Silopren LSR 2660 is two-component liquid silicone rubber for injection moulding processes. Silopren LSR 2660 liquid silicone rubber shows in comparison to Silopren LSR 2060 liquid silicone rubber 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

• high reactivity, lower viscosity, shorter cycle time

• excellent thermal stability

• 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 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

• Fulfill the requirement of KTW

Approval

• meets flame retardant class UL 94 HB

• compliance with FDA and BfR Recommendations

• WRAS approved product

Potential Applications
Because of the outstanding properties Silopren LSR 2661 TP 3732 is particularly suitable for the following elastomeric articles: sealing elements, O-rings, stoppers, diaphragms, keypads, bellows,vibration dampers, switch cover, spark plug boots, cable connectors s.o.
