HC Plastics News: Dow announced at the 2nd Automotive Pipeline System Innovation Technology Summit in 2018 that it will introduce a new SILASTICTM fluorosilicone rubber for automotive turbo tubes.
The company will demonstrate the test results of this product: the material has excellent heat resistance, tear strength, pressure change properties, and good adhesion to the outer layer of the pressurized tube.
Shanghai, July 12, 2018 - Dow's High Performance Silicones Division, a global leader in silicones, silicon-based technology and innovation, announced today at the 2018 Second Automotive Pipeline System Innovation Technology Summit hosted by ATC The new SILASTICTM fluorosilicone rubber (FSR) for automotive turbotubes was introduced in China and the results of laboratory tests of this high performance material compared to conventional fluorocarbon rubber were demonstrated at the summit. The new SILASTICTM fluorosilicone rubber (FSR) offers the following key performance enhancements: greater heat resistance and higher tensile strength to meet automotive engine temperature rise and booster tube pressure requirements. The Dow High Performance Silicones Division will also showcase new products for the turbocharger coextrusion process to improve processability.

Yang Xinjie, Regional Marketing Manager for Silicone Elastomers in Greater China, Dow High Performance Silicones Division, “As the requirements for fuel economy and emission control are becoming more stringent, the temperature of the customer's turbocharged engine intake system rises sharply. High, this requires high-performance turbotube material that withstands extreme temperatures and corrosive chemical environments. The Dow High Performance Silicones Division has greatly improved our fluorosilicone technology for the booster tube lining , now available in China, helps the automotive industry use turbocharging technology to improve vehicle sustainability and performance."

Report on new fluorosilicone rubber
Dr. Shi Qing, Senior Technical Service Manager of Silicone Elastomers Greater China in Dow High Performance Silicones Division will hold the 2018 2nd Automotive Pipeline System Innovation Technology Summit held at ATC from 17:00 to 17:30 on July 12th. The keynote report entitled "The Solution for Dow Fluorosilicone for Turbo Boosters" was published. The main content of the report is the test results of SILASTICTM fluorosilicone rubber (FSR), and the heat aging of the material, High temperature and low temperature resistance, oil resistance, acid resistance and urea resistance, and adhesion to solid rubber (HCR) are compared with fluorocarbon rubber.
Turbotubes are more demanding
Compared to conventional engines, turbocharged diesel and gasoline engines convert more fuel energy into power, helping to improve fuel efficiency and control emissions. However, the hot end turbotubes of such engines are subjected to high temperatures of up to 220 ° C and higher compressed air pressures. In addition, the turbocharger must meet another requirement: oil resistance to engine oil contained in the air stream. The use of a fluorinated liner as a barrier prevents the tube from being in contact with the engine oil causing tube wall expansion and possible cracking.

SILASTICTM fluorosilicone rubber (FSR) has a high temperature resistance of up to 210 ° C, a peak temperature of up to 250 ° C and excellent oil resistance. Compared with fluorocarbon rubber, the tensile elongation at higher temperature (225 ° C) and low temperature (-20 ° C) is higher, and the compression deformation performance at high temperature is stronger, and also has good resistance to acetic acid and urea. This material is suitable for coextrusion and hand-wrapped processes with excellent initial and continuous adhesion to high density rubber (HCR). In contrast, fluorocarbon rubber has a strong initial adhesion to high-density rubber (HCR), but it only drops rapidly after one day of heat aging.
Other potential automotive applications for SILASTICTM fluorosilicone rubber include: fuel line safety seals, fuel system seals, valve plates, membranes, O-rings and gaskets.
To support this innovative technology, Dow High Performance Silicones has developed an optimized multi-layer coextrusion process for turbocharged tubes to increase throughput.
