Momentive Develops Self-Bonding Liquid Silicone Elastomers

September 30,2016

New self-bonding family of Silopren liquid silicone rubber improves adhesion performance between silicone elastomers and selected thermoplastics


WATERFORD, N.Y. (September 30, 2016) – Momentive Performance Materials Inc. (Momentive) will globally launch the Silopren* LSR 27x9 liquid silicone rubber family at K 2016, the 20th International Trade Fair for Rubber and Plastics. This new self-bonding material addresses the rising demands for hard-soft designs, helps to achieve the bonding between silicone and thermoplastics, reduces assembly steps and meets various complex design requirements.


Consumer electronics, medical device, automotive and industrial manufacturers seek advanced adhesion technology between silicone elastomers and certain engineering plastics including PC (polycarbonate), PBT (polybutylene terephthalate) and co-polyesters in order to improve performance characteristics such as waterproofing, protection, durability and functionality. Momentive’s new self-bonding LSR technology offers a primerless solution that enables the combination of two materials via a two-shot over-molding process for a hard-soft design as well as cost-efficient manufacturing of high part-quantities in one integrated molding process.  Silopren LSR 27x9 liquid silicone rubber does not require surface treatment on the substrates, and offers short cycle times and one step curing in order to help improve productivity and enhance design freedom.


"Momentive continues to lead the market in developing silicone elastomer solutions that enable design complexity and manufacturing efficiency,” said Holger Albrecht, Vice President, Elastomers. “Our newest offering advances adhesion technology for molded parts that have been previously unavailable in the market.”


Representatives from Momentive will be available in Stand B15 in Hall 6 to discuss Silopren LSR liquid silicone rubber well as a full line of their silicone elastomers and customized solutions. For more information, visit
