ELASTOSIL® LR 3852/50 A/B

Chemical Family
Silicones

ELASTOSIL® LR 3852/50 A/B is a low-oil-bleeding liquid silicone rubber of the ELASTOSIL® LR 3852 series. It is a paste-like, easily pigmentable, two-component product with short curing times and very good demoldability (high hot tear resistance). Shortly after curing, a thin oil film with lubricating properties forms on the surface. The vulcanizates are opaque, have very good mechanical and electrical properties, excellent cut resistance, and a low compression set without post-cure.
