Silopren® LSR 2620

Silopren LSR 2620 is a two-component liquid silicone rubber for injection moulding processes.Silopren LSR 2620 shows in comparison to Silopren LSR 2020 a lower viscosity, improved tear resistance and a higher reactivity. Therefore, it is also possible to reduce the vulcanisation temperature while maintaining a standard crosslinking rate. The increased reactivity does not affect the properties of the vulcanisate.

Key Features and Benefits
Vulcanisates consisting of Silopren LSR 2620 are distinguished by the following properties:

• high reactivity, lower viscosity, shorter cycle time

• excellent thermal stability

• high stability and flexibility at low temperatures

• good rubber-like properties, high tear resistance

• high stability to ozone and ultraviolet light

• outstanding resistance to ageing,

• excellent dielectric behaviour over a wide range of temperatures,

• not readily combustible, does not melt or drip

• easy pigmentable with the LSR Colour Pastes

Potential Applications
Because of the outstanding properties Silopren LSR 2620 is particularly suitable for the following elastomeric articles: stoppers, vibration dampers, shoe inserts s.o.
