Silopren LSR 2641 TP 3730 is a two-component liquid silicone rubber for injection moulding processes.Silopren LSR 2641 TP 3730 shows in comparison to Silopren LSR 2640 as non post-cure grade (NPC grade)a lower compression set after vulcanisation.

Key Features and Benefits

Vulcanisates consisting of Silopren LSR 2641 TP 3730 are distinguished by the following properties:

non post-cure

high reactivity

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

Potential Applications
Because of the outstanding properties Silopren LSR 2641 TP 3730 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.
