Silopren™ LSR 2640
- Chemical Family
- Silicones
Silopren™ LSR 2640 is a two-component liquid silicone rubber for injection molding processes. In comparison to Silopren™ LSR 2040, Silopren™ LSR 2640 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 BenefitsVulcanizates of Silopren™ LSR 2640 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 ApplicationsBecause of its outstanding properties, Silopren™ LSR 2640 is an excellent candidate to consider for the following elastomeric articles: Sealing elements O-rings Stoppers Diaphragms Keypads Bellows Catheters Pacifiers Baby teats Respiratory devices Vibration dampers Air vent flaps Switch cover Breast shields Nose pads Cable connectors Parts of medical technical equipment.
