Dow announced at the 2nd Automotive Pipeline System Innovation Technology Summit in 2018 that it will introduce a new SILASTICTM fluorosilicone rubber for automotive turbocharger tubes in China.
The company will show the test results of this product: The material has excellent heat resistance, tear strength, pressure change performance, and good adhesion to the outer layer of the pressurized tube.
Shanghai, July 12, 2018 — Silicon, a global leader in silicon-based technology and innovation Dow's Performance Silicone Division announced today at the 2018 Second Automotive Pipeline Systems Innovation Technology Summit hosted by ATC Introduced the new SILASTICTM fluorosilicone rubber (FSR) for automotive turbochargers in China and demonstrated the results of laboratory tests of this high performance material over conventional fluorocarbon rubber 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 and booster tube pressure requirements. Dow Performance Silicone will also showcase A new product in the turbocharger coextrusion process that improves processability.
Zhejiang Junhe Rubber Technology Co., Ltd., located in Yuyao City, Zhejiang Province, is one of the first Chinese customers to use the new SILASTICTM fluorosilicone rubber (FSR), which produces the turbocharger for gasoline vehicles for Peugeot Citroen (China).
Yang Xinjie, Regional Marketing Manager for Silicone Elastomers in Greater China, Dow High Performance Silicones Division, said, 'As fuel economy and emissions control requirements become more stringent, the temperature of the customer's turbocharged engine intake system rises sharply. High, this requires high performance turbocharger material that withstands extreme temperatures and corrosive chemical environments. The Dow High Performance Silicones Division has greatly improved our fluorosilicone technology, the new SILASTICTM material for pressurized tube linings. , 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 and urea resistance and adhesion to solid rubber (HCR) compared with fluorocarbon rubber.
Turbotubes are more demanding
Compared to conventional engines, turbocharged diesel and petrol engines convert more fuel energy into power, helping to improve fuel efficiency and control emissions. However, the hot-end turbotubes of such engines are at up to 220 °C. In addition to the high temperature and higher compressed air pressure. In addition, the turbocharger must meet another requirement: oil resistance to the engine oil contained in the airflow. Fluorine lining as a barrier to avoid the booster tube Contact with engine oil causes 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, at high temperature (225 ° C) and low temperature (-20 ° C The lower elongation at break is higher, and the compression set at high temperature is stronger, and it has good resistance to acetic acid and urea. The material is suitable for coextrusion process and hand bag process, and has high density rubber (HCR). Excellent initial and continuous adhesion. 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's High Performance Silicones Division has developed an optimized multi-layer coextrusion process for turbocharged tubes that increases throughput.
