Silopren® LSR 3386/40

Silopren LSR 3386/40 is a two-component liquid silicone rubber for injection molding processes. This material is an excellent candidate to consider for the manufacture of elastomeric articles requiring self-lubricating properties. The self-lubricating effect is achieved by a fluid which exudes out of the vulcanizate over an extended period of time. It typically starts between a few hours and one day after vulcanization. Silopren LSR 3386/40 liquid silicone rubber shows a low compression set after vulcanization without post-curing.

Key Features and Benefits
Vulcanizates consisting of Silopren LSR 3386/40 liquid silicone rubber are typically distinguished by the following properties:

• low compression set without post-cure

• self-lubricating properties

• low viscosity

• fast cure

• high thermal stability

• outstanding resistance to aging

• easy to color

Potential Applications
Because of the outstanding properties, Silopren LSR 3386/40 liquid silicone rubber is an excellent candidate to consider for use in wire harness
applications for the following elastomeric articles:

• cable seals

• grommets

• gaskets

• plug seals
