Fiber-reinforced and low-volatility LSRs are being launched at NPE2015 by Momentive Performance Materials, Waterford, N.Y.
• Applications requiring the features of silicone rubber and the strength of fiber reinforcement—such as wrist bands for wearable electronic devices, can obtain the combination of mechanical properties by using MPM’s new Silopren Matrix 70 fiber-reinforced LSR. Compared to standard LSR of the same hardness, this material has demonstrated 30% higher torsion resistance and 100% higher modulus—properties that may save manufacturers the cost of incorporating a fabric layer into their products. Silopren Matrix 70 also boasts excellent UV resistance and can be easily colored. The product may also be considered for use in some healthcare applications such as wearable electronics or diaphragms pursuant to FDA regulations and ISO 10993.
• The company’s new non-post-cure, low-volatility self-lubricating LSR Silopren LSR 3376/50 boasts very low volatile levels without post-curing. It is engineered to help automotive manufacturers produce electrical connector seals that meet increasingly stringent safety specifications, This is the first product in MPM’s new low-volatility, self-lubricating LSR family. It has a 3% oil content and contains less than 350 ppm of total volatiles. The material typically has a nominal hardness of 50 Shore A, a low compression set of 16% and its can be easily colored. The material was developed to meet new stringent global automotive specifications.
