Silopren™ LSR 2003 liquid silicone rubber is a two-component product formulated for use in liquid injection molding to produce elastomeric parts where low-durometer is a key requirement. LSR2003 elastomer is clear, but easily pigmentable with Momentive Performance Materials masterbatch colors.LSR2003 elastomer offers a convenient 1:1 mix ratio and releases easily from molds. Cure time is rapid, generally 10 to 40 seconds at 150°C (302°F) - 204°C (400°F), depending on part size, configuration, and molding temperature.Key Features and BenefitsLSR2003 liquid silicone rubber is distinguished by the following properties: Low-Durometer Non-Tackiness Sensory Characteristics (Added Cushioning) Rapid molding cycle times - > 20-60 seconds Convenient 1:1 Mix Ratio Potential ApplicationsThe combination of low-durometer and non-tackiness allows the product to be used in consumer goods applications such as: Corn Pads Heel Inserts Shoe Insole Vibration dampers.
