weight of the first and second elastomeric polymers, and wherein the tube has an elongation of at least 400%, a shore A durometer of about 50 to about 90, a compression set of less than 50% at a temperature of 121° C., and a 100% Modulus in a range of 1.7 to 3.0 MPa.
