Momentive Performance Materials Silopren™ LSR 4030 Liquid Silicone Rubber - Healthcare
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	LSR elastomers are a two-component, platinum (addition/heat) curable, and pumpable silicone elastomer that can be molded and cured with very fast cycle times, at elevated temperatures. The molding process allows for complex part geometry and exact dimensions. LSR elastomers are generally suitable for short cycle time injection and full automatic flash-less processing. Color pastes are available to pigmenting addition cure productions of LSR's. All LSR grades are platinum cured materials which are mixed in a 1:1 ratio by weight. The distinctive properties of silicone elastomers - purity, clarity, strength - coupled with ease of processability, have resulted in their use in a broad range of medical device applications. Silicone materials exhibit exceptional stability over a wide range of temperatures, lending themselves to use in applications requiring repeated sterilization performance. Typical applications include, but are not limited to: Dental / surgical devices Diagnostics / imaging Fluid and drug delivery devices Orthopedics / prosthetics Scar management Septa / stoppers / laboratory accessories Medical tubing Wound drains and bulbs Sterilization mats Pharmaceutical closures Instrument grips Dialysis o-rings Positioning devices Catheters Seals / o-rings / valves Respiratory / anesthesia Medical equipment keypads
