What is the role of silicone sheets in automotive turbochargers?

In automotive turbochargers, high-temperature resistant silicone sheets are not directly applied as a single piece. Instead, they are punched or laser-cut into specific shapes, such as gaskets, seals, heat shields, and bushings. These are then installed in three key locations to seal high-temperature gases/oil, compensate for thermal expansion, and reduce vibration and noise.

What is high-temperature resistant silicone rubber sheet?

Firstly, high-temperature resistant silicone rubber sheet is used in the production of various high-temperature resistant seals, rubber rollers, sealing strips, and other hardware and electrical equipment. High-temperature resistant silicone rubber sheet is a material suitable for the production of various high-temperature resistant seals, rubber rollers, sealing strips, and other hardware and electrical equipment, as well as applications in the electrical, electronic, aerospace, medical, printing, and high-voltage insulation industries.

What will happen to the silicone sheet under low temperature environment?
At low temperatures, silicone sheet will become hard and brittle, decreased flexibility, easy to rupture when subjected to external forces, in the cold areas of outdoor equipment sealing, which may lead to not be able to effectively play the role of sealing buffer.

Silicone Foam Sheets
Softer than sponge sheets, with more pores, great for shock absorption and insulation but less tough. Perfect for padding in electronics, battery cushions, or packaging.

Silicone Sponge Sheets

Light, soft, and compressible with a fabric-like feel. Great for insulation and sealing uneven surfaces, good for -50°C to 200°C. Used in HVAC, electronics, or medical gear for seals and cushioning.
