Silopren® LSR 2670

Silopren LSR 2670 is a two-component liquid silicone rubber for injection molding processes. In comparison to Silopren LSR 2070, Silopren LSR 2670 shows a lower viscosity, improved tear resistance and a higher reactivity. Therefore, it is also possible to reduce the vulcanization temperature while maintaining a standard crosslinking rate. The increased reactivity does not affect the properties of the vulcanizate.

Key Features and Benefits
Vulcanizates of Silopren LSR 2670 are typically distinguished by the following properties:

• High reactivity, lower viscosity, shorter cycle time

• Excellent thermal stability

• Biocompatible

• Sterilizable with ethylene oxide, steam and gamma radiation

• High stability and flexibility at low temperatures

• Good rubber-like properties, high tear resistance

• Long service life at dynamic stress

• High stability to ozone and ultraviolet light

• Outstanding resistance to aging

• Excellent dielectric behavior over a wide range of temperatures

• Not readily combustible, does not melt or drip

• Easily pigmentable with LSR color pastes

• KTW approved

Potential Applications
Because of its outstanding properties, Silopren LSR 2670 is an excellent candidate to consider for the following elastomeric articles:

• Sealing elements

• O-rings

• Stoppers

• Keypads

• Vibration dampers

• Pressure cookers parts

• Spark plug boots, catheters, parts of medical technical equipment s.o.
