A turbocharger pipe sees two enemies at once: hot compressed air on the inside, oil mist and fuel condensate soaking through. Standard methyl silicone rubber handles the heat but swells in oil; that is where a fluorosilicone inner layer earns its place.

IOTA F3361 is a fluorosilicone rubber compound developed around the technical demands of automotive turbocharging. Based on fluorosilicone elastomer with a unique formulation process, it meets the strict high-low temperature and fuel resistance requirements of turbocharger pipes. The production advantage is just as important: the compound can be directly calendered and co-vulcanized with methyl silicone rubber without special treatment — peel strength to methyl vinyl silicone rubber reaches 2.2 N/mm — so a composite hose with a fluorosilicone inner layer (calendered at 0.5–1 mm) and a multi-layer woven-fabric-reinforced methyl silicone outer layer can be made by manual or mechanical winding, with a simple process.

Properties (typical values per official product page; not factory standards):

Vulcanization: add 2.0 phr DCBP (bis(2,4-dichlorobenzoyl) peroxide); first stage 180℃×30 min, second stage 200℃×2 h (hot air). Heat-resistant additives must be added to meet heat-resistant requirements.

Applications: automotive turbocharger pipes; oil-resistant pipe fittings for mechanical equipment.
