Silicone Charge Air Cooler Hoses with Inner Layer of Fluorosilicone

Silicone Charge-Air-Cooler Hoses (which are exposed to heave pressure, heat and oil mist) are sometimes lined on the inside with a inner layer of Fluorosilicone. This is because Silicone by itself is not oil-resistant. The Fluorosilicone liner gives very good resistance to Oil and most types of Fuels, and their mists.

Fluorosilicone have similar “cold-resistance” as Silicone, and the heat-resistance for the normal grades is 220 deg C / 428 F.

The advantage of Fluorosilicone is also that is can be compounded in low hardness, for e.g. 50 Shore A.

However, bonding Fluorosilicone (FVMQ) to Silicone (VMQ) is not easy.

At Shore Auto Rubber Exports Pvt. Ltd., we now use a very advanced grade, which has been developed by a global leader, especially for Turbocharger Hoses.

The Advantages are:

• 30% better bonding between the Silicone and Fluorosilicone
• Better heat-resistance for long-term. It has been tested to perform at above 225 deg C / 437 F for long time-periods. The testing carried out at the Laboratory has for the first time been done at 225 deg C / 437 F, for 42 days, and the change in properties are remarkably low.
• Excellent Physical Properties (Tensile Strength, Elongation %, etc.)
