Fiber-reinforced & low-volatility LSRs.

Fiber-reinforced and low-volatility LSRs were 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 this combination of properties with new Silopren Matrix 70 fiber-reinforced LSR. Compared with standard LSR of the same Shore 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 be considered for use in some healthcare applications, such as wearable electronics or diaphragms.

Momentive's new self-lubricating Silopren LSR 3376/50 boasts very low volatile levels without post-curing. It is engineered for automotive electrical connector seals that must meet increasingly stringent safety specifications. This is the first product in a 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, low compression set of 16%, and easy colorability.
