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.
