Issue 15/2018 - New rubber offers solutions for turbocharged tubes

New rubber provides solutions
for turbocharged tubes Dow Performance Silicones has introduced a new SILASTICTM fluorosilicone rubber
for automotive turbocharger tubes.

The rubber has high temperature resistance with continuous operating temperatures up to 210°C and peak temperatures up to 250°C and excellent oil resistance
.
Compared with fluorocarbon rubber, the rubber has higher elongation at break at high temperature (225 °C) and low temperature (-20 °C), stronger compression set at high temperature, good acetic acid and urea resistance, and excellent initial and continuous adhesion
to high-density rubber.
In addition, the fluorinated lining is used as a barrier to prevent the pressure pipe from coming into contact with the engine oil and causing the pipe wall to expand and rupture
.
Other potential automotive applications for SILASTICTM fluorosilicone rubber include: fuel line safety seals, fuel system seals, valves, membranes, o-rings and gaskets
.

"As environmental requirements become more stringent, the temperature of the intake system of turbocharged engines in customer applications rises dramatically, which requires high-performance turbocharger tube materials
that can withstand extreme temperatures and corrosive chemical environments," said Yang Xinjie, regional marketing manager for silicone elastomers in Greater China, Dow Performance Silicones.
Dow Performance Silicones has significantly improved our fluorosilicone rubber technology, a new SILASTICTM material for pressurized tube linings that helps the automotive industry improve vehicle sustainability and performance
with turbocharging technology.
