Silopren™ LSR 2650
Silopren™ LSR 2650 is a two-component 50A liquid silicone rubber with low viscosity, fast cure, and high tear resistance for injection molding processes. This silicone elastomer has outstanding thermal stability, allowing it to be used in various processes with temperatures. This LSR has excellent resistance to aging, and a long service life that makes it the perfect candidate for a wide variety of applications, ranging from medical supplies to automotive parts.
Silopren™ LSR 2650, manufactured by Momentive Performance Materials, is a two-component liquid silicone rubber used to injection mold parts. In addition to other properties of the LSR 2050, it has a lower viscosity, faster reactivity, hence, a shorter cycle time.
Specifications
Density: 1.12 g/cm³ Shore A hardness: 52 Tensile strength, N/mm²: 10.0 Elongation at break, %: 550 Compression set (22 hrs at 175°C), %: 25
Primary Chemistry: Liquid silicone rubber
Features & Benefits
High reactivity Lower viscosity Shorter cycle time High stability and flexibility at lower temperatures Stability to ozone and UV light Easily pigmentable Biocompatible Ready-to-use mixtures Self-lubricating Self-bonding
Problems Solved
High viscosity and low reactivity of liquid silicone rubbers for injection molding with fast product cycles Pigmentation issues and biocompatibility concerns of liquid silicones in consumer and health care applications Improved tear resistance and high reactivity allows for reduced vulcanization temperature without affecting the molding and curing processes.
Applications
Sealing elements O-rings Stoppers Keypads Pacifiers Baby teats Breast shields Nose pads Pressure cooker parts Respiratory devices Switch covers Vibration dampers Cable connectors Catheters Automotive parts Aerospace industry materials
