Dow Corning Offers Enhanced Elastomers for Turbocharger-Hose Applications

Silastic brand of silicone and fluorosilicone engineered elastomers is offered by Dow Corning for application in today’s turbocharger hoses, including crossover and intercooler hoses. These elastomers feature improved adhesion properties that helps to decrease processing costs and enhance service reliability for high-strength turbocharger hoses.

Silastic elastomers offer two major benefits in today’s turbocharger hoses: they surpass the performance of several organic elastomers in harsh operating situations and the enhanced inter-layer adhesion enables efficient and cost-effective co-extrusion processing, according to Son.

Silastic engineered elastomers are available as heat-cured standard compounds for direct use. These materials can be custom-made to address special processing requirements. For today’s turbocharger-hose uses, suggested elastomers include fluorosilicone rubber (FSR) compounds for inner layers of hoses and high consistency silicone rubber (HCR) compounds for hard, heat-resistant outer layers.

The enhanced silicone and fluorosilicone engineered elastomers has an ability to resist higher underhood temperatures about and over +200°C. They maintain a high burst strength at extreme pressure and remain flexible in freezing cold with less hardening, brittleness or hardening. Several organic elastomers get deformed and softened at temperatures greater than 100°C and turn fragile at temperatures less than -25°C. Dow Corning’s silicone and fluorosilicone elastomers can be co-extruded in a cost-effective way with the use of the patented technology. In addition, the technology enhances reliability, strength and integrity of hoses.
