ELASTOSIL® LR 3844/30 A/B
Oil-bleeding liquid silicone rubbers of the ELASTOSIL® LR 3844 series are paste-like, readily pigmentable two-component products with short curing times. Shortly after the curing process, a thin oil film with lubricating properties forms on the surface of the vulcanizates. The vulcanizates are opaque, have good mechanical and electrical properties and very low compression sets.
This product can be used within a temperature range of - 55 °C to + 210 °C. The addition of heat stabilizers at service temperatures of more than 180 °C is recommended. Further information to improve the heat stability by use of specific ELASTOSIL® Color Pastes FL can be obtained from the Technical Information Sheet "ELASTOSIL® Color Pastes FL".
