Polysulfide Oligomers |
Rimpex Rubber introduces Polysulfide Oligomers, Thiokols.
Liquid polysulfide oligomers are sulfer-containing reactionable oligomers with active terminal groups, cured into compositions with different fillers. Polysulfide oligomers are viscous homogeneous dark liquid with greenish and brown hue without foreign inclusions. Designed for sealing pastes production, cured at moderate temperatures, using in aviation, shipbuilding, engineering, electronics and civil engineering. Specifications |
