40 SHORE A POLYURETHANE ELASTOMER
RoHS
BJB s F-1 Series , with its 3 to 10 minutes of work time, addresses the need for shorter processing times and higher part
production. These 5 to 95 Shore A products exhibit excellent physical properties and easily process at room temperature. You ll
also find the easy mix ratio to be extremely convenient and cartridge dispense friendly. For longer work times consider our M
Series or L Series of elastomers.
RoHS/REACH Compliant Roto-Cast Parts * High Tensile & Tear Strength
