Silopren™ LSR 2651

Chemical Family
Silicones

Silopren™ LSR 2651 TP 3731 is a two-component liquid silicone rubber for injection molding processes.Silopren™ LSR 2651 TP 3731 shows in comparison to Silopren™ LSR 2650 as non post-cure grade (NPC grade)a lower compression set after vulcanisation.Key Features and BenefitsVulcanisates consisting of Silopren™ LSR 2651 TP 3731 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 aging, excellent dielectric behavior over a wide range of temperatures, not readily combustible, does not melt or drip easy pigmentable with the LSR Color Pastes Potential ApplicationsBecause of the outstanding properties Silopren™ LSR 2651 TP 3731 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.
